161-616: The Challenger expedition of 1872–1876 was a scientific programme that made many discoveries to lay the foundation of oceanography . The expedition was named after the naval vessel that undertook the trip, HMS  Challenger . The expedition, initiated by William Benjamin Carpenter , was placed under the scientific supervision of Sir Charles Wyville Thomson —of the University of Edinburgh and Merchiston Castle School —assisted by five other scientists, including Sir John Murray ,

322-548: A 99-year lease of the New Territories in 1898. Hong Kong was occupied by Japan from 1941 to 1945 during World War II . The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems . Originally a sparsely populated area of farming and fishing villages,

483-463: A proposed extradition amendment bill permitting the extradition of fugitives to mainland China. The protests are the largest in Hong Kong's history, with organisers claiming to have attracted more than three million Hong Kong residents. The Hong Kong regional government and Chinese central government responded to the protests with a number of administrative measures to quell dissent. In June 2020,

644-662: A 1,104-square-kilometre (426 sq mi) territory, Hong Kong is the fourth most densely populated region in the world. Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War . The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained

805-427: A acertar: mas partiam os nossos mareantes muy ensinados e prouidos de estromentos e regras de astrologia e geometria que sam as cousas que os cosmographos ham dadar apercebidas (...) e leuaua cartas muy particularmente rumadas e na ja as de que os antigos vsauam" (were not done by chance: but our seafarers departed well taught and provided with instruments and rules of astrology (astronomy) and geometry which were matters

966-845: A four-year term. Twenty are directly elected from geographical constituencies , thirty-five represent functional constituencies (FC), and forty are chosen by an election committee consisting of representatives appointed by the Chinese central government. Thirty FC councillors are selected from limited electorates representing sectors of the economy or special interest groups, and the remaining five members are nominated from sitting district council members and selected in region-wide double direct elections . All popularly elected members are chosen by proportional representation . The 30 limited electorate functional constituencies fill their seats using first-past-the-post or instant-runoff voting. Twenty-two political parties had representatives elected to

1127-441: A line with a weight attached to it until it reached the sea floor. The line was marked in 25-fathom (150 ft; 46 m) intervals with flags denoting depth. Because of this, the depth measurements from Challenger were, at best, accurate to the nearest 25-fathom (150 ft; 46 m) demarcation. The sinker often had a small container attached to it that would allow for the collection of bottom sediment samples. The crew used

1288-491: A neutral zone to safeguard its status as a free port. The colonial government prepared for a possible attack, evacuating all British women and children in 1940. The Imperial Japanese Army attacked Hong Kong on 8 December 1941 , the same morning as its attack on Pearl Harbor . Hong Kong was occupied by Japan for almost four years before the British resumed control on 30 August 1945. Its population rebounded quickly after

1449-563: A paper on reefs and the formation of atolls as a result of the second voyage of HMS Beagle in 1831–1836. Robert FitzRoy published a four-volume report of Beagle ' s three voyages. In 1841–1842 Edward Forbes undertook dredging in the Aegean Sea that founded marine ecology. The first superintendent of the United States Naval Observatory (1842–1861), Matthew Fontaine Maury devoted his time to

1610-505: A past age." Nothing of the sort came to pass, however; though a few organisms previously regarded as extinct were found and cataloged among the many new discoveries, the harvest was typical of what might be found in exploring any equivalent extent of new territory. Furthermore, in the process of preserving specimens in alcohol , Thomson and chemist John Young Buchanan realized that he had inadvertently debunked Huxley's prior report of Bathybius haeckelii , an acellular protoplasm covering

1771-484: A person with name bearing this character. The second character 港, /hœŋ/, means a branch flow of water body, or a channel for boats to go through. This means the translation to harbour was a modern invention. There were four basic speculations, namely fragrant/incense wood, fragrant river, female pirate named 香, and red incense burner . Not all of them are plausible in face of language, history and geography evidences. The Cantonese name in Chinese character 香港

1932-547: A remote island that was somehow far from the attention of administration and hence lack of documentation or documentation was destroyed easily year by year. The name of Hong Kong comes from Cantonese name 香港, /hœŋ kɔŋ/, in Chinese character. The name commonly translates as "fragrant harbour" or alternatively "incense harbour". The first character 香, /hœŋ/, means any pleasant or sweet smell , namely fragrant , or materials that could produce pleasant smell, usually comes from plants or animals, including incense . But it could

2093-554: A secretary-artist and a photographer. The Royal Society of London obtained the use of Challenger from the Royal Navy and in 1872 modified the ship for scientific tasks at Sheerness , equipping it with separate laboratories for natural history and chemistry . The expedition, led by Captain George Nares , sailed from Portsmouth, England , on 21 December 1872. Other naval officers included Commander John Maclear . Under

2254-531: A series of protests in 2014 which became known as the Umbrella Revolution. Discrepancies in the electoral registry and disqualification of elected legislators after the 2016 Legislative Council elections and enforcement of national law in the West Kowloon high-speed railway station raised further concerns about the region's autonomy. In June 2019, mass protests erupted in response to

2415-674: A ship with the name Challenger should put the seal on the work of that great pioneering expedition of oceanography. The expedition also verified the existence of the Mid-Atlantic Ridge extending from the southern hemisphere to the northern one. Findings from the Challenger expedition continued to be published until 1895, 19 years after the completion of its journey, by the Challenger Office, Edinburgh, established for that purpose. The report contained 50 volumes and

2576-424: A stable environment that evolution would slow or stop entirely. Louis Agassiz believed that in the deeps "we should expect to find representatives of earlier geological periods." Thomas Huxley stated that he expected to see " zoological antiquities which in the tranquil and little changed depths of the ocean have escaped the causes of destruction at work in the shallows and represent the predominant population of

2737-410: A variety of dredges and trawls to collect biological samples. The dredges consisted of metal nets attached to a wooden plank and dragged across the sea floor. Mop heads attached to the wooden plank would sweep across the sea floor and release organisms from the ocean bottom to be caught in the nets. Trawls were large metal nets towed behind the ship to collect organisms at different depths of water. Upon

2898-625: A voyage around the Cape of Good Hope in 1777, he mapped "the banks and currents at the Lagullas " . He was also the first to understand the nature of the intermittent current near the Isles of Scilly , (now known as Rennell's Current). The tides and currents of the ocean are distinct. Tides are the rise and fall of sea levels created by the combination of the gravitational forces of the Moon along with

3059-424: A wide range of disciplines to deepen their understanding of the world’s oceans, incorporating insights from astronomy , biology , chemistry , geography , geology , hydrology , meteorology and physics . Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations on tides were recorded by Aristotle and Strabo in 384–322 BC. Early exploration of

3220-431: Is a special administrative region of China , with executive, legislative, and judicial powers devolved from the national government . The Sino-British Joint Declaration provided for economic and administrative continuity through the handover, resulting in an executive-led governing system largely inherited from the territory's history as a British colony. Under these terms and the "one country, two systems" principle,

3381-651: Is due to the change in the regime of winds and currents: the North Atlantic gyre and the Equatorial counter current will push south along the northwest bulge of Africa, while the uncertain winds where the Northeast trades meet the Southeast trades (the doldrums) leave a sailing ship to the mercy of the currents. Together, prevalent current and wind make northwards progress very difficult or impossible. It

3542-468: Is generally believed to be an early phonetic rendering of the Cantonese (or Tanka Cantonese ) of characters 香港. Sir John Davis , the second colonial governor, offered an alternative origin; Davis said that the name derived from "Hoong-keang" ("red torrent"), reflecting the colour of soil over which a waterfall on the island flowed. The simplified name Hong Kong was frequently used by 1810. The name

3703-410: Is governed by a hybrid regime that is not fully representative of the population. Legislative Council members elected by functional constituencies composed of professional and special interest groups are accountable to these narrow corporate electorates and not the general public. This electoral arrangement has guaranteed a pro-Beijing camp majority in the legislature since the handover. Similarly,

3864-717: Is likely to affect marine organisms with calcareous shells, such as oysters, clams, sea urchins and corals, and the carbonate compensation depth will rise closer to the sea surface. Affected planktonic organisms will include pteropods , coccolithophorids and foraminifera , all important in the food chain . In tropical regions, corals are likely to be severely affected as they become less able to build their calcium carbonate skeletons, in turn adversely impacting other reef dwellers. The current rate of ocean chemistry change seems to be unprecedented in Earth's geological history, making it unclear how well marine ecosystems will adapt to

4025-549: Is remembered in the navigation context for the determination of the loxodromic curve: the shortest course between two points on the surface of a sphere represented onto a two-dimensional map. When he published his "Treatise of the Sphere" (1537), mostly a commentated translation of earlier work by others, he included a treatise on geometrical and astronomic methods of navigation. There he states clearly that Portuguese navigations were not an adventurous endeavour: "nam se fezeram indo

4186-444: Is the scientific study of the ocean , including its physics , chemistry , biology , and geology . It is an Earth science , which covers a wide range of topics, including ocean currents , waves , and geophysical fluid dynamics ; fluxes of various chemical substances and physical properties within the ocean and across its boundaries; ecosystem dynamics; and plate tectonics and seabed geology. Oceanographers draw upon

4347-705: The Challenger expedition . Challenger , leased from the Royal Navy, was modified for scientific work and equipped with separate laboratories for natural history and chemistry . Under the scientific supervision of Thomson, Challenger travelled nearly 70,000 nautical miles (130,000 km) surveying and exploring. On her journey circumnavigating the globe, 492 deep sea soundings, 133 bottom dredges, 151 open water trawls and 263 serial water temperature observations were taken. Around 4,700 new species of marine life were discovered. The result

4508-709: The Australian Institute of Marine Science (AIMS), established in 1972 soon became a key player in marine tropical research. In 1921 the International Hydrographic Bureau , called since 1970 the International Hydrographic Organization , was established to develop hydrographic and nautical charting standards. Hong Kong Hong Kong is a special administrative region of China . With 7.4 million residents of various nationalities in

4669-542: The Basic Law of Hong Kong for 50 years after the handover. It does not specify how Hong Kong will be governed after 2047, and the central government's role in determining the territory's future system of government is the subject of political debate and speculation. Hong Kong's political and judicial systems may be integrated with China's at that time, or the territory may continue to be administered separately. However, in response to large-scale protests in 2019 and 2020 ,

4830-591: The Basic Law of Hong Kong is the regional constitution. The regional government is composed of three branches: The chief executive is the head of government and serves for a maximum of two five-year terms. The State Council (led by the Premier of China ) appoints the chief executive after nomination by the Election Committee , which is composed of 1500 business, community, and government leaders. The Legislative Council has 90 members, each serving

4991-604: The Chinese People's Political Consultative Conference appointed by the central government. Chinese national law does not generally apply in the region, and Hong Kong is treated as a separate jurisdiction. Its judicial system is based on common law , continuing the legal tradition established during British rule. Local courts may refer to precedents set in English law and overseas jurisprudence. However, mainland criminal procedure law applies to cases investigated by

5152-563: The Chinese central government 's adherence to the "one country, two systems" principle. After reversal of the last colonial era Legislative Council democratic reforms following the handover, the regional government unsuccessfully attempted to enact national security legislation pursuant to Article 23 of the Basic Law . The central government decision to implement nominee pre-screening before allowing chief executive elections triggered

5313-779: The Ishiguro Storm Surge Computer ) generally now replaced by numerical methods (e.g. SLOSH .) An oceanographic buoy array was established in the Pacific to allow prediction of El Niño events. 1990 saw the start of the World Ocean Circulation Experiment (WOCE) which continued until 2002. Geosat seafloor mapping data became available in 1995. Study of the oceans is critical to understanding shifts in Earth's energy balance along with related global and regional changes in climate ,

5474-1169: The Mediterranean Science Commission . Marine research institutes were already in existence, starting with the Stazione Zoologica Anton Dohrn in Naples, Italy (1872), the Biological Station of Roscoff, France (1876), the Arago Laboratory in Banyuls-sur-mer, France (1882), the Laboratory of the Marine Biological Association in Plymouth, UK (1884), the Norwegian Institute for Marine Research in Bergen, Norway (1900),

5635-734: The Office for Safeguarding National Security of the CPG in the HKSAR . Interpretative and amending power over the Basic Law and jurisdiction over acts of state lie with the central authority, making regional courts ultimately subordinate to the mainland's socialist civil law system. Decisions made by the Standing Committee of the National People's Congress override any territorial judicial process. Furthermore, in circumstances where

5796-670: The Paleolithic period. The claim is based on an archaeological investigation in Wong Tei Tung , Sai Kung in 2003. The archaeological works revealed knapped stone tools from deposits that were dated using optical luminescence dating . During the Middle Neolithic period, about 6,000 years ago, the region had been widely occupied by humans. Neolithic to Bronze Age Hong Kong settlers were semi-coastal people. Early inhabitants are believed to be Austronesians in

5957-717: The People's Liberation Army is responsible for the region's defence. Although the Chairman of the Central Military Commission is supreme commander of the armed forces, the regional government may request assistance from the garrison. Hong Kong residents are not required to perform military service, and current law has no provision for local enlistment, so its defence is composed entirely of non-Hongkongers. The central government and Ministry of Foreign Affairs handle diplomatic matters, but Hong Kong retains

6118-595: The Safeguarding National Security Ordinance was passed by the Legislative Council to grant officials "even more powers to crack down on opposition to Beijing and the Hong Kong government" and includes penalties such as life imprisonment for political crimes such as treason and insurrection . Critics state that this expansion "will strike a lasting blow to the partial autonomy the city had been promised by China [in

6279-502: The Sino-British Joint Declaration ]." Hong Kong's administrative divisions are divided into three levels: Areas (區域), Districts (地區), and Sub-districts (分區). Hong Kong is administratively divided into three areas: Hong Kong Island , Kowloon , and the New Territories . They are further divided into 18 districts. The area of Hong Kong Island has four districts, the area of Kowloon has five districts, and

6440-457: The Standing Committee of the National People's Congress passed the controversial Hong Kong national security law . The law criminalises secession, subversion, terrorism and collusion with foreign elements and establishes the Office for Safeguarding National Security of the CPG in the HKSAR, an investigative office under Central People's Government authority immune from HKSAR jurisdiction. Some of

6601-560: The biosphere and biogeochemistry . The atmosphere and ocean are linked because of evaporation and precipitation as well as thermal flux (and solar insolation ). Recent studies have advanced knowledge on ocean acidification , ocean heat content , ocean currents , sea level rise , the oceanic carbon cycle , the water cycle , Arctic sea ice decline , coral bleaching , marine heatwaves , extreme weather , coastal erosion and many other phenomena in regards to ongoing climate change and climate feedbacks . In general, understanding

6762-617: The central government in Beijing in June 2020 resulted in the suspension of bilateral extradition treaties by the United Kingdom, Canada, Australia, New Zealand, Finland, and Ireland. The United States ended its preferential economic and trade treatment of Hong Kong in July 2020 because it was no longer able to distinguish Hong Kong as a separate entity from the People's Republic of China. In 2024,

6923-467: The 1860s and 1870s and their efficient laying and operation were matters of great strategic and commercial importance. At each of the 360 stations the crew measured the bottom depth and temperature at different depths, observed weather and surface ocean conditions, and collected seafloor, water, and biota samples. Challenger 's crew used methods that were developed in prior small-scale expeditions to make observations. To measure depth, they would lower

7084-481: The 29 days Cabral took from Cape Verde up to landing in Monte Pascoal , Brazil. The Danish expedition to Arabia 1761–67 can be said to be the world's first oceanographic expedition, as the ship Grønland had on board a group of scientists, including naturalist Peter Forsskål , who was assigned an explicit task by the king, Frederik V , to study and describe the marine life in the open sea, including finding

7245-655: The Azores), bringing what is now Brazil into the Portuguese area of domination. The knowledge gathered from open sea exploration allowed for the well-documented extended periods of sail without sight of land, not by accident but as pre-determined planned route; for example, 30 days for Bartolomeu Dias culminating on Mossel Bay , the three months Gama spent in the South Atlantic to use the Brazil current (southward), or

7406-739: The Cape of Good Hope to the parallel of 60 degrees south . The islands visited during this period were the Prince Edward Islands , the Crozet Islands , the Kerguelen Islands , and Heard Island . February 1874 was spent travelling south and then generally eastwards in the vicinity of the Antarctic Circle , with sightings of icebergs, pack ice and whales. The route then took the ship north-eastward and away from

7567-656: The Gulf Stream's cause. Franklin and Timothy Folger printed the first map of the Gulf Stream in 1769–1770. Information on the currents of the Pacific Ocean was gathered by explorers of the late 18th century, including James Cook and Louis Antoine de Bougainville . James Rennell wrote the first scientific textbooks on oceanography, detailing the current flows of the Atlantic and Indian oceans. During

Hung-heung-lo , 紅香爐, red incense burner, was a station of Ch'ing Dynasty coastal defense. The name once used to refer the whole Hong Kong Island after the station was established. It was too late to be the etymology of Hong Kong. Some points fragrant to

7889-857: The Laboratory für internationale Meeresforschung, Kiel, Germany (1902). On the other side of the Atlantic, the Scripps Institution of Oceanography was founded in 1903, followed by the Woods Hole Oceanographic Institution in 1930, the Virginia Institute of Marine Science in 1938, the Lamont–Doherty Earth Observatory at Columbia University in 1949, and later the School of Oceanography at University of Washington . In Australia ,

8050-406: The Legislative Council and the requirement that all candidates be vetted and approved by a Beijing-appointed Candidate Eligibility Review Committee . In May 2023, the Legislative Council also introduced legislation to reduce the number of directly elected seats in the district councils, and a District Council Eligibility Review Committee was similarly established to vet candidates. Hong Kong

8211-548: The Legislative Council in the 2016 election . These parties have aligned themselves into three ideological groups: the pro-Beijing camp (the current government), the pro-democracy camp , and localist groups . The Chinese Communist Party does not have an official political presence in Hong Kong, and its members do not run in local elections. Hong Kong is represented in the National People's Congress by 36 deputies chosen through an electoral college and 203 delegates in

8372-618: The Legislative Council passed the National Anthem Ordinance , which criminalised "insults to the national anthem of China". The Chinese central government meanwhile enacted the Hong Kong national security law to help quell protests in the region. Nine months later, in March 2021, the Chinese central government introduced amendments to Hong Kong's electoral system , which included the reduction of directly elected seats in

8533-419: The Middle Neolithic period and later the Yue people. As hinted by the archaeological works in Sha Ha, Sai Kung, rice cultivation had been introduced since Late Neolithic period. Bronze Age Hong Kong featured coarse pottery, hard pottery, quartz and stone jewelry, as well as small bronze implements. The Qin dynasty incorporated the Hong Kong area into China for the first time in 214 BCE, after conquering

8694-438: The New Territories. Much of this is built on reclaimed land ; 70 km (27 sq mi) (6% of the total land or about 25% of developed space in the territory) is reclaimed from the sea. Undeveloped terrain is hilly to mountainous, with very little flat land, and consists mostly of grassland, woodland, shrubland, or farmland. About 40% of the remaining land area is country parks and nature reserves. The territory has

8855-484: The North America and West Indies Station), east to the Azores , back to Madeira, and then south to the Cape Verde Islands . During this period, there was a detour in April and May 1873, sailing from Bermuda north to Halifax and back, crossing the Gulf Stream twice with the reverse journey crossing further to the east. After leaving the Cape Verde Islands in August 1873, the expedition initially sailed south-east and then headed west to reach St Paul's Rocks . From here,

9016-427: The Pacific to a point due north of the Sandwich Islands (Hawaiʻi), and then turning south, making landfall at the end of July at Honolulu on the Hawaiian island of Oʻahu . A couple of weeks later, in mid-August, the ship departed south-eastward, anchoring at Hilo Bay off Hawaiʻi Island , before continuing to the south and reaching Tahiti in mid-September. The expedition left Tahiti in early October, swinging to

9177-483: The Pacific, past the Juan Fernández Islands, before turning to the south-east and back towards South America, reaching Port Otway in the Gulf of Penas on 31 December 1875. Most of January 1876 was spent navigating around the southern tip of South America, surveying and touching at many of the bays and islands of the Patagonian archipelago, the Strait of Magellan , and Tierra del Fuego . Locations visited here include Hale Cove, Gray Harbour, Port Grappler, Tom Bay, all in

9338-418: The Philippines and Indonesia, have little protection under regional law. Although they live and work in Hong Kong, these workers are not treated as ordinary residents and do not have the right of abode in the territory. Sex trafficking is also an issue, local, mainland Chinese, and foreign women have been trafficked for sex in brothels , homes, and businesses in the city. The Joint Declaration guarantees

9499-406: The Standing Committee declares a state of emergency in Hong Kong, the State Council may enforce national law in the region. The territory's jurisdictional independence is most apparent in its immigration and taxation policies. The Immigration Department issues passports for permanent residents which differ from those of the mainland or Macau, and the region maintains a regulated border with

9660-457: The Sun (the Sun just in a much lesser extent) and are also caused by the Earth and Moon orbiting each other. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect , breaking waves , cabbeling , and temperature and salinity differences . Sir James Clark Ross took the first modern sounding in deep sea in 1840, and Charles Darwin published

9821-445: The Yuan Dynasty. By the end of the Yuan dynasty , seven large families had settled in the region and owned most of the land. Settlers from nearby provinces migrated to Kowloon throughout the Ming dynasty . The earliest European visitor was Portuguese explorer Jorge Álvares , who arrived in 1513. Portuguese merchants established a trading post called Tamão in Hong Kong waters and began regular trade with southern China. Although

9982-435: The ability to maintain separate economic and cultural relations with foreign nations . The territory actively participates in the World Trade Organization , the Asia-Pacific Economic Cooperation forum, the International Olympic Committee , and many United Nations agencies. The regional government maintains trade offices in Greater China and other nations. The imposition of the Hong Kong national security law by

10143-402: The aforementioned acts were previously considered protected speech under Hong Kong law. The United Kingdom considers the law to be a serious violation of the Joint Declaration. In October 2020, the Hong Kong Police arrested seven pro- democracy politicians over tussles with pro-Beijing politicians in the Legislative Council in May. They were charged with contempt and interfering with members of

10304-505: The agreement. After more than a year of further hostilities, Hong Kong Island was formally ceded to the United Kingdom in the 1842 Treaty of Nanking . Administrative infrastructure was quickly built by early 1842, but piracy, disease, and hostile Qing policies initially prevented the government from attracting commerce. Conditions on the island improved during the Taiping Rebellion in the 1850s, when many Chinese refugees, including wealthy merchants, fled mainland turbulence and settled in

10465-399: The area of the New Territories has nine districts. Each district is represented by a district council . The district councils advise the government on local issues such as public facility provisioning, community programme maintenance, cultural promotion, and environmental policy. As of 2024, there are a total of 470 district council seats, 88 of which are directly elected. In May 2023,

10626-496: The cause of mareel , or milky seas. For this purpose, the expedition was equipped with nets and scrapers, specifically designed to collect samples from the open waters and the bottom at great depth. Although Juan Ponce de León in 1513 first identified the Gulf Stream , and the current was well known to mariners, Benjamin Franklin made the first scientific study of it and gave it its name. Franklin measured water temperatures during several Atlantic crossings and correctly explained

10787-573: The centre for oceanographic research well into the 20th century. Murray was the first to study marine trenches and in particular the Mid-Atlantic Ridge , and map the sedimentary deposits in the oceans. He tried to map out the world's ocean currents based on salinity and temperature observations, and was the first to correctly understand the nature of coral reef development. In the late 19th century, other Western nations also sent out scientific expeditions (as did private individuals and institutions). The first purpose-built oceanographic ship, Albatros ,

10948-1041: The chief executive is selected by establishment politicians and corporate members of the Election Committee rather than directly elected. Despite universal suffrage being established as ultimate goals for the election of the chief executive and all members of the Legislative Council in Articles 45 and 68 of the basic law, the legislature is only partially directly elected, and the executive continues to be nominated by an unrepresentative body. The government has been repeatedly petitioned to introduce direct elections for these positions, but has not introduced these direct elections as of 2024. Ethnic minorities (except those of European ancestry) have marginal representation in government and often experience discrimination in housing, education, and employment. Employment vacancies and public service appointments frequently have language requirements which minority job seekers do not meet, and language education resources remain inadequate for Chinese learners. Foreign domestic helpers , mostly women from

11109-511: The colony. Further tensions between the British and Qing over the opium trade escalated into the Second Opium War . The Qing were again defeated and forced to give up Kowloon Peninsula and Stonecutters Island in the Convention of Peking . By the end of this war, Hong Kong had evolved from a transient colonial outpost into a major entrepôt . Rapid economic improvement during the 1850s attracted foreign investment, as potential stakeholders became more confident in Hong Kong's future. The colony

11270-434: The composition of seawater. Murray and Alphonse François Renard mapped oceanic sediments. Thomson believed, as did many adherents of the then-recent theory of evolution , that the deep sea would be home to " living fossils " long extinct in shallower waters, examples of " missing links ". They believed that the conditions of constant cold temperature, darkness, and lack of currents, waves, or seismic events provided such

11431-460: The context of the physical, chemical and geological characteristics of their ocean environment. Chemical oceanography is the study of the chemistry of the ocean. Whereas chemical oceanography is primarily occupied with the study and understanding of seawater properties and its changes, ocean chemistry focuses primarily on the geochemical cycles . The following is a central topic investigated by chemical oceanography. Ocean acidification describes

11592-511: The cosmographers would provide (...) and they took charts with exact routes and no longer those used by the ancient). His credibility rests on being personally involved in the instruction of pilots and senior seafarers from 1527 onwards by Royal appointment, along with his recognized competence as mathematician and astronomer. The main problem in navigating back from the south of the Canary Islands (or south of Boujdour ) by sail alone,

11753-590: The council, while none of the pro-Beijing lawmakers were detained. Annual commemorations of the 1989 Tiananmen Square protests and massacre were also cancelled amidst fears of violating the national security law. In March 2021, the Chinese central government unilaterally changed Hong Kong's electoral system and established the Candidate Eligibility Review Committee , which would be tasked with screening and evaluating political candidates for their "patriotism", effectively crushing

11914-542: The currents and winds of the Atlantic, is demonstrated by the understanding of the seasonal variations, with expeditions setting sail at different times of the year taking different routes to take account of seasonal predominate winds. This happens from as early as late 15th century and early 16th: Bartolomeu Dias followed the African coast on his way south in August 1487, while Vasco da Gama would take an open sea route from

12075-456: The decade long period between Bartolomeu Dias finding the southern tip of Africa, and Gama's departure; additionally, there are indications of further travels by Bartolomeu Dias in the area. The most significant consequence of this systematic knowledge was the negotiation of the Treaty of Tordesillas in 1494, moving the line of demarcation 270 leagues to the west (from 100 to 370 leagues west of

12236-406: The decrease in ocean pH that is caused by anthropogenic carbon dioxide (CO 2 ) emissions into the atmosphere . Seawater is slightly alkaline and had a preindustrial pH of about 8.2. More recently, anthropogenic activities have steadily increased the carbon dioxide content of the atmosphere; about 30–40% of the added CO 2 is absorbed by the oceans, forming carbonic acid and lowering

12397-547: The depression, the Challenger Deep , now bears the name of the vessel and its successor, HMS Challenger II , which in 1951 identified a depth of 5,944 fathoms nearby. Thomas Gaskell , the Chief Scientist on HMS Challenger II, observed that the later measurement was not more than 50 miles from the spot where the nineteenth-century Challenger found her deepest depth [...] and it may be thought fitting that

12558-615: The depths, 15 of Challenger 's 17 guns were removed and its spars reduced to make more space available. Laboratories, extra cabins and a special dredging platform were installed. Challenger used mainly sail power during the expedition; the steam engine was used only for dragging the dredge, station-keeping while taking soundings, and entering and leaving ports. It was loaded with specimen jars, filled with alcohol for preservation of samples, microscopes and chemical apparatus, trawls and dredges, thermometers, barometers, water sampling bottles, sounding leads , devices to collect sediment from

12719-460: The end of August and thence arriving at Cape York, at the tip of Australia's Cape York Peninsula . Over the following three months, from September to November 1874, the expedition visited several islands and island groups while sailing from Cape York to China and Hong Kong (then a British colony ). The first part of the route passed north and west over the Arafura Sea , with New Guinea to

12880-548: The end of August. The ship arrived in New Zealand in late June and left in early July. Before reaching Wellington (on New Zealand's North Island), brief stops were made at Port Hardy (on d'Urville Island ) and Queen Charlotte Sound and Challenger passed through the Cook Strait to reach Wellington. The route from Wellington to Tonga went along the east coast of New Zealand's North Island, and then north and east into

13041-550: The end of February, heading first due east and then due north, arriving at Ascension Island at the end of March 1876. The period from early- to mid-April was spent sailing from Ascension Island to the Cape Verde Islands. From here, the route taken in late April and early May 1876 was a westward loop to the north out into the mid-Atlantic, eventually turning due east towards Europe to touch land at Vigo in Spain towards

13202-526: The end of May. The final stage of the voyage took the ship and its crew north-eastward from Vigo, skirting the Bay of Biscay to make landfall in England. Challenger returned to Spithead , Hampshire , on 24 May 1876, having spent 713 days out of the intervening 1,250 at sea. The Royal Society stated the voyage's scientific goals were: One of the goals of the physical measurements for HMS Challenger

13363-469: The end of the New Territories lease approached, and Governor Murray MacLehose raised the question of Hong Kong's status with Deng Xiaoping in 1979. Diplomatic negotiations with China resulted in the 1984 Sino-British Joint Declaration , in which the United Kingdom agreed to the handover of the colony in 1997 and China would guarantee Hong Kong's economic and political systems for 50 years after

13524-532: The expedition departed in early January 1875 to retrace their route south-east towards New Guinea. The first stop on this outward leg of the journey was Manila. From there, they continued on to Samboangan, but took a different route through the interior of the Philippines, this time touching at the island of Zebu . From Samboangan the ship diverged from the inward route, this time passing south of Mindanao—in early-February 1875. Challenger then headed east into

13685-567: The extra heat stored in the ocean from changes in Earth's energy balance . The increase in the ocean heat play an important role in sea level rise , because of thermal expansion . Ocean warming accounts for 90% of the energy accumulation associated with global warming since 1971. Paleoceanography is the study of the history of the oceans in the geologic past with regard to circulation, chemistry, biology, geology and patterns of sedimentation and biological productivity. Paleoceanographic studies using environment models and different proxies enable

13846-433: The first all-woman oceanographic expedition. Until that time, gender policies restricted women oceanographers from participating in voyages to a significant extent. From the 1970s, there has been much emphasis on the application of large scale computers to oceanography to allow numerical predictions of ocean conditions and as a part of overall environmental change prediction. Early techniques included analog computers (such as

14007-485: The first woman to have earned a PhD (at Scripps) in the United States, completed a major work on diatoms that remained the standard taxonomy in the field until well after her death in 1999. In 1940, Cupp was let go from her position at Scripps. Sverdrup specifically commended Cupp as a conscientious and industrious worker and commented that his decision was no reflection on her ability as a scientist. Sverdrup used

14168-572: The government proposed reforms to the District Council electoral system which further cut the number of directly elected seats from 452 to 88, and total seats from 479 to 470. A requirement that district council candidates be vetted and approved by the District Council Eligibility Review Committee was also proposed. The Legislative Council approved the reforms in July 2023. Hong Kong

14329-418: The handover. The impending handover triggered a wave of mass emigration as residents feared an erosion of civil rights, the rule of law, and quality of life. Over half a million people left the territory during the peak migration period, from 1987 to 1996. The Legislative Council became a fully elected legislature for the first time in 1995 and extensively expanded its functions and organisations throughout

14490-585: The ice regions in March 1874, with the expedition reaching Melbourne in Australia later that month. The journey eastward along the coast from Melbourne to Sydney took place in April 1874, passing by Wilsons Promontory and Cape Howe . When the voyage resumed in June 1874, the route went east from Sydney to Wellington in New Zealand, followed by a large loop north into the Pacific calling at Tonga and Fiji , and then back westward to Cape York in Australia by

14651-732: The indigenous Baiyue . The region was consolidated under the Nanyue kingdom (a predecessor state of Vietnam ) after the Qin collapse and recaptured by China after the Han conquest . During the Mongol conquest of China in the 13th century, the Southern Song court was briefly located in modern-day Kowloon City (the Sung Wong Toi site) before its final defeat in the 1279 Battle of Yamen by

14812-400: The instructor billet vacated by Cupp to employ Marston Sargent, a biologist studying marine algae, which was not a new research program at Scripps. Financial pressures did not prevent Sverdrup from retaining the services of two other young post-doctoral students, Walter Munk and Roger Revelle . Cupp's partner, Dorothy Rosenbury, found her a position teaching high school, where she remained for

14973-416: The instrument traveled. Several of these thermometers would be lowered at various depths for recording. However, this design assumed that the water closer to the surface of the ocean was always warmer than that below. During the voyage, Challenger ' s crew tested the reversing thermometer , which could measure temperature at specified depths. Afterwards, this type of thermometer was used extensively until

15134-401: The last years of the colonial rule. The handover of Hong Kong to China was at midnight on 1 July 1997, after 156 years of British rule. Immediately after the handover, Hong Kong was severely affected by several crises. The Hong Kong government was forced to use substantial foreign exchange reserves to maintain the Hong Kong dollar's currency peg during the 1997 Asian financial crisis , and

15295-486: The latitude of Sierra Leone , spending three months in the open sea of the South Atlantic to profit from the southwards deflection of the southwesterly on the Brazilian side (and the Brazilian current going southward - Gama departed in July 1497); and Pedro Álvares Cabral (departing March 1500) took an even larger arch to the west, from the latitude of Cape Verde, thus avoiding the summer monsoon (which would have blocked

15456-478: The main factors determining ocean currents. The thermohaline circulation (THC) ( thermo- referring to temperature and -haline referring to salt content ) connects the ocean basins and is primarily dependent on the density of sea water . It is becoming more common to refer to this system as the 'meridional overturning circulation' because it more accurately accounts for other driving factors beyond temperature and salinity. Oceanic heat content (OHC) refers to

15617-536: The maritime area is included) consists of Hong Kong Island , the Kowloon Peninsula , the New Territories , Lantau Island , and over 200 other islands. Of the total area, 1,073 km (414 sq mi) is land and 35 km (14 sq mi) is water. The territory's highest point is Tai Mo Shan , 957 metres (3,140 ft) above sea level. Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout

15778-551: The material brought back from the expedition including the paleontologist Gabriel Warton Lee . George Albert Boulenger , herpetologist at the Natural History Museum, named a species of lizard, Saproscincus challengeri , after Challenger . Before the Challenger expedition, oceanography had been mainly speculative. As the first true oceanographic cruise, the Challenger expedition laid the groundwork for an entire academic and research discipline. " Challenger "

15939-639: The name of Hong Kong was referring to Aberdeen Channel associating with once flourishing incense industry in Ming Dynasty. It could be where the incense was manufactured, stored or exported but there are no evidences to support it. Another speculation is that "fragrant" may refer to the sweet taste of the harbour's freshwater influx from the Pearl River. It is very unlikely the etymology relating to fragrant river. The whole territories of Hong Kong are surrounded by sea, namely salt water. Aberdeen Channel

16100-729: The north-east and the Australian mainland to the south-west. The first islands visited were the Aru Islands , followed by the nearby Kai Islands . The ship then crossed the Banda Sea touching at the Banda Islands , to reach Amboina ( Ambon Island ) in October 1874, and then continuing to Ternate Island . At the time, all these islands were part of Netherlands East-Indies and are since 1949 part of Indonesia . From Ternate,

16261-520: The northern latitudes where the westerly winds will bring the seafarers towards the western coasts of Europe. The secrecy involving the Portuguese navigations, with the death penalty for the leaking of maps and routes, concentrated all sensitive records in the Royal Archives, completely destroyed by the Lisbon earthquake of 1775 . However, the systematic nature of the Portuguese campaign, mapping

16422-535: The ocean's physical attributes including temperature-salinity structure, mixing, surface waves , internal waves, surface tides , internal tides , and currents . The following are central topics investigated by physical oceanography. Since the early ocean expeditions in oceanography, a major interest was the study of ocean currents and temperature measurements. The tides , the Coriolis effect , changes in direction and strength of wind , salinity, and temperature are

16583-412: The oceans was primarily for cartography and mainly limited to its surfaces and of the animals that fishermen brought up in nets, though depth soundings by lead line were taken. The Portuguese campaign of Atlantic navigation is the earliest example of a systematic scientific large project, sustained over many decades, studying the currents and winds of the Atlantic. The work of Pedro Nunes (1502–1578)

16744-743: The officers was Thomas Henry Tizard , who had carried out important hydrographic observations on previous voyages. Though he was not among the civilian scientific staff, Tizard would later help write the official account of the expedition, and also become a Fellow of the Royal Society . The original ship's complement included 21 officers and around 216 crew members. By the end of the voyage, this had been reduced to 144 due to deaths, desertions, personnel being left ashore due to illness, and planned departures. Challenger reached Hong Kong in December 1874, at which point Nares and Aldrich left

16905-712: The open Pacific, passing by the Kermadec Islands en route to Tongatabu , the main island of the Tonga archipelago (then known as the Friendly Islands). The waters around the Fijian islands, a short distance to the north-west of Tonga, were surveyed during late July and early August 1874. The ship's course was then set westward, reaching Raine Island —on the outer edge of the Great Barrier Reef —at

17066-789: The open sea, before turning to the south-east and making landfall at Humboldt Bay (now Yos Sudarso Bay ) on the north coast of New Guinea. By March 1875, the expedition had reached the Admiralty Islands north-east of New Guinea. The final stage of the voyage on this side of the Pacific was a long journey across the open ocean to the north, passing mostly west of the Caroline Islands and the Mariana Islands , reaching port in Yokohama , Japan, in April 1875. Challenger departed Japan in mid-June 1875, heading east across

17227-484: The opium trade. The commissioner destroyed opium stockpiles and halted all foreign trade, triggering a British military response and the First Opium War . The Qing surrendered early in the war and ceded Hong Kong Island in the Convention of Chuenpi . British forces began controlling Hong Kong shortly after the signing of the convention, from 26 January 1841. However, both countries were dissatisfied and did not ratify

17388-402: The pH (now below 8.1 ) through ocean acidification. The pH is expected to reach 7.7 by the year 2100. An important element for the skeletons of marine animals is calcium , but calcium carbonate becomes more soluble with pressure, so carbonate shells and skeletons dissolve below the carbonate compensation depth . Calcium carbonate becomes more soluble at lower pH, so ocean acidification

17549-705: The polar regions and Africa , so too did the mysteries of the unexplored oceans. The seminal event in the founding of the modern science of oceanography was the 1872–1876 Challenger expedition . As the first true oceanographic cruise, this expedition laid the groundwork for an entire academic and research discipline. In response to a recommendation from the Royal Society , the British Government announced in 1871 an expedition to explore world's oceans and conduct appropriate scientific investigation. Charles Wyville Thomson and Sir John Murray launched

17710-440: The post-war decades to provide safer housing, integrity in the civil service, and more reliable transportation. Nevertheless, widespread public discontent resulted in multiple protests from the 1950s to 1980s, including pro- Republic of China and pro- Chinese Communist Party protests. In the 1967 Hong Kong riots , pro- PRC protestors clashed with the British colonial government. As many as 51 were killed and 802 were injured in

17871-527: The publication, described the report as "the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries". The report is available online as the Report of the Voyage of HMS Challenger . Challenger sailed close to Antarctica , but not within sight of it. However, it was the first scientific expedition to take pictures of icebergs. To enable it to probe

18032-476: The recovery from this was muted by an H5N1 avian-flu outbreak and a housing surplus. This was followed by the 2003 SARS epidemic , during which the territory experienced its most serious economic downturn. Chinese communists portrayed the return of Hong Kong as key moment in the PRC's rise to great power status. Political debates after the handover have centred around the region's democratic development and

18193-543: The region into a wasteland. The Kangxi Emperor lifted the maritime trade prohibition, allowing foreigners to enter Chinese ports in 1684. Qing authorities established the Canton System in 1757 to regulate trade more strictly, restricting non-Russian ships to the port of Canton . Although European demand for Chinese commodities like tea, silk, and porcelain was high, Chinese interest in European manufactured goods

18354-731: The remainder of the Pro-Democracy camp . Hong Kong is on China's southern coast, 60 km (37 mi) east of Macau, on the east side of the mouth of the Pearl River estuary . It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River . The territory's 1,110.18 km (428.64 sq mi) area (2,754.97 km if

18515-474: The rest of her career. (Russell, 2000) Sverdrup, Johnson and Fleming published The Oceans in 1942, which was a major landmark. The Sea (in three volumes, covering physical oceanography, seawater and geology) edited by M.N. Hill was published in 1962, while Rhodes Fairbridge 's Encyclopedia of Oceanography was published in 1966. The Great Global Rift, running along the Mid Atlantic Ridge,

18676-412: The rest of the country. All travellers between Hong Kong and China and Macau must pass through border controls, regardless of nationality. Mainland Chinese citizens do not have right of abode in Hong Kong and are subject to immigration controls. Public finances are handled separately from the national government; taxes levied in Hong Kong do not fund the central authority. The Hong Kong Garrison of

18837-469: The retrieval of a dredge or trawl, Challenger crew would sort, rinse, and store the specimens for examination upon return. The specimens were often preserved in either brine or alcohol. The primary thermometer used throughout the Challenger expedition was the Miller–Casella thermometer , which contained two markers within a curved mercury tube to record the maximum and minimum temperature through which

18998-523: The return route from the western coast of Africa (sequentially called 'volta de Guiné' and 'volta da Mina'); and the references to the Sargasso Sea (also called at the time 'Mar da Baga'), to the west of the Azores , in 1436, reveals the western extent of the return route. This is necessary, under sail, to make use of the southeasterly and northeasterly winds away from the western coast of Africa, up to

19159-410: The route taken by Gama at the time he set sail). Furthermore, there were systematic expeditions pushing into the western Northern Atlantic (Teive, 1454; Vogado, 1462; Teles, 1474; Ulmo, 1486). The documents relating to the supplying of ships, and the ordering of sun declination tables for the southern Atlantic for as early as 1493–1496, all suggest a well-planned and systematic activity happening during

19320-578: The route went north-westward towards the Philippines, passing east of Celebes ( Sulawesi ) into the Celebes Sea . The expedition called at Samboangan ( Zamboanga ) on Mindanao, and then Iloilo on the island of Panay, before navigating within the interior of the archipelago en route to the bay and harbour of Manila on the island of Luzon. The crossing north-westward from Manila to Hong Kong took place in November 1874. After several weeks in Hong Kong,

19481-404: The route went south across the equator to Fernando de Noronha during September 1873, and onwards that same month to Bahia (now called Salvador) in Brazil. The period from September to October 1873 was spent crossing the Atlantic from Bahia to the Cape of Good Hope , touching at Tristan da Cunha on the way. December 1873 to February 1874 was spent sailing on a roughly south-eastern track from

19642-619: The scientific community to assess the role of the oceanic processes in the global climate by the reconstruction of past climate at various intervals. Paleoceanographic research is also intimately tied to palaeoclimatology. The earliest international organizations of oceanography were founded at the turn of the 20th century, starting with the International Council for the Exploration of the Sea created in 1902, followed in 1919 by

19803-540: The scientific supervision of Thomson himself, the ship traveled approximately 68,890 nautical miles (79,280 miles; 127,580 kilometres) surveying and exploring. The result was the Report of the Scientific Results of the Exploring Voyage of H.M.S. Challenger during the years 1873–76 which, among many other discoveries, catalogued over 4,000 previously unknown species. John Murray, who supervised

19964-570: The sea bed and great lengths of rope with which to suspend the equipment into the ocean depths. Because of the novelty of the expedition, some of the equipment was invented or specially modified for the occasion. It carried 181 miles (291 km) of Italian hemp rope for sounding . On its landmark journey circumnavigating the globe, 492 deep sea soundings, 133 bottom dredges, 151 open water trawls and 263 serial water temperature observations were taken. About 4,700 new species of marine life were discovered. The scientific work

20125-464: The sea bottoms, which was purported to be the link between non-living matter and living cells. The net effect was a setback for the proponents of evolution. On 23 March 1875, at sample station number 225 located in the southwest Pacific Ocean between Guam and Palau, the crew recorded a sounding of 4,475 fathoms (26,850 ft; 8,184 m), which was confirmed by a second sounding. As shown by later expeditions using modern equipment, this area represents

20286-560: The second half of the 20th century. After the return of the Challenger, C.W. Thomson asked Peter Tait to solve a thorny and important question: to evaluate the error in the measurement of the temperature of deep waters caused by the high pressures to which the thermometers were subjected. Tait solved this question and continued his work with a more fundamental study on the compressibility of liquids leading to his famous Tait equation . William Dittmar of Glasgow University established

20447-400: The shifting conditions of the near future. Of particular concern is the manner in which the combination of acidification with the expected additional stressors of higher ocean temperatures and lower oxygen levels will impact the seas. Geological oceanography is the study of the geology of the ocean floor including plate tectonics and paleoceanography . Physical oceanography studies

20608-613: The ship from Portsmouth (December 1872) south to Lisbon (January 1873) and then on to Gibraltar . The next stops were Madeira and the Canary Islands (both February 1873). The period from February to July 1873 was spent crossing the Atlantic westwards from the Canary Islands to the Virgin Islands , then heading north to the North Atlantic archipelago and Imperial fortress colony of Bermuda (home base of

20769-552: The ship to take part in the British Arctic Expedition . The new captain was Frank Tourle Thomson. The second-in-command, and the most senior officer present throughout the entire expedition, was Commander John Maclear . Willemoes-Suhm died and was buried at sea on the voyage to Tahiti . Lords Campbell and Balfour left the ship in Valparaiso, Chile, after being promoted. The first leg of the expedition took

20930-407: The shore region was in deprived state. Few people came back to rebuilt the region and the government at that time introduced Hakka migrants to refill the region. New migrants knew nothing about the incense industry and marked its end. From 2000s onward, the remainants of incense trees in Hong Kong were recurrently being chopped down by cross-border illegal loggers. These are strong indicators that

21091-406: The smell of opium, but it is impossible as there was no opium trade in Ming Dynasty. The first romanisation came as "He-Ong-Kong" in 1780, originally referred to a small inlet located between Aberdeen Island and the southern coast of Hong Kong Island. Aberdeen was an initial point of contact between British sailors and local fishermen. Although the source of the romanised name is unknown, it

21252-469: The southern end of the Mariana Trench and is one of the deepest known places on the ocean floor. Modern soundings to 6,012 fathoms (36,070 ft; 10,994 m) have since been found near the site of the Challenger ' s original sounding. Challenger ' s discovery of this depth was a key finding of the expedition in broadening oceanographic knowledge about the ocean's depth and extent;

21413-486: The study of marine meteorology, navigation , and charting prevailing winds and currents. His 1855 textbook Physical Geography of the Sea was one of the first comprehensive oceanography studies. Many nations sent oceanographic observations to Maury at the Naval Observatory, where he and his colleagues evaluated the information and distributed the results worldwide. Knowledge of the oceans remained confined to

21574-530: The submersible DSV  Alvin . In the 1950s, Auguste Piccard invented the bathyscaphe and used the bathyscaphe Trieste to investigate the ocean's depths. The United States nuclear submarine Nautilus made the first journey under the ice to the North Pole in 1958. In 1962 the FLIP (Floating Instrument Platform), a 355-foot (108 m) spar buoy, was first deployed. In 1968, Tanya Atwater led

21735-410: The territory is now one of the world's most significant financial centres and commercial ports. Hong Kong is the world's third-ranked global financial centre (behind New York City and London ), ninth-largest exporter, and eighth-largest importer. Its currency, the Hong Kong dollar , is the ninth most traded currency in the world. Home to the seventh-highest number of billionaires of any city in

21896-566: The time, the American Matthew Fontaine Maury . All these results of physical measurements were synthesized by John James Wild (i.e. the expedition's secretary-artist) in his doctoral thesis at the University of Zurich. A second important issue concerning the collection of different kinds of physical data on the ocean floor was the laying of submarine telegraph cables. Many transoceanic cables were being laid in

22057-400: The topmost few fathoms of the water and a small amount of the bottom, mainly in shallow areas. Almost nothing was known of the ocean depths. The British Royal Navy 's efforts to chart all of the world's coastlines in the mid-19th century reinforced the vague idea that most of the ocean was very deep, although little more was known. As exploration ignited both popular and scientific interest in

22218-525: The traders were expelled after military clashes in the 1520s, Portuguese-Chinese trade relations were re-established by 1549 . Portugal acquired a permanent lease for Macau in 1887. After the Qing conquest , maritime trade was banned under the Haijin policies. From 1661 to 1683, the population of most of the area forming present day Hong Kong was cleared under the Great Clearance , turning

22379-696: The vicinity of Wellington Island ; Puerta Bueno, near Hanover Island ; Isthmus Bay, near the Queen Adelaide Archipelago ; and Port Churruca, near Santa Ines Island . The final stops, before heading out into the Atlantic, were Port Famine , Sandy Point , and Elizabeth Island. Challenger reached the Falkland Islands towards the end of January, calling at Port Stanley and then continuing northward, reaching Montevideo in Uruguay in mid-February 1876. The ship left Montevideo at

22540-440: The village was marked as Little Hong Kong in a map of 1899. Regarding fragrant/incense wood, historian professor Lo Hsiang-lin was the one first exploring the etymology of Hong Kong with incense tree. The whole territory of Hong Kong, being part of Tung Kwun County, once cultivated incense trees, Aquilaria sinensis , in industrial scale during Ming Dynasty. The county incense was known as kwun-heung , 莞香 in character, which

22701-485: The violence, including dozens killed by the Royal Hong Kong Police via beatings and shootings. Although the territory's competitiveness in manufacturing gradually declined because of rising labour and property costs, it transitioned to a service-based economy. By the early 1990s, Hong Kong had established itself as a global financial centre and shipping hub. The colony faced an uncertain future as

22862-756: The war, as skilled Chinese migrants fled from the Chinese Civil War and more refugees crossed the border when the Chinese Communist Party took control of mainland China in 1949. Hong Kong became the first of the Four Asian Tiger economies to industrialise during the 1950s. With a rapidly increasing population, the colonial government attempted reforms to improve infrastructure and public services. The public-housing estate programme , Independent Commission Against Corruption , and Mass Transit Railway were all established during

23023-656: The west and south of the Tubuai Islands and then heading to the south-east before turning east towards the South American coast. The route touched at the Juan Fernández Islands in mid-November 1875, with Challenger reaching the port of Valparaiso in Chile a few days later. The next stage of the journey commenced the following month, with the route taking the ship south-westward back out into

23184-405: The world and currently the only place in Asia to be in the top 5. The city has the highest life expectancy in the world , and a public transport usage exceeding 90 per cent. There is no lack of tales and speculations on the etymology of Hong Kong. It was because the name was mysterious that no longer fitted the environment on the eve of colonisation by the British. It was because the name was on

23345-434: The world ocean through further scientific study enables better stewardship and sustainable utilization of Earth's resources. The Intergovernmental Oceanographic Commission reports that 1.7% of the total national research expenditure of its members is focused on ocean science. The study of oceanography is divided into these five branches: Biological oceanography investigates the ecology and biology of marine organisms in

23506-454: The world, Hong Kong has the largest number of ultra high-net-worth individuals . Although the city has one of the highest per capita incomes in the world, severe income inequality exists among the population. Despite being the city with the most skyscrapers in the world , housing in Hong Kong is consistently in high demand . Hong Kong is a highly developed territory and has a Human Development Index (HDI) of 0.956, ranking fourth in

23667-464: Was also commonly written as the single word Hongkong until 1926, when the government officially adopted the two-word name. Some corporations founded during the early colonial era still keep this name, including Hongkong Land , Hongkong Electric Company , Hongkong and Shanghai Hotels and the Hongkong and Shanghai Banking Corporation (HSBC). Earliest known human traces in what is now Hong Kong are dated by some to 35,000 and 39,000 years ago during

23828-563: Was applied to such varied phenomena as the Challenger Society for Marine Science , the oceanographic and marine geological survey ship Glomar Challenger , and the Space Shuttle Challenger . General Primary reports, accounts, and letters Secondary literature Collections and archives Oceanography Oceanography (from Ancient Greek ὠκεανός ( ōkeanós )  ' ocean ' and γραφή ( graphḗ )  ' writing '), also known as oceanology , sea science , ocean science , and marine science ,

23989-575: Was built in 1882. In 1893, Fridtjof Nansen allowed his ship, Fram , to be frozen in the Arctic ice. This enabled him to obtain oceanographic, meteorological and astronomical data at a stationary spot over an extended period. In 1881 the geographer John Francon Williams published a seminal book, Geography of the Oceans .
