Politically, the Marshall Islands is a parliamentary republic with an executive presidency in free association with the United States, with the U.S. providing defense, subsidies, and access to U.S.-based agencies such as the Federal Communications Commission and the United States Postal Service . With few natural resources, the islands' wealth
312-518: A piloting technique of interpreting disruptions in ocean swells to determine the location of low coral atolls below the horizon. They noticed that swells refracted around the undersea slope of atolls. When refracted swells from different directions met, they created noticeable disruption patterns, which Marshallese pilots could read to determine the direction of an island. When interviewed by anthropologists, some Marshallese sailors noted that they piloted their canoes by both sight and feeling changes in
416-821: A stub . You can help Misplaced Pages by expanding it . Island An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics , and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcanic activity, grow into atolls from coral reefs , and form from sediment along shorelines, creating barrier islands . River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. Islands are host to diverse plant and animal life. Oceanic islands have
520-451: A "commuting" distance to an island that has enough resources to be sustainable. The presence of an island is marked by seabirds , differences in cloud and weather patterns, as well as changes in the direction of waves. It is also possible for human populations to have gone extinct on islands, evidenced by explorers finding islands that show evidence of habitation but no life. Not all islands were or are inhabited by maritime cultures. In
624-514: A "rafting event". This phenomenon is known as oceanic dispersal . Tropical storms have the capacity to transport species over great distances. Animals like tortoises can live for weeks without food or water, and are able to survive floating on debris in the sea. One case study showed that in 1995, fifteen iguanas survived a 300 km journey to Anguilla in the Caribbean , an island which no iguana had lived on previously. They survived floating on
728-426: A detailed review of 1,288 islands found that they were home to 1,189 highly-threatened vertebrate species, which was 41 percent of the global figure. Coral bleaching is expected to occur with more frequency, threatening marine ecosystems, some of which island economies are dependent on. Some islands that are low-lying may cease to exist given high enough amounts of sea level rise. Tuvalu received media attention for
832-614: A few meters high, and are usually temporary. Changes in the flow speed, water level, and sediment content of the river may effect the rate of fluvial island formation and depletion. Permanent river islands also exist, the largest of which (that is completely inland) is Bananal Island in the Tocantins of Brazil, which has a maximum width of 55 kilometers. Lakes form for a variety of reasons, including glaciers , plate tectonics, and volcanism. Lake islands can form as part of these processes. The field of insular biogeography studies

He also noted that Marshallese iroij held considerable authority and rights to all property, though he had a more favorable view of the condition of Marshallese commoners than of that of Polynesian commoners. The Marshalls' two island groups, the Ratak and Ralik chains, were each ruled by a paramount chief, or iroijlaplap, who held authority over
1040-402: A higher carrying capacity also have more genetic diversity , which promotes speciation . Oceanic islands, ones that have never been connected to shore, are only populated by life that can cross the sea. This means that any animals present on the island had to have flown there, in the case of birds or bats , were carried by such animals, or were carried in a sea current in what is known as
1144-477: A loss of almost all the infrastructure in Dominica. Sea level rise and other climate changes can reduce freshwater reserves, resulting in droughts . These risks are expected to decrease the habitability of islands, especially small ones. Beyond risks to human life, plant and animal life are threatened. It has been estimated that almost 50 percent of land species threatened by extinction live on islands. In 2017,

New Zealand and Australia share 200 native plant species, despite being separated by 1500 km. Continental islands, islands that were at one point connected to a continent, are expected to share a common history of plant and animal life up until the point that the island broke away from
1352-837: A minimum. Some islands became host to humans due to a land bridge or a continental island splitting from the mainland. Today, up to 10% of the world's population lives on islands. Islands are popular targets for tourism due to their perceived natural beauty, isolation, and unique cultures. Islands became the target of colonization by Europeans, resulting in the majority of islands in the Pacific being put under European control. Decolonization has resulted in some but not all island nations becoming self-governing , with lasting effects related to industrialisation , invasive species , nuclear weapons testing , and tourism . Islands and island countries are threatened by climate change . Sea level rise threatens to submerge nations such as Maldives ,
1456-743: A minority. Cultural attitudes related to communal ownership of land as well as a lack of individualistic decision-making may make some island cultures less compatible with the global capitalist economy, causing these nations to experience less economic growth. Islands have long been a popular target for tourism , thanks to their unique climates, cultures, and natural beauty. However, islands may suffer from poor transportation connectivity from airplanes and boats and strains on infrastructure from tourist activity. Islands in colder climates often rely on seasonal tourists seeking to enjoy nature or local cultures, and may only be one aspect of an island's economy. In contrast, tourism on tropical islands can often make up
1560-465: A mission church and school at Ebon . By 1875, the missionaries had established churches on five atolls and had baptized more than 200 islanders, and one traveler noted that most women on Ebon wore western clothes and many men wore trousers by the mid-1870s. In 1859, Adolph Capelle and another merchant arrived at Ebon and set up a trading post for the German company Hoffschlaeger & Stapenhorst. When

The British government protested the regulations benefiting the Jaluit Company as a violation of the Anglo-German Declarations' free-trade provision. On March 31, 1906, the German government assumed direct control and reorganized the Marshall Islands and Nauru as part of the protectorate of German New Guinea . The Imperial Japanese Navy invaded Enewetak on September 29, 1914, and Jaluit on September 30 at

The majority of the citizens of the Republic of Marshall Islands are of Marshallese descent, though there are small numbers of immigrants from the United States, China, Philippines , and other Pacific islands. The two official languages are Marshallese , which is one of the Oceanic languages , and English . Almost the entire population of
1872-613: A permanent caisson , a steel or concrete structure built in a closed loop and then filled with sand. Some modern islands have been constructed by pouring millions of tons of sand into the sea, such as with Pearl Island in Qatar or the Palm Islands in Dubai. These islands are usually created for real estate development , and are sold for private ownership or construction of housing. Offshore oil platforms have also been described as
1976-524: A phenomenon where new oceanic crust is formed, pushing away older crust. Islands sitting on the continental shelf may be called continental islands. Other islands, like those that make up New Zealand , are what remains of continents that shrank and sunk beneath the sea. It was estimated that Zealandia , the continent-like area of crust that New Zealand sits on, has had 93% of its original surface area submerged. Some islands are formed when coral reefs grow on volcanic islands that have submerged beneath
2080-423: A press conference publicizing the ongoing submerging of the island country. Tuvalu signed a cooperation agreement with Australia agreeing to annually allow 280 of its citizens to become permanent residents of Australia. The Marshall Islands, a country of 1,156 islands, have also been identified as a country that may be existentially threatened by rising seas. Increasing intensity of tropical storms also increases
2184-483: A priority target of conservation efforts, to prevent the extinction of these species. Despite high levels of endemism, the total species richness , the total number of unique species in a region, is lower on islands than on mainlands. The level of species richness on islands is proportional to the area of that island, a phenomenon known as the species-area relationship . This is because larger areas have more resources and thus can support more organisms. Populations with

Trusteeship was ended under United Nations Security Council Resolution 683 of December 22, 1990. Until 1999 the islanders received US$ 180 million for continued American use of Kwajalein atoll, US$ 250 million in compensation for nuclear testing , and US$ 600 million in other payments under
2496-529: A relatively dry season from December to April and a wet season from May to November. Many Pacific typhoons begin as tropical storms in the Marshall Islands region and grow stronger as they move west toward the Mariana Islands and the Philippines . Population has outstripped the supply of fresh water, usually from rainfall. The northern atolls get 50 inches (1,300 mm) of rainfall annually;
2600-411: A restricted set of natural resources. However, these nations control some of the largest fisheries in the world, deposits of copper , gold , and nickel , as well as oil deposits . The natural beauty of island nations also makes them a magnet for tourism . Islands also have geopolitical value for naval bases , weapons testing , and general territorial control. One such example is French Polynesia ,
2704-476: A selection pressure for smaller animals that require less food. Having fewer predators would mean these animals did not need not be large to survive. Charles Darwin formulated the theory of natural selection through the study of island ecology. The species he observed on the Galápagos Islands , including tanager birds, contributed to his understanding of how evolution works. He first traveled to
2808-509: A specific property known as adaptive radiation . In this process, a species that arrives on a group of islands rapidly becomes more diverse over time, splitting off into new species or subspecies. A species that reaches an island ecosystem may face little competition for resources, or may find that the resources that they found in their previous habitat are not available. These factors together result in individual evolutionary branches with different means of survival. The classical example of this
2912-414: A territory that receives substantial military expenditure and aid from France. Since the first discoveries of Polynesian, Micronesian , and other islands by Westerners, these nations have been the subject of colonization. Islands were the target of Christian missionaries . These missionaries faced resistance, but found success when some local chiefs used European support to centralize power. Beginning in
3016-497: A total of 29 atolls and five individual islands situated in about 180,000 square miles (470,000 km ) of the Pacific. The largest atoll with a land area of 6 square miles (16 km ) is Kwajalein. It surrounds a 655-square-mile (1,700 km ) lagoon. Twenty-four of the atolls and islands are inhabited. The remaining atolls are uninhabited due to poor living conditions, lack of rain, or nuclear contamination. The uninhabited atolls are: The average altitude above sea level for
3120-519: A tree that is present in Australia, New Zealand, parts of South American, and New Guinea, places that today are geographically distant. A possible explanation for this phenomenon is that these landmasses were once all part of the continent Gondwana and separated by tectonic drift. However, there are competing theories that suggest this species may have reached faraway places by way of oceanic dispersal. Species that colonize island archipelagos exhibit

The Marshall Islands also lays claim to Wake Island based on oral legends. While Wake Island has been administered by the United States since 1899, the Marshallese government refers to it by the name Ānen Kio (new orthography) or Enen-kio (old orthography). The United States does not recognize this claim. The climate has

These species compete for resources with native animals, and some may grow so densely that they displace other forms of existing life. For hundreds of years, islands have been created through land reclamation . One of the first recorded instances of this when people of

Larger animals such as the hippopotamus tend to become smaller, such as in the case of the pygmy hippopotamus . This is known as insular dwarfism . In the case of smaller animals, it has been hypothesized that animals on islands may have fewer predators and competitors, resulting in selection pressure towards larger animals. Larger animals may exhaust food resources quickly due to their size, causing malnutrition in their young, resulting in

4368-784: The Gilbert Islands and Marshall Islands. On June 25, 1788, the British ships had peaceful interactions and traded with islanders at Mili Atoll ; their meeting may have been the first contact between Europeans and Marshallese since the Mendaña expedition of 1568. Subsequent navigational charts and maps named the islands for John Marshall. From the 1820s through the 1850s, the Marshall Islanders became increasingly hostile to western vessels, possibly because of violent punishments that sea captains exacted for theft as well as

Species that live exclusively on islands are some of those most threatened by extinction . An island is an area of land surrounded by water on all sides that is distinct from a continent. There is no standard of size that distinguishes islands and continents . Continents have an accepted geological definition – they are
4576-507: The Polynesians . Many of the previous island settlements required traveling distances of less than 100 km (62 mi), whereas Polynesians may have traveled 2,000–3,200 km (1,200–2,000 mi) to settle islands such as Tahiti . They would send navigators to sail the ocean without the aid of navigational instruments to discover new islands for settlement. Between 1100 and 800 BC, Polynesians sailed East from New Guinea and
4680-891: The Solomon Islands and reached the islands that make up the modern-day Fiji and Samoa . The furthest extent of this migration would be Easter Island in the East, and New Zealand in the South, with New Zealand's first settlements between 1250 and 1300. Historians have sought to understand why some remote islands have always been uninhabited, while others, especially in the Pacific Ocean , have long been populated by humans. Generally, larger islands are more likely to be able to sustain humans and thus are more likely to have been settled. Small islands that cannot sustain populations on their own can still be habitable if they are within
4784-499: The Solomon Islands created eighty such islands by piling coral and rock in the Lau Lagoon . One traditional way of constructing islands is with the use of a revetment . Sandbags or stones are dropped with a barge into the sea to bring the land level slightly out of the water. The island area is then filled with sand or gravel, followed by a construction of this revetment to hold it together. Islands have also been constructed with
4888-616: The abduction of Marshallese people for sale into slavery on Pacific plantations. One of the earliest violent encounters occurred in February 1824, when the inhabitants of Mili Atoll massacred marooned sailors from the American whaler Globe . Similar encounters occurred as late as 1851 and 1852, when three separate Marshallese attacks on ships occurred at Ebon , Jaluit , and Namdrik Atolls . In 1857, American Board of Commissioners for Foreign Missions sent two families to establish

For some islands, the movement of tectonic plates above stationary hotspots would form islands in a linear chain, with the islands further away from the hotspot being progressively older and more eroded , before disappearing under
5096-450: The sea as a natural barrier to the introduction of new species, causing the species that do reach the island to evolve in isolation. Continental islands share animal and plant life with the continent they split from. Depending on how long ago the continental island formed, the life on that island may have diverged greatly from the mainland due to natural selection . Humans have lived on and traveled between islands for thousands of years at

The British sea captains John Marshall and Thomas Gilbert visited the islands in 1788. Their vessels had been part of the First Fleet taking convicts from England to Botany Bay in New South Wales , and were en route to Guangzhou when they passed through
5512-819: The British and German governments conducted a series of secret negotiations to divide the Western Pacific into spheres of influence . The German sphere included the Marshall Islands. On November 26, 1878, the German warship SMS Ariadne anchored at Jaluit to begin treaty negotiations with the chiefs to grant the German Empire " most favored nation " status in the Ralik Chain. During the second day of negotiations, Captain Bartholomäus von Werner [ de ] ordered his men to give military demonstrations which he later said were intended to "show

On March 27, 1933, Japan declared its intentions to withdraw from the League of Nations , officially withdrawing in 1935 but continuing to control the territory of the South Seas Mandate. Japanese military planners initially discounted the Marshalls as too distant and indefensible for extensive fortification, but as Japan developed long-range bombers,

6344-682: The Origin of Species . The first evidence of humans colonizing islands probably occurred in the Paleolithic era, 100,000 to 200,000 years ago. Reaching the Indonesian islands of Flores and Timor would have required crossing distances of water of at least 29 km (18 mi). Some islands, such as Honshu , were probably connected to the mainland with a land bridge that allowed humans to colonize it before it became an island.

Nuclear weapons testing on the Marshall Islands left many atolls destroyed or uninhabitable, causing the forced displacement of people from their home islands as well as increases in cancer rates due to radiation . Colonization has resulted in a decline of observance of traditional cultural practices in places such as Hawaii, where Native Hawaiians are now

By 1885, the German firms Hernsheim & Co . and Deutsche Handels- und Plantagen-Gesellschaft Der Südsee Inseln zu Hamburg controlled two-thirds of the trade. Contact between the Marshallese and westerners led to sometimes lethal outbreaks of western diseases, including influenza , measles , syphilis , and typhoid fever . Increased access to alcohol led to social problems in some Marshallese communities, and on several atolls conflicts erupted between rival iroij with access to firearms. In 1875,

It was not until 1999, following political corruption allegations, that the aristocratic government was overthrown, with Imata Kabua replaced by the commoner Kessai Note . The Runit Dome was built on Runit Island to deposit U.S.-produced radioactive soil and debris, including lethal amounts of plutonium . There are ongoing concerns about deterioration of
7280-406: The continent. For example, the presence of freshwater fish on an island surrounded by ocean would indicate that it once was attached to a continent, since these fish cannot traverse the ocean on their own. Over the course of time, evolution and extinction changes the nature of animal life on a continental island, but only once it splits from the mainland. An example is that of the southern beech ,
7384-451: The deposition of sediment by waves . These islands erode and grow as the wind and waves shift. Barrier islands have the effect of protecting coastal areas from severe weather because they absorb some of the energy of large waves before they can reach the shore. A fluvial island is an island that forms from the erosion and sedimentation of debris in rivers; almost all rivers have some form of fluvial islands. These islands may only be

Scientists often study islands as an isolated model of how the process of natural selection takes place. Island ecology studies organisms on islands and their environment. It has yielded important insights for its parent field of ecology since
7800-457: The entire country is 7 feet (2.1 m). In October 2011, the government declared that an area covering nearly 2,000,000 square kilometers (772,000 sq mi) of ocean shall be reserved as a shark sanctuary . This is the world's largest shark sanctuary, extending the worldwide ocean area in which sharks are protected from 2,700,000 to 4,600,000 square kilometers (1,042,000 to 1,776,000 sq mi). In protected waters, all shark fishing
7904-439: The entire world. Austronesian settlers reached the Marshall Islands as early as the 2nd millennium BC and introduced Southeast Asian crops, including coconuts , giant swamp taro , and breadfruit , as well as domesticated chickens, which made the islands permanently habitable. Several Spanish expeditions visited the islands in the mid-16th century, but Spanish galleons usually sailed a Pacific route farther north and avoided
8008-503: The evolving political status of the Marshall Islands, the United States recognized the constitution of the Marshall Islands and the establishment of the Government of the Republic of the Marshall Islands. The constitution incorporates both American and British constitutional concepts. There have been a number of local and national elections since the Republic of the Marshall Islands was founded. The United Democratic Party, running on
8112-790: The expedition of Álvaro de Saavedra Cerón landed on an uninhabited island, possibly in Ailinginae Atoll , where they resupplied and stayed for six days. Natives from a neighboring island briefly met the Spanish. This expedition named the islands 'Los Pintados' or "the Painted Ones" for the natives who wore tattoos. Later Spanish explorers of the Marshalls included Ruy López de Villalobos , Miguel López de Legazpi , Alonso de Arellano , and Álvaro de Mendaña de Neira , though coordinates and geographic descriptions in 16th century Spanish logs are sometimes imprecise, leaving uncertainty about
8216-412: The firm went bankrupt in 1863, Capelle partnered with Portuguese ex-whaler Anton Jose DeBrum to establish a copra trading firm: Capelle & Co. In 1873, the company moved its headquarters to Jaluit , the home of Kabua , a powerful iroij and disputed successor for the paramount chieftainship of the southern Ralik Chain . In the 1870s, various other companies from Germany, Hawaii, New Zealand, and
8320-523: The first American air raids on Japanese territory. The United States invaded the Marshall Islands on January 31, 1944, during the Gilbert and Marshall Islands campaign . The Americans simultaneously invaded Majuro and Kwajalein. By autumn 1944, the Americans controlled all of the Marshall Islands, except for Jaluit, Maloelap, Mili, and Wotje. As the American campaign advanced through Micronesia and into
8424-449: The habit of true warbler species) consumes spiders and insects that live on plants. Other examples of this phenomenon exist worldwide, including in Hawaii and Madagascar, and are not limited to island ecosystems. Species endemic to islands show a common evolutionary trajectory. Foster's rule (also known as the island rule), states that small mammals such as rodents evolve to become larger, known as island gigantism . One such example
8528-489: The individual island iroij. On August 21, 1526, Spanish explorer Alonso de Salazar was the first European to sight the Marshall Islands. While commanding the Santa Maria de la Victoria , he sighted an atoll with a green lagoon, which may have been Taongi . The crew could not land, because of strong currents and water too deep for the ship's anchor, so the ship sailed for Guam two days later. On January 2, 1528,
8632-476: The island is Mt. Kinzō . Economic activity on the island consists of fishing and cultivation of vegetables and citrus fruit. Hashirajima is connected to the port at Iwakuni Mondays through Saturdays by a high speed ferry. The island is best known for its association in World War II with the surrounding Hashirajima Anchoring Area , located 30 to 40 kilometres (16 to 22 nmi; 19 to 25 mi) south of
8736-662: The islanders, who have not seen anything like it before, the power of the Europeans." On November 29, Werner signed a treaty with Kabua and several other Ralik Chain iroij which secured a German fuelling station at Jaluit and free use of the atoll's harbor. On August 29, 1885, German Chancellor Otto von Bismarck authorized the annexation of the Marshall Islands as a protectorate following repeated petitions by German business interests. The German gunboat Nautilus docked at Jaluit on October 13 to take control. On October 15, iroij Kabua, Loeak, Nelu, Lagajime, and Launa signed
8840-457: The islands as a naturalist on HMS Beagle in 1835, as part of a five-year circumnavigation of Earth. He wrote that "the different islands to a considerable extent are inhabited by a different set of beings". Through the study of the finches and other animals he realized that organisms survive by changing to adapt to their habitat. It would be over twenty years before he published his theories in On
8944-650: The islands became useful as a forward base to attack Australia, British colonies, and the United States. In 1939 and 1940, the navy built military airfields on Kwajalein , Maloelap , and Wotje Atolls as well as seaplane facilities at Jaluit. After the outbreak of the Pacific War , the United States Pacific Fleet carried out the Marshalls–Gilberts raids , which struck Jaluit, Kwajalein, Maloelap, and Wotje on February 1, 1942. They were
9048-511: The islands from late 1914 through 1921. The civilian South Seas Government ( 南洋廳 , Nan'yō-chō ) set up its headquarters in Palau in April 1922 and administered the Marshalls until World War II. Japanese surveys determined that the Marshalls' value was primarily strategic, because they could enable future southward expansion . The Marshalls also continued to be a major producer of copra during
9152-789: The islands practices some religion: three-quarters of the country follows either the United Church of Christ – Congregational in the Marshall Islands (UCCCMI) or the Assemblies of God . Linguistic and anthropological studies have suggested that the first Austronesian settlers of the Marshall Islands arrived from the Solomon Islands . Radiocarbon dating suggests that Bikini Atoll may have been inhabited as early as 1200 BCE, though samples may not have been collected from secure stratigraphic contexts and older driftwood samples may have affected results. Archaeological digs on other atolls have found evidence of human habitation dating around
9256-643: The largest landmass of a particular tectonic plate . Islands can occur in any body of water, including lakes , rivers , seas . Low-tide elevations , areas of land that are not above the surface during a high tide , are generally not considered islands. Islands that have been bridged or otherwise joined to a mainland with land reclamation are sometimes considered "de-islanded", but not in every case. The word island derives from Middle English iland , from Old English igland (from ig or ieg , similarly meaning 'island' when used independently, and -land carrying its contemporary meaning. Old English ieg
9360-404: The mainland, they had no need for boats. The motivation for island exploration has been the subject of research and debate. Some early historians previously argued that early island colonization was unintentional, perhaps by a raft being swept out to sea. Others compare the motivations of Polynesian and similar explorers with those of Christopher Columbus , the explorer who sailed westward over
9464-589: The majority of the local economy and built environment . These islands sometimes also require consistent foreign aid on top of tourism in order to ensure economic growth. This reliance can result in social inequality and environmental degradation . During tourism downturns, these economies struggle to make up the lost inflow of cash with other industries. Climate change threatens human development on islands due to sea level rise , more dangerous tropical cyclones , coral bleaching , and an increase in invasive species . For example, in 2017 Hurricane Maria caused
9568-454: The motion of the boat. Sailors also invented stick charts to map the swell patterns, but unlike western navigational charts, the Marshallese stick charts were tools for teaching students and for consultation before embarking on a voyage; navigators did not take charts with them when they set sail. When Russian explorer Otto von Kotzebue visited the Marshalls in 1817, the islanders still showed few signs of western influence. He observed that
9672-547: The naval base at Kure, Hiroshima . Warships of the Imperial Japanese Navy that did not need dock repairs would anchor at Hashirajima, and it was also used as a staging area before fleet departures. It was also the site of the loss of the Japanese battleship Mutsu , which suffered an internal explosion and sank there on 8 June 1943. This article about a location in Yamaguchi Prefecture is
9776-434: The north, so communities in the wet south subsisted on prevalent taro and breadfruit, while northerners were more likely to subsist on pandanus and coconuts. Southern atolls probably supported larger, more dense populations. The Marshallese sailed between islands on walaps made from breadfruit-tree wood and coconut-fiber rope. They navigated by using the stars for orientation and initial course setting, but also developed
9880-529: The past, some societies were found to have lost their seafaring ability over time, such as the case of the Canary Islands , which were occupied by an indigenous people since the island's first discovery in the first century until being conquered by the Spanish Empire in 1496. It has been hypothesized that since the inhabitants had little incentive for trade and had little to any contact with
9984-534: The region. Over the years just one of over 60 islands was cleaned by the U.S. government, and the inhabitants are still waiting for the 2 billion dollars in compensation assessed by the Nuclear Claims Tribunal. Many of the islanders and their descendants still live in exile, as the islands remain contaminated with high levels of radiation. A significant radar installation was constructed on Kwajalein atoll. On May 1, 1979, in recognition of
10088-775: The same legal rights. Marshall Islands The Marshall Islands ( Marshallese : Ṃajeḷ ), officially the Republic of the Marshall Islands ( Marshallese : Aolepān Aorōkin Ṃajeḷ ), is an island country west of the International Date Line and north of the equator in the Micronesia region of the Northwestern Pacific Ocean . The territory consists of 29 coral atolls and five main islands as well as 1,220 other very small ones, divided across two island chains : Ratak in
10192-789: The sea entirely. An example is the Hawaiian Islands , with the oldest island being 25 million years old, and the youngest, Hawaii , still being an active volcano . However, not all island chains are formed this way. Some may be formed all at once by fractures in the tectonic plates themselves, simultaneously creating multiple islands. One supporting piece of evidence is that of the Line Islands , which are all estimated to be 8 million years old, rather than being different ages. Other island chains form due to being separated from existing continents. The Japanese archipelago may have been separated from Eurasia due to seafloor spreading ,
10296-415: The specific islands they sighted and visited. On July 6, 1565, the Spanish ship San Jeronimo nearly wrecked at Ujelang Atoll after the ship's pilot Lope Martín led a mutiny. While the mutineers were resupplying at Ujelang, several crew members took back control of the ship and marooned Martín and twenty-six other mutineers in the Marshalls. By the late 16th century, Spanish galleons sailing between
10400-549: The study of islands is due to their unique cultures and natural environments that differ from mainland cultures. This is for a few reasons: First, the obvious political and geographic isolation from mainland cultures. Second, unique restraints on resources and ecology creating marine-focused cultures with a focus on fishing and sailing. Third, a lasting historical and political significance of islands. The Polynesian diet got most of its protein from fishing. Polynesians were known to fish close to shore, as well as in deep water. It
10504-450: The surface. When these coral islands encircle a central lagoon , the island is known as an atoll . The formation of reefs and islands related to those reefs is aided by the buildup of sediment in shallow patches of water. In some cases, tectonic movements lifting a reef out of the water by as little as 1 meter can cause sediment to accumulate and an island to form. Barrier islands are long, sandy bars that form along shorelines due to
10608-438: The time of Charles Darwin . In biology, endemism is defined as the phenomenon where species or genus is only found in a certain geographical area. Islands isolate land organisms from others with water, and isolate aquatic organisms living on them with land. Island ecosystems have the highest rates of endemism globally. This means that islands contribute heavily to global biodiversity . Areas with high lives of biodiversity are
10712-403: The waste site and a potential radioactive spill . In February 2018, the Marshall Islands became the first country in the world to recognize its cryptocurrency as its own legal tender for digital currency . In January 2020, David Kabua , son of founding president Amata Kabua , was elected as the new President of the Marshall Islands . His predecessor Hilda Heine lost the position after
10816-470: Was reported that Rapa Nui people were known to fish as far as 500 km (310 mi) from shore at coral reefs. Spear , line , and net fishing were all used, to catch tuna as well as sharks and stingrays . Island cultures also cultivate native and non-native crops. Polynesians grew the native yam , taro , breadfruit , banana , coconut and other fruits and vegetables. Different island climates made different resources more important, such as
