104-690: South Georgia is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands . It lies around 1,400 kilometres (870 mi) east of the Falkland Islands . Stretching in the east–west direction, South Georgia is around 170 kilometres (106 mi) long and has a maximum width of 35 kilometres (22 mi). The terrain

208-492: A World Heritage Site for their geological value, four of them are considered of "Outstanding Universal Value" based on their cultural and natural criteria: Þingvellir , Iceland; Landscape of the Pico Island Vineyard Culture , Portugal; Gough and Inaccessible Islands , United Kingdom; and Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves, Brazil. Continental shelves in

312-459: A British possession, naming it "Isle of Georgia" after King George III . Through its history , it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken . The main settlement and the capital today is King Edward Point near Grytviken, a British Antarctic Survey research station, with a population of about 20 people. The island of South Georgia

416-506: A Navy Sonic Depth Finder to draw a continuous map across the bed of the Atlantic. This involved little guesswork because the idea of sonar is straightforward with pulses being sent from the vessel, which bounce off the ocean floor, then return to the vessel. The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains , trenches , seamounts , basins , plateaus , canyons , and some guyots . Various shelves along

520-451: A San Lorenzo se dirigió inmortal. Aquí está, como el cielo refulgente, ostentando sublime majestad, después de haber cruzado el Continente, exclamando a su paso: ¡Libertad! ¡Libertad! ¡Libertad! Here is the idolized flag, the flag that Belgrano left to us, when the sad enslaved Homeland bravely broke its bonds. Here is the splendorous flag that surprised the world with its victory, when arrogant and victoriously during

624-721: A branch of the Gulf Stream which flows northward from the Grand Banks ; and the Subpolar Front , an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transports warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of

728-669: A national holiday. The date was decided as the anniversary of Belgrano's death in 1820. In 1957 the National Flag Memorial (a 10,000 m monumental complex) was inaugurated in Rosario to commemorate the creation of the flag, and the official Flag Day ceremonies have customarily been conducted in its vicinity since then. In 1978 it was specified, among other measurements, that the Official Ceremony Flag should be 1.4 meters wide and 0.9 meters high, and that

832-473: A pest, damaging the island's flora and wider ecosystem. Karl Erik Kilander, the project manager, said the culled reindeer were frozen and taken to the Falkland Islands where they were sold to local residents and cruise ship operators. In 2018, after a multiyear extermination effort, the island was declared free of invasive rodents and the number of South Georgia pipits had clearly increased. In

936-427: A stepped sequence of flat surfaces interpreted as wave-cut platforms formed when sea level was higher relative to the island. At sea level strandflats have been described. In 2013, teams of Norwegian government shooters and Sámi reindeer herders culled all 3,500 reindeer on the island. The animals had been introduced by Norwegian whalers in the early 20th century for food and sport hunting, but were later seen as

1040-416: A weak Intertropical Convergence Zone , South Atlantic tropical cyclones are rare. The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. The continental margins and continental shelf mark lower density, but greater thickness felsic continental rock that is often much older than that of

1144-635: Is 30 centimeters high. In the center stripe there is an emblem known as the Sun of May ( Spanish : Sol de Mayo ), a golden sun. Historian Diego Abad de Santillán claimed that the Sun of May was a representation of the Inca sun god Inti . Flags with proportions of 1:2 and 2:3 are also in use. The colors are officially defined using the CIE 1976 standard: The following are given for computer, textile, print and plastic use: The Spanish word celeste ( sky blue )

1248-621: Is a complex of four water masses, two that form by deep convection in the open ocean – classical and upper Labrador sea water – and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill – Denmark Strait and Iceland-Scotland overflow water. Along its path across Earth the composition of the NADW is affected by other water masses, especially Antarctic bottom water and Mediterranean overflow water. The NADW

1352-422: Is buried in the cemetery at Grytviken alongside Frank Wild . Commercial sealing was conducted on the island between 1786 and 1913. During that period 131 sealing visits are recorded, eight of which ended when the vessel was wrecked. Modern industrial sealing associated with whaling stations was carried out between 1909 and 1964. Sealing era relics include iron try pots , hut ruins, graves and inscriptions, and

1456-467: Is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. Changes in the formation of NADW have been linked to global climate changes in the past. Since human-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in

1560-498: Is found off the eastern coast of Canada. Surface water temperatures, which vary with latitude, current systems, and season and reflect the latitudinal distribution of solar energy, range from below −2 °C (28 °F) to over 30 °C (86 °F). Maximum temperatures occur north of the equator, and minimum values are found in the polar regions. In the middle latitudes, the area of maximum temperature variations, values may vary by 7–8 °C (13–14 °F). From October to June

1664-575: Is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs fracture zone at 53°N . The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. The MAR rises 2–3 km (1.2–1.9 mi) above the surrounding ocean floor and its rift valley is the divergent boundary between

1768-854: Is intersected by two perpendicular ridges: the Azores–Gibraltar Transform Fault , the boundary between the Nubian and Eurasian plates , intersects the MAR at the Azores triple junction , on either side of the Azores microplate, near the 40°N . A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty fracture zone , approximately at 16°N . In

1872-560: Is mountainous, with the central ridge rising to 2,935 metres (9,629 ft) at Mount Paget . The northern coast is indented with numerous bays and fjords, serving as good harbours . Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in HMS ; Resolution made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it

1976-729: Is now northern and central Brazil. The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. The formation of the isthmus resulted in the migration and extinction of many land-living animals, known as the Great American Interchange , but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents, salinity, and temperatures in both

2080-794: Is now the Carpathian region, that were similar to the Sargasso Sea. It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in

2184-528: Is one of the five flags that use the ratio 5:8, the others being Guatemala , Palau , Poland , and Sweden . The flag of Argentina was created by Manuel Belgrano during the Argentine War of Independence. While in Rosario he noticed that both the royalist and patriotic forces were using the same colors, Spain 's yellow and red. After realizing this, Belgrano created the Cockade of Argentina , which

2288-495: Is used to describe the colour of the blue stripes. The sun is called the Sun of May because it is a replica of an engraving on the first Argentine coin , approved in 1813, whose value was eight escudos (one Spanish dollar). It has 16 straight and 16 waved sunbeams. In 1978 the sun color was specified to be golden yellow ( amarillo oro ), to have an inner diameter of 10 cm, and an outer diameter of 25 cm (the diameter of

2392-985: The Iliad and the Odyssey , this all-encompassing ocean was instead known as Oceanus , the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the West African coast. The term " Aethiopian Ocean ", derived from Ancient Ethiopia ,

2496-797: The Age of Discovery , it was known for separating the New World of the Americas ( North America and South America ) from the Old World of Afro-Eurasia ( Africa , Asia , and Europe ). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were

2600-582: The Argentine flag on the island. On 3 April, the second day of the Falklands War , Argentine naval forces occupied the island. South Georgia was retaken by British forces on 25 April during Operation Paraquet . The island's climate is classified as an ET or polar tundra climate on the Köppen-Geiger classification system . It has no tree cover, and there is generally snow on the island during

2704-564: The Carpathian Basin from where it migrated over Sicily to the central Atlantic where it evolved into modern species of the Sargasso Sea. The location of the spawning ground for European eels remained unknown for decades . In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than 5,000 km (3,100 mi) and

2808-610: The Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like the United States and Brazil , both increased in degree during the early 20th century, and while no major military conflicts have taken place in the Atlantic recently, the ocean remains a core component of trade around the world. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to

2912-530: The Equator . The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): Atlantikôi pelágei (Ancient Greek: Ἀτλαντικῷ πελάγει , ' the Atlantic sea ' , etym . ' Sea of Atlas ' ) and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Ancient Greek: Ἀτλαντὶς θάλασσα , ' Sea of Atlas ' or '

3016-474: The Icelandic Low produces frequent storms. Icebergs are common from early February to the end of July across the shipping lanes near the Grand Banks of Newfoundland . The ice season is longer in the polar regions, but there is little shipping in those areas. Hurricanes are a hazard in the western parts of the North Atlantic during the summer and autumn. Due to a consistently strong wind shear and

3120-684: The North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. The MAR produces basaltic volcanoes in Eyjafjallajökull , Iceland, and pillow lava on the ocean floor. The depth of water at the apex of the ridge is less than 2,700 m (1,500 fathoms ; 8,900  ft ) in most places, while the bottom of the ridge is three times as deep. The MAR

3224-616: The North Atlantic Drift is thought to have at least some influence on climate. For example, the Gulf Stream helps moderate winter temperatures along the coastline of southeastern North America, keeping it warmer in winter along the coast than inland areas. The Gulf Stream also keeps extreme temperatures from occurring on the Florida Peninsula. In the higher latitudes, the North Atlantic Drift, warms

3328-514: The North Atlantic oscillation , occurs. On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general,

3432-690: The Paraná River . On that day, Belgrano said the following words: Soldiers of the Fatherland, we have heretofore had the glory of wearing the national cockade ; there (pointing to the Independence battery), on the Independence Battery, where our Government has recently had the honor of bestowing it upon, shall our weapons enlarge their glory. Let us swear to defeat our enemies, internal and external, and South America will become

3536-555: The Scotia Sea , and other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures 111,866 km (69,510 mi) compared to 135,663 km (84,297 mi) for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km (41,100,000 sq mi) or 23.5% of the global ocean and has a volume of 310,410,900 km (74,471,500 cu mi) or 23.3% of

3640-550: The South Georgia Museum was established on the island in 1992. The island was surveyed by explorer Duncan Carse . He organised and led the South Georgia Survey of 1951–1957, surveying much of the interior of the island. Mount Carse and Carse Point are named after him. In 1961 he lived as a hermit in a remote part of South Georgia. Carse built a house at Ducloz Head on the southern coast of

3744-638: The meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation , are especially pronounced in Labrador Sea Water , the upper layers of the MOC. The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in

3848-458: The thermocline of the subtropical gyre. The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum ( S. fluitans and natans ) float, an area 4,000 km (2,500 mi) wide and encircled by the Gulf Stream , North Atlantic Drift , and North Equatorial Current . This population of seaweed probably originated from Tertiary ancestors on

3952-580: The " Río Juramento " ("Oath River"). The first battle fought with the approved flag was the Battle of Salta , a decisive patriotic victory that achieved the complete defeat of royalist Pío Tristán . The flag would be finally declared the National Flag by the Congress of Tucumán on July 20, 1816, shortly after the declaration of independence . The proposal was made by the deputy Juan José Paso and

4056-578: The 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: An elevated ridge rising to an average height of about 1,900 fathoms [3,500 m; 11,400 ft] below the surface traverses the basins of the North and South Atlantic in a meridianal direction from Cape Farewell, probably its far south at least as Gough Island, following roughly

4160-618: The 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. These include the Baltic Sea , Black Sea , Caribbean Sea , Davis Strait , Denmark Strait , part of the Drake Passage , Gulf of Mexico , Labrador Sea , Mediterranean Sea , North Sea , Norwegian Sea , almost all of

4264-411: The 1960s and CFCs . The clockwise warm-water North Atlantic Gyre occupies the northern Atlantic, and the counter-clockwise warm-water South Atlantic Gyre appears in the southern Atlantic. In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras ; the North Atlantic Current ,

4368-419: The Atlantic and Pacific. Marine organisms on both sides of the isthmus became isolated and either diverged or went extinct. Flag of Argentina The national flag of the Argentine Republic , often referred to as the Argentine flag ( Spanish : bandera argentina ), is a triband , composed of three equally wide horizontal bands coloured light blue and white . There are multiple interpretations on

4472-407: The Atlantic are wide off Newfoundland, southernmost South America, and northeastern Europe. In the western Atlantic carbonate platforms dominate large areas, for example, the Blake Plateau and Bermuda Rise . The Atlantic is surrounded by passive margins except at a few locations where active margins form deep trenches : the Puerto Rico Trench (8,376 m or 27,480 ft maximum depth) in

4576-468: The Atlantic include the Challenger expedition and the German Meteor expedition ; as of 2001 , Columbia University 's Lamont–Doherty Earth Observatory and the United States Navy Hydrographic Office conduct research on the ocean. The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2,000 m (6,600 ft) along most of its length, but

4680-403: The Atlantic north of the equator. The coldest zones are in high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents influence the climate by transporting warm and cold waters to other regions. The winds that are cooled or warmed when blowing over these currents influence adjacent land areas. The Gulf Stream and its northern extension towards Europe,

4784-455: The Atlantic sea ' ) where the name refers to "the sea beyond the pillars of Heracles " which is said to be part of the sea that surrounds all land. In these uses, the name refers to Atlas , the Titan in Greek mythology , who supported the heavens and who later appeared as a frontispiece in medieval maps and also lent his name to modern atlases . On the other hand, to early Greek sailors and in ancient Greek mythological literature such as

4888-409: The Bahamas, while coarse river outwash sands and silt are common in shallow shelf areas like the Georges Bank . Coarse sand, boulders, and rocks were transported into some areas, such as off the coast of Nova Scotia or the Gulf of Maine during the Pleistocene ice ages. The break-up of Pangaea began in the central Atlantic, between North America and Northwest Africa, where rift basins opened during

4992-404: The European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth , floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish , a predator with algae-like appendages which hovers motionless among the Sargassum . Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what

5096-405: The Late Triassic and Early Jurassic. This period also saw the first stages of the uplift of the Atlas Mountains. The exact timing is controversial with estimates ranging from 200 to 170 Ma. The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea , both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of

5200-468: The North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation . Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from

5304-426: The Second Triumvirate, with a more liberal ideology, who called the Asamblea del Año XIII . Despite being one of its original goals, it did not declare independence, and so did not approve the use of a national flag either; nevertheless, the flag made by Belgrano was authorized to be used as a war flag . The first oath to the newly approved flag was on February 13, 1813, next to the Salado River , which became known as

5408-437: The South Atlantic, and the "Atmospheric Bridge", which evaporates subtropical Atlantic waters and exports it to the Pacific. The Atlantic Ocean consists of four major, upper water masses with distinct temperature and salinity. The Atlantic subarctic upper water in the northernmost North Atlantic is the source for subarctic intermediate water and North Atlantic intermediate water. North Atlantic central water can be divided into

5512-412: The atmosphere over the oceans, keeping the British Isles and northwestern Europe mild and cloudy, and not severely cold in winter, like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's northwestern coast. In general, winds transport moisture and air over land areas. Every winter,

5616-404: The battles the top of the Andes it has climbed. Here is the flag that one day triumphantly rose in the middle of the battle and, full of pride and gallantry, to San Lorenzo it went immortal. Here it is, like the shining sky, showing sublimate majesty after having crossed the continent shouting in its way: "Freedom!" "Freedom! Freedom!" As Flag Day is celebrated on June 20,

5720-454: The central north coast, five years after poisoning the rats, the populations of snowy sheathbills , South Georgia pintails and Wilson's storm petrels had grown. The island lies in the path of large icebergs drifting northward from Antarctica. Iceberg A-38 grounded off the island in 2004, resulting in indirect but severe effects on local wildlife by disturbing life on the seafloor and blocking foraging routes of seals and penguins. In 2020,

5824-405: The cockade, the Triumvirate did not accept the use of the flag: policy at the time was to state that the government was ruling on behalf of King Ferdinand VII of Spain who was captive of Napoleon , whereas the creation of a flag was a clear independentist act. Thus, the triumvirate sent a warning to Belgrano not to fight under the flag, but by the time the reply had arrived, Belgrano had moved to

5928-419: The colors to those of the sky , clouds and the sun ; some anthems to the flag like "Aurora" or "Salute to the flag" state so as well. However, historians usually disregard this idea, and attribute them to loyalty towards the House of Bourbon . After the May Revolution, the first times of the Argentine War of Independence, the Triumvirate claimed to be acting on behalf of the Spanish King Ferdinand VII, who

6032-503: The colossal 4,200-square-kilometre (1,600 sq mi) Iceberg A-68 , similar in size to the island itself, was initially believed to be on a similar collision course but broke apart before collision with the island. Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceanic divisions , with an area of about 85,133,000 km (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area. During

6136-408: The country during the Argentine War of Independence and other wars that followed. The Glorious Reveille may be sounded by a military or a marching band at this point, and confetti may be showered upon the students. In the Armed Forces of the Argentine Republic and civil uniformed services the pledge is similar but with a different formula and response of ¡Si, juro! ( Yes, I pledge! ) In

6240-401: The creation or first uses of the flag show the modern design of it, but the flag of Macha , a very early design kept at the House of Freedom in Sucre , Bolivia was instead a vertical triband with two white bands and a light blue one in the middle. The flag was first flown for soldiers to swear allegiance to it on 27 February 1812, by personnel of the Batería Libertad (Liberty Battery), by

6344-798: The dissolution of the Union, the five countries became independent, but even today all of these states except Costa Rica use flags of blue-white-blue stripes (the Costa Rican flag has a compound red stripe on the white one, added to incorporate all the colors of the French flag ). The Argentine flag also inspired the flag of Uruguay . Alta en el cielo, un águila guerrera Audaz se eleva en vuelo triunfal. Azul un ala del color del cielo, Azul un ala del color del mar. Así en el alta aurora irradial. Punta de flecha el áureo rostro imita. Y forma estela el purpurado cuello. El ala es paño, el águila es bandera.

6448-425: The east, and the Americas to the west. As one component of the interconnected World Ocean , it is connected in the north to the Arctic Ocean , to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south. Other definitions describe the Atlantic as extending southward to Antarctica . The Atlantic Ocean is divided in two parts, the northern and southern Atlantic, by

6552-431: The east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea  – one of its marginal seas  – and, in turn, the Black Sea , both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian , running south from Cape Agulhas to Antarctica defines its border. In

6656-544: The eastern and western North Atlantic central water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean water. North Atlantic central water flows into South Atlantic central water at 15°N . There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic intermediate water flows from

6760-430: The first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus' expedition ushered in an age of exploration and colonization of the Americas by European powers , most notably Portugal , Spain , France , and the United Kingdom . From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and

6864-461: The first landing, survey and mapping of South Georgia. As mandated by the Admiralty , on 17 January 1775 he took possession for Britain and renamed the island 'Isle of Georgia' for King George III . After making a foot crossing of the island with Tom Crean and Frank Worsley , Ernest Shackleton organised the rescue of his party from Elephant Island following the disaster that befell the 1916 Imperial Trans-Antarctic Expedition , which he led. He

6968-406: The flag at San Salvador de Jujuy and had it blessed by the local church on the second anniversary of the May Revolution. Belgrano accepted the orders from the Triumvirate by time they arrived to Salta and ceased using the flag. As soldiers had already made oaths to the new flag, Belgrano said that he was saving it for the circumstance of a great victory. The First Triumvirate was later replaced by

7072-441: The following pledge is recited to students nationwide on this day by their respective school principals or grade level advisers. In large towns where students are gathered en masse, the pledge is taken by the local town or city executive, preceded by words of advice and honor to the memory of its creator, Manuel Belgrano, using the following or similar formulas: Versions of this include references to Belgrano and to all who fought for

He managed to salvage enough gear to survive the winter until making contact with a ship 116 days later. His knowledge and mapping proved helpful to the British during the Falklands conflicts. On 19 March 1982, a group of Argentinians arrived at Leith Harbour and raised

7280-454: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of

7384-474: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To

7488-501: The lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into

7592-514: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss
