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
1725-463: 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
1840-498: 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

Located on the shore of Table Bay , the City Bowl area of Cape Town is the oldest urban area in
2300-693: 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
2415-762: 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

It is used mostly when referring to events or circumstances "on this side of the pond" or "on the other side of the pond" or "across
2990-533: The Anglo-Dutch Treaty of 1814 . The city became the capital of the newly formed Cape Colony , whose territory expanded very substantially through the 1800s, partially as a result of numerous wars with the amaXhosa on the colony's eastern frontier. In 1833 slavery was abolished in the colony freeing over 5500 slaves in the city, almost a third of the city's population at the time. The Convict Crisis of 1849, marked by substantial civil upheaval, bolstered
3105-695: The Cape Supergroup , of which parts of the Graafwater and Peninsula Formations remain, were uplifted between 280 and 21S million years ago, and were largely eroded away during the Mesozoic. The region was geologically stable during the Tertiary, which has led to slow denudation of the durable sandstones. Erosion rate and drainage has been influenced by fault lines and fractures, leaving remnant steep-sided massifs like Table Mountain surrounded by flatter slopes of deposits of

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
8855-544: 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
8970-719: 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 , was applied to the southern Atlantic as late as the mid-19th century. During
9085-607: The entire bottom of False Bay exposed. During this period an extensive system of dunes was formed on the sandy floor of False Bay. At this time the drainage outlets lay between Rocky Bank Cape Point to the west, and between Rocky Bank and Hangklip Ridge to the east, with the watershed roughly along the line of the contact zone east of Seal Island and Whittle Rock. Cape Town has a warm summer Mediterranean climate ( Köppen : Csb ), with mild, moderately wet winters and dry, warm summers. Winter, which lasts from June to September, may see large cold fronts entering for limited periods from

The Gorinaiqua were one of
9430-510: 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
9545-607: The legislative capital of the Union, and later of the Republic of South Africa . By the time of the 1936 census , Johannesburg had overtaken Cape Town as the largest city in the country. In 1945 the expansion of the Cape Town foreshore was completed adding an additional 194 ha (480 acres) to the City Bowl area to the city centre. Prior to the mid-twentieth century, Cape Town was one of

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
9775-492: 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

The legacy of apartheid's spatial planning is still evident, with significant disparities between affluent areas and impoverished townships . 60% of the city's population live in townships and informal settlements far from
10350-803: The most racially integrated cities in South Africa. In the 1948 national elections , the National Party won on a platform of apartheid (racial segregation) under the slogan of " swart gevaar " (Afrikaans for "black danger"). This led to the erosion and eventual abolition of the Cape's multiracial franchise . In 1950, the apartheid government first introduced the Group Areas Act , which classified and segregated urban areas according to race. Formerly multi-racial suburbs of Cape Town were either purged of residents deemed unlawful by apartheid legislation, or demolished. The most infamous example of this in Cape Town
