Deepest Lakes in the World
Lake Malawi, known as Nyasa is third in Africa and the ninth largest lake in the world. It is located between Malawi, Mozambique and Tanzania, at a height of 472 meters in the deep fault depression.
There are underwater volcanoes. The lake is extremely rich in species – fish, birds, crocodiles, hippos, very rare worldwide.
Lake Malawi is sometimes called ‘Calendar Lake’ because it is 365 miles long and 52 miles wide.
It was discovered in 1616 by Portuguese Gaspari Bokaru.
It has a surface area of 1,013 square kilometers, an elevation of 250 meters above mean sea level, and a shoreline length of 525 kilometers. Viewed from above, the lake consists of a series of finger-shaped flooded valleys, of which 554 square kilometers are in Chile and 459 square kilometers in Argentina, although sources differ on the precise split, presumably reflecting water level variability.
The lake is the deepest in the Americas with a maximum depth of 836 meters near O’Higgins Glacier, and its characteristic milky light-blue color comes from rock flour suspended in its waters. It is mainly fed by the Mayer River and other streams, and its outlet, the Pascua River, discharges water from the lake towards the Pacific Ocean at a rate of 510 cubic meters/s.
The O’Higgins Glacier flows eastwards towards the lake, as does the Chico Glacier. Both of these glaciers are part of the Southern Patagonian Ice Field which extends for approximately 350 kilometers in a north-south direction to the west of Lake O’Higgins.
Lake Vostok is the largest of the nearly 400 known as glacial lakes in Antarctica. The lake is located on the South Pole in the Russian polar base “Vostok” which is 3488 m above sea level. The surface of this freshwater lake is about 4000 m below the surface of the ice, which is about 500 m below sea level.
Its length is 250 km, in its widest part is 50 km, covering an area of 15 690 square km, and its average depth is 344 m. The lake is divided into two deep pools of the ridge. Liquid water over the ridge is about 200 m.
The existence of under glacier lake in the polar station “Vostok” was suggested by the Russian geographer Andrei Kapitsa, based on seismic drilling made during the Soviet Antarctic expeditions in 1959 and 1964 to measure the thickness of ice. Continuing research by Russian and British scientists confirmed the existence of the lake.
Caspian Sea is the largest non-draining pool on Earth. Salinity fluctuates from 11-13 ‰, in the northwest to 0.05 ‰. It is situated at an altitude of -28 meters (below sea level), its level in different centuries. Its total area is 371,000 square km. In the northern part the depth reaches 22 meters, and in the south to 1025 meters.
Caspian Sea is situated between the continents of Europe and Asia and is bordered by five countries: Russia, Kazakhstan, Turkmenistan, Iran, Azerbaijan. In Lake flow into these rivers Volga, Ural, Terek, Kura and others. Major ports are Astrakhan, Makhachkala, Baku, Lenkoran, Aktau.
In shelf were discovered large deposits of oil and natural gas. It develops production of caviar and fish (especially sturgeon).
Tanganyika is a large lake in Central Africa, discovered by Europeans in 1858. Its name comes from the former country and colony of the same name that existed independently of the east of it until 1964, in what is now Tanzania. The length of the lake is about 650 km, and its width varies between 40-80 km. It is situated at a height of 773 m meters above sea level. It is part of a series of East African Lakes – Nyasa, Kivu Rukwa and other formed by faulting of the African plate. Its area is about 33000 square km and deepest point – 1470 m. This is the second volume and depth freshwater lake in the world after Lake Baikal in Siberia.
The lake is divided between four countries – Burundi, Democratic Republic of Congo, Tanzania and Zambia, as the largest share of the Congo (45%) and Tanzania (41%). Lake water fall in the catchment area of the river Congo. In the past, Lake Tanganyika has been pouring out of the north in the Nile until the Virunga volcanoes do not block the flow in Rwanda.
Lake Baikal is of a tectonic origin, located in the southern part of Eastern Siberia, on the border between the Irkutsk region and the Republic of Buryatia. This is the deepest lake in the world and the largest natural reservoir of fresh water. The period of freezing lake is different (from 4.5 to 6.5 months) – almost whole lake freezes, except a small section 15-20 km long, located east of the Angara.
The period of navigation for passenger and cargo ships usually from June to September; Research vessels navigation starts immediately after clearing the ice and continues to freezing Baikal, i.e. from May to January.
In 1956 the lake becomes part of Irkutsk reservoir, with the result that the water level rises by almost 1 m.
