The dry season is characterised by nearly constant high southeasterly winds, while for the rest of the year mild wind blows generally from the northeast. Lake Tanganyika is one of the African Great Lakes and the world's second oldest freshwater lake. Core LT17-2A (yellow dot) was collected from an outer ramp depositional setting (~420-m water depth) in Lake Tanganyika’s southern basin. Lake Tanganyika is the second largest fresh water lake in the world by volume and the second deepest lake after Lake Baikal in Siberia. Other large lakes appear in black, and several support important regional fisheries. That makes it the second deepest freshwater lake in the world. In dimensions, it is estimated to be the longest lake in the world with its 660 kms length and second deepest lake by its 1436 meters depth. Its mean depth is 570 m but it has a maximum depth of about 1470 m in the northern basin. Its volume measures approx. Lake Tanganyika is located to the east of central Africa, and is shared by four developing countries: Democratic Republic of the Congo, Burundi, Tanzania, and Zambia. However, it helps to establish a boundary between the Democratic Republic of the Congo, Burundi, and Zambia. The lake holds at least 250 species of cichlid fish and 75 species of non-cichlid fish, most of which live along the shoreline down to a depth of approximately 180 metres (590 ft). In spite of the majority of its water column being anoxic, Tanganyika hosts some of the most diverse and prolific fisheries and ecosystems on Earth. The lake is anoxic below - 150-m depth. INFORMATION ABOUT BIOTOPE. The project which began in 1995 comes to an end in the year 2000 and is funded by the Global Environmental Facility through United Nations Development Programme (UNDP). Lake Tanganyika caters for the water needs of more than 50 million people in four countries including Tanzania, Burundi, the Democratic Republic of Congo and Zambia. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases after Lake Baikal in Siberia. ... Lake Tanganyika is located in Africa’s Western Great Rift Valley, between the latitudes of 03˚20’ and 08˚48’ South and the longitudes of 29˚03’ and 31˚12’ East (Figure 1). With a maximum depth of 1470 m and an area of 32 900 km² , Tanganyika is the second deepest and the fifth largest lake on the planet. The clear water visibility is about 49 feet and the species of fish make the lake ideal for snorkeling and diving. An analysis is presented of the wind-induced thermocline oscillations of Lake Tanganyika, East Africa. As Lake Tanganyika is a border for four countries Zambia, Burundi, Democratic Republic of Congo- the success of the project will depend on how well these countries work together. Specifically in Lake Tanganyika, the evolution of stenotopy regarding depth, bottom type, or light intensity may have been prohibited by the seasonal upwelling of anoxic waters . Lake Tanganyika is situated in Eastern Africa. Lake Tanganyika was first brought to the attention of Europeans in February 1858 when English explorers were trying to find the source of the great Nile River. At its depth, Lake Tanganyika stretches 1,470m; the second deepest freshwater lake … 18,880 cubic kilometres and its maximum depth lies at 1,470 m. With a maximum length of 673 km and a maximum width of 72 km, Lake Tanganyika covers a surface of 32,893 sq. Lake Tanganyika Agriculture & Biology Unlike many other tropical lakes, there are rarely secondary thermoclines above the main one, although daily stratification of the first 5-10 meters under the immediate influence of the sun may occur (Hecky, 1991). The lake holds at least 250 species of cichlid fish and 75 species of non-cichlid fish, most of which live along the shoreline down to a depth of approximately 180 metres (590 ft). The water is known for its clear appearance, rich soil, and warm temperatures. Comparatively narrow, varying in width from 10 to 45 miles (16 to 72 km), it covers However, recent data shows that the depth of this Lake – which is located west of Tanzania, north of Zambia and east of both the DR Congo and Burundi – has decreased by 1.5 cubic meters, something which is causing major concerns. Lake Tanganyika shows pcrmancnt thermal stratification with deep-water temperatures that have been stable over the period of observation (since 1939). Photosynthetic picoplankton in Lake Tanganyika: Biomass distribution patterns with depth, season and basin Lake Tanganyika, second largest of the lakes of eastern Africa. With an area of 32,900 km 2, a maximum depth of 1,470 m, and a volume of 18,880 km 3, Lake Tanganyika qualifies simultaneously as: . Lake Tanganyika is an African Great Lake. Lake Tanganyika is a large lake in central Africa (3° 20' to 8° 48' South and from 29° 5' to 31° 15' East). Lake Tanganyika has over 350 species of fish, of which most are endemic. Average concentration (µM) of soluble reactive phosphorus, dissolved inorganic nitrogen and dissolved reactive silica at 0, 20, 40, 60, 80 and 100 m depth during the wet and dry seasons, in the north and south basins of Lake Tanganyika, with standard deviations (for readability, only the positive standard deviations are shown, and depth values are slightly shifted forward). The lake holds at least 250 species of cichlid fish and 150 non-cichlid species, most of which live along the shoreline down to a depth of approximately 600 feet). Its volume of 18 880 km³ makes it the third largest lake in the world by volume, exceeded only by the Caspian and Baikal. Together they form a unique fingerprint. It is the longest freshwater lake in the world (410 miles [660 km]) and the second deepest (4,710 feet [1,436 metres]) after Lake Baikal in Russia. Stretching 420 miles, this lake is the longest freshwater lake in the world and has a maximum width of 31 miles wide and an astounding depth of 4,708 feet. Lake Tanganyika is permanently stratified with the depth of the thermocline varying each year and each season but generally being around 100-200 m deep. Fingerprint Dive into the research topics of 'Lake-level history of Lake Tanganyika, East Africa, for the past 2500 years based on ostracode-inferred water-depth reconstruction'. Lake Tanganyika, the largest tropical freshwater lake and the second largest by volume on Earth is characterized by strong oxygen and redox gradients. The expedition in Lake Tanganyika was conducted with permission from the Zambian Ministry of Agriculture, Food, and Fisheries and complied with the current laws of Zambia. 1. The water temperatures in Lake Tanganyika range between 75–77°F (24–25°C). Lake Kivu (2,220 square kilometres (860 sq mi), elevation 1,460 metres (4,790 ft)) empties into Lake Tanganyika via the Ruzizi River.
