Acoustic attenuation in Lake Tanganyika

Nature, 1979
THE Lake Tanganyika acoustic attenuation experiment of April 1970 (ref. 1) was the second of two lake experiments designed to help identify the cause of the low-frequency attenuation anomaly in seawater by providing comparative freshwater data. Although the Lake Tanganyika results showed no evidence of the anomaly, the attenuation was unaccountably ...

The heat on Lake Tanganyika

Nature, 2003
Warming of surface waters and declining fish catches in Lake Tanganyika have been linked to global climate change. The impact of global warming on natural ecosystems may be starting to affect local economies.

External Nutrient Sources for Lake Tanganyika

Journal of Great Lakes Research, 2003
This study assessed the external nutrient sources for Lake Tanganyika from August 1994 to August 1995. The physico-chemical characteristics of the three largest inflowing rivers (Rusizi, Malagarasi, and Lufubu) and the wet atmospheric deposition in Bujumbura (Burundi), Kigoma (Tanzania), and Mpulungu (Zambia) were analyzed.

Lake Tanganyika and its Life

Trends in Ecology & Evolution, 1991
Abstract Lake Tanganyika, situated in the western rift system of East Africa, is the largest in volume of the African Great Lakes and the second deepest lake in the world. It is extremely ancient in comparison with most lakes. The aquatic flora and fauna are remarkable for their diversity and high degree of endemicity, as well as for the

Diurnal winds around lake Tanganyika

Quarterly Journal of the Royal Meteorological Society, 1997
AbstractRegular diurnal variations of coastal winds are observed around Lake Tanganyika during the dry season, when insolation is intense and the prevailing trade winds are weak. the long deep lake is at the bottom of the East African rift valley. A two‐dimensional mesoscale model across the schematic rift‐valley topography is used to study these local

Lake Tanganyika Sound Attenuation Experiment

Nature Physical Science, 1972
MEASUREMENTS of the attenuation of low-frequency sound in seawater (Fig. 1) show anomalously high values of attenuation below 10 kHz (ref. 1). The explanations of this anomaly include biological and particulate scattering, nonlinear propagational effects and chemical relaxation phenomena2 but because insufficient experimental evidence exists, a ...

Gastritis in Lake Tanganyika cichlids (Tropheus duboisii)

Veterinary Record, 1985
Necrotic and granulomatous gastritis is described in Lake Tanganyika cichlids. Clostridium hastiforme and flagellated protozoa were both associated with the reaction but the significance of either is unknown. Nevertheless, treatment of surviving fish with ampicillin was carried out and mortalities ceased.

Lake Tanganyika ecosystem management strategies

Aquatic Ecosystem Health & Management, 2008
Lake Tanganyika is a large East African rift valley system holding about 1/6 of the world's liquid freshwater with about 2000 species of organisms (fauna and flora), of which about 700 are endemic. The lake faces a number of threats including excess sedimentation, overfishing, pollution, habitat destruction, along with climate change. Efforts to better

The Prosobranchs of Lake Tanganyika

Nature, 1938
WHEN Sir Richard Burton discovered Lake Tanganyika in 1858 his companion, Speke, collected a number of shells from the shores. These proved to be Prosobranchs of types hitherto unknown in fresh water. Later investigations, notably those of the three Tanganyika expeditions, the first two under the leadership of J. E. S.
