Lake Tanganyika is the largest, by volume, of the East African Great 
Lakes with a maximum depth of 1.5 km. Surface energy fluxes were 
estimated from data collected on lake buoys with thermistor chains. The 
talk will illustrate how a gradient in meteorology along the length of 
the lake, driving a gradient in surface energy fluxes, results in a 
large-scale convective circulation, with currents in the surface layer 
against the dominant direction of the wind. The circulation may have 
slowed as the climate warmed over the past century. Changes in climate 
have affected productivity through effects on physical limnology in this 
deep tropical lake. The density gradient increased between shallow and 
deep water as the surface layer warmed more than deep water, resulting 
in reduced vertical mixing and circulation. The slow down of circulation 
has reduced internal nutrient loading to the epilimnion. The reduced 
mixing capacity of the lake between deep nutrient-rich bottom water and 
the oligotrophic epilimnion resulted in reduced primary productivity and 
reduced frequency of cyanobacteria blooms over the past century.
