Two biological surveys were carried out on Lake Tanganyika. The first cruise was at the end of the wet season (April-May) when phytoplankton biomass was low and the second was at the end of the dry season (September-October) when biomass was high. The parameters measured were: temperature profiles, Secchi disk and quantum meter transparencies, chlorophyll, major ions and nutrients, phytoplankton, bacterial and protozoan biomass, primary production, plankton respiration rates, methane concentration profiles and methane oxidation rates.
