Tasks:
IZ-BAS undertakes all field sampling at the Classification
and Validation lakes in the Bulgarian Rila Mountains, and assists
UIBK-IZL and ECRC-UCL with the collection of
sediment cores, fish and catchment-based determinations from sites
in this region. IZ-BAS undertakes the following analyses from
Bulgarian sites: water chemistry; phytoplankton; zooplankton;
zoobenthos of the lakes and their inflows and outflows;
ichthiology; and primary production/photosyntethic pigments.
