Results from sub-bottom profiling in the lakes Taymyr and Levinson Lessing, presented in
this book, indicate that glaciers were present in the western Byrranga Mountains for the last
time during the Early Weichselian glacial (Niessen et aI., this volume). In addition, the seismic
data are discussed with respect to the postglacial depositional histories of these lakes, with
particular attention to their dependence on lake-level fluctuations. Sedimentological data from
the Levinson-Lessing Lake core support the seismic interpretation and supply more detailed
information concerning the kind and temporal variations of sedimentary processes since late
Middle Weichselian time (Ebel et a!., this volume).
Palynological analyses on sediment cores from four lakes, forming a transect from the
southern Taymyr Peninsula to Severnaya Zemlya, were employed to reconstruct the vegetation
history in the catchment areas of the lakes since Middle to Late Weichselian times (Hahne and
Melles, this volume). The palynological results, compared with published ice core isotope data
from Severnaya Zemlya, give a first impression of the development and of spatial and temporal
variations of vegetation zones in dependence on climatic changes since the latest Pleistocene.
The Holocene climatic evolution at the Lama Lake is also mirrored by the planktonic to
benthonic diatom ratio in the lake sediments (Kienel, this volume). In addition, the diatom
assemblages enable to reconstruct variations in the trophic conditions in the lake water.
Hagedorn et al. (this volume) used 210Pb dating and measurements of heavy metal
concentrations in near-surface sediments of the Lama Lake to determine geogenic and
anthropogenic sources and calculate recent accumulation rates.
