Lake Sediment Coring in Turkey

Dr Martin Kernan and Dr Simon Turner joined colleagues from Middle Eastern Technical University (METU), Ankara, to take sediment cores from three large shallow lakes in western Turkey; Lakes Bey┼čehir, Marmara and Uluabat. UCL and METU will use palaeolimnological techniques, employing biologicial remains and geochemistry, in studying the sedimentary record. This will allow them to reconstruct changes in salinity, nutrient state and trophic structure related to major changes in water level in the past century. The aim of this work is to support assessments of the ecological consequences of lowered lake levels arising from the combined effects of climate change and abstraction for irrigation.
