Investigations of lake sediments and limno-monitoring

Lake sediment investigations are currently concentrating on lake Chatyr-Kul in estern Kyrgyzstan, and on the Sary-Chelek Lake in the Chatkal Mountain Range (W-Kyrgyzstan), which has over 200 meter water depth and formed by a huge landslide of unknown age.

From various sub-basins of the Sary-Chelek short gravity cores were obtained with varved sediments. A thick slump found at the base of the cores is most likely caused by a major historical earthquake (Chatkal 1946 AD). As part of student qualification work, the landslide damming the Sary-Chelek, and some associated smaller lakes are currently being examined in more detail. Since 2013, various limnological and meteorological parameters have been measured in and around the Sary-Chelek. These data sets are used to understand the current dynamics of the lake and the paleoclimate proxy data obtained from lake sediments. With its seasonally stratified sediments the Sary-Chelek is a unique climate archive in the region and is to be examined in an even more intensive limnological and sedimentological manner in the future.
