These dataset contains multi proxy data from short sediment core 16-KP-04-L19B obtained from Arctic glacial lake Rauchuagytgyn (N 67.7888, E 168.7380) by gravity coring during the Chukotka 2018 expedition (Siberia). We provide original count data of diatom species from 20 samples along a ca. 10.5 cm interval in the sediment core, next to organic carbon, nitrogen, and mercury concentrations. The data sets provides, calculated from the original data, estimated accumulation rates for diatom valves (diatom accumulation rate, DAR), organic carbon (organic carbon accumulation rates, OCAR), and mercury (Hg accumulation rates, HgAR). ... : Diatom valves were identified using a Zeiss Axioscope 5 light microscope with a Plan-Apochromat 100x/1.4 Oil Ph3 objective at 1000x magnification and Axiocam 208 color camera. ...
