n-Alkanes, total organic carbon content, radiocarbon ages, grain size distribution, biogeochemical and hydrochemical parameters of sediment core beneath thermokarst lake Goltsovoye Lake on the Bykovsky Pensinula, northeastern Siberia
These datasets describe a 31.5 m long sediment core taken from beneath thermokarst lake Goltsovoye Lake (71.74515 N, 129.30217 E) on the Bykovsky Peninsula, northeastern Siberia. The thermokarst lake was 510 cm deep. Here, we report the depths from the ice surface as well as from the sediment surfac...
