Datasets that provide high-resolution palaeoenvironmental information during the last glacial maximum in Chukotka, Arctic Siberia are limited. This data compilation comprises multiproxy data extracted from sediment core EN18218 obtained from Arctic glacial lake Rauchuagytgyn (67.7922°N, 168.7312°E) by piston coring during the Chukotka 2018 expedition. The dataset covers the late Pleistocene and Holocene (ca. 29 cal. ka BP). Observations within this dataset include 14C radiocarbon dates, hydrochemistry observations, sedimentological observations (water content, bulk density, grain-size, sediment color, biogeochemistry (Total sulphur (TS), Total carbon (TC), Total organic carbon (TOC), Total inorganic carbon (TIC)), X-ray fluorescence (XRF) based sediment-geochemistry and magnetic susceptibility measurements. Radiocarbon dating was performed with accelerator mass spectrometry (AMS) using the Mini Carbon Dating System (MICADAS) at AWI Bremerhaven, Germany. Water content and bulk density were measured according ...
