TY - Data T1 - Geochemistry of sediments from Arctic thermokarst lakes and lagoons on the Bykovsky Peninsula, Siberia A1 - None DO - 10.5880/GFZ.3.7.2022.001 PY - 2023 DA - 2023-05-29 PB - National Cryosphere Desert Data Center AB - In the permafrost regions along the Arctic coast, thermal reef lagoons represent the transitional state from freshwater lakes to marine environments. The transition state from freshwater lakes to marine environments has received little attention in terms of its impact on greenhouse gas production and release. The role of greenhouse gas generation and release has received little attention. The geochemical characteristics of a hot carbonate lake were compared with those of two hot carbonate lakes. Comparison was made with two hot karst lakes on the Bykovsky Peninsula in northeastern Siberia. This dataset includes pH values, major cations and anions, alkalinity, salinity, and dissolved iron (iron and ferrous). The concentration of pore water in sediments of lakes and lagoons; The concentration and stable isotope characteristics of CH4in the small plug sample.The concentration and stable isotope characteristics of CH4 in small plug samples of sediment cores; Total carbon (TC), total organic carbon (TOC), total nitrogen (TOC), total nitrogen (TN), and total sulfur (TS); And some biomarker indices (such as biomarkers on lakes and atolls). Calculate biomarker indices (such as CPI, Paq) based on the concentration of n-alkanes to describe the sources of organic matter in sediments. The source of organic matter (OM) in lakes.The dataset is compiled into an Excel file, with samples in rows and environment parameters in columns.
