Abstract

The present study seeks to improve current understanding of modern climate changes, which are considered as the consequences of the greenhouse effect caused by increasing content of the main greenhouse gases – carbon dioxide and methane. Complex studies in the land–shelf–atmosphere system across the Arctic shelf, including biogeochemical and lithological analyses of sediments across Eastern Arctic seas, are needed. The research aims to study both lithological and mineralogical sediment compositions, variability of the organic matter content (C org ), molecular and isotopic composition of carbon (13C) contained in the ice complex deposits (ICD) along the Laptev Sea coast (Cape Muostakh). Samples of modern bottom sediments obtained during the expedition of 2015 in the south:eastern part of the Laptev Sea were investigated. Methods used in the present study include GC:MS analysis, pyrolysis, isotope analysis, X:ray phase analysis followed by further nume: rical processing and interpretation. Results. The mineralogical composition of the clay fraction has been studied, and the distribution of clay minerals has been established. The features of molecular and isotopic C org composition are revealed. Initial results on the hydrocarbon source of ICD:C org , which domi: nates in the shallow part of the East Siberian Arctic shelf, are obtained. Pyrolysis and GC:MS data are highly correlated reflecting com: plex biogeochemical processes occurring during the C org transformation at the various stages of lithogenesis. In addition, the study pro: vides preliminary estimates of the light hydrocarbons generation potential for the C org contained in the sediments.
