AB  - The recent intensification of energy resource exploration and human activities in 
      the Barents Sea (BS) requires a more thorough assessment of the natural and 
      anthropogenic impact of hydrocarbons on the environment. We analyzed a wide set 
      of sensitive indicators, including hydrocarbon molecular markers and organic 
      matter (OM) maturity parameters in the Holocene sediments from three regions of 
      the BS: the Kola-Kanin Monocline (KKM), the Svalbard shelf, and the Shtokman 
      gas-condensate field (GCF). An increase in pyrogenic polycyclic aromatic 
      hydrocarbons toward the core surface traces the intensification of anthropogenic 
      contamination in the KKM region during last century. An input of highly mature OM 
      from the eroded coal rocks of Barentsburg were confirmed by comparison of 
      biomarker distribution in sediments and coals. An increase in biogenic hopanes 
      and hopenes content down-core, and a crude-oil stage of OM maturity in surface 
      sediments of the Shtokman GCF attests to hydrocarbons migration from subsurface 
      strata.
