Abstract

The paper presents data on concentrations and composition of hydrocarbons (HCs) including aliphatic hydrocarbons (AHCs) and polycyclic aromatic hydrocarbons (PAHs) in ice, surface microlayer (SML up to 1000 μm thick), and surface waters of the Barents and Kara Seas (96th cruise of the R/V Akademik Mstislav Keldysh, July–August 2024). Due to the higher water content of ice, it weakly accumulates HCs in comparison with surface waters and SML. The influence of autochthonous processes on the composition of alkanes in ice and SML is minor and differs from their composition in the multi-year ice. In spite of different sources of these HC classes, all samples exhibit a correlation between the AHCs and PAHs in the SML suspension (r = 0.67, р = 0.05).
