Verification of Remote Sensing Data for Determining the Nature of Hydrocarbons (a Case Study of the Barents Sea)

Using the remote sensing data obtained by the Sentinel-1A and Sentinel-1B satellites in the years 2016–2021, a local accumulation of oil slicks in the Barents Sea in 53 synthetic aperture radar images is delineated in the area with coordinates 75.2°–75.3° N and 31.5°–31.8° E. The study of an undistu...

Description
Summary:Using the remote sensing data obtained by the Sentinel-1A and Sentinel-1B satellites in the years 2016–2021, a local accumulation of oil slicks in the Barents Sea in 53 synthetic aperture radar images is delineated in the area with coordinates 75.2°–75.3° N and 31.5°–31.8° E. The study of an undisturbed core in this area (station 7105, 84th cruise of the R/V Akademik Mstislav Keldysh ) has shown an anomalous distribution of polycyclic aromatic hydrocarbons, PAHs, the concentrations of which increased at the lower horizons of the column, and 2-methylnaphthalene, a marker of oil genesis, dominated in their composition; at the same time, the share of light homologs in the composition of alkanes increased. All this points to the natural formation of hydrocarbons in the sea bottom sediments, and it is definite that the group of oil slicks detected from the satellite radar data is a natural oil seep.
