Abstract—

This paper discusses the results of comprehensive geological, geophysical, and geochemical studies of gas-saturated sediments within the Kandalaksha Bay, the White Sea. The marine study involved detailed seismoacoustic surveys that yielded data on seabed geometry and the geological structure of the sedimentary cover, including the zones of focused unloading of hydrocarbon fluids. Assemblages of gas caps are confined to the zones with a maximum thickness of postglacial sediments. The composition of organic matter in the sediments and the gas phase has been studied in detail.

Keywords:

Kandalaksha Bay White Sea seismoacoustic survey gas-saturated deposits bottom sampling geochemical survey and hydrocarbon gases
