Methane formation and distribution of acoustic turbidity in organic-rich surface sediments in the Arkona Basin, Baltic Sea

摘要

This study was performed to investigate gas formation and gas saturation conditions related to acoustic turbidity in shallow (similar to 40m deep) marine basins. The Arkona Basin, Baltic Sea, with its organic-rich fine-grained surface sediment provides an ideal "Natural Laboratory" to characterise free gas using seismic, geoacoustic, and geochemical methods.
