Abstract:

During an expedition to the southern Barents Sea in 2021, 50 gravity cores were collected at about 350 m water depth at three sampling areas with known underlying hydrocarbon reservoirs (i.e. Zone 1, Zone 10, Zone 12) and two reference areas (i.e. Ref 5, Ref 6). The cores were subsampled on board and further analyzed for bulk sediment elemental composition (XRF spectrometry).
