Pore water solutes, total cell counts, dissolved gases and sulfate reduction rates of the 50 gravity cores of the PROSPECTOMICS project

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: pore water geochemistry (IC, ICP-MS, titration and spectrophotometry); dissolved gas concentrations (GC) and total cell counts (fluorescence optical microscopy).
