Short summary
Even minor hydrocarbon seepage from reservoirs into overlying seafloor can affect marine sediment biogeochemistry. Our analysis of 50 sediment cores from the Barents Sea revealed that subtle seepage alters chemical balances and stimulates carbonate and sulfide mineral formation. The cores also showed strong local and spatial variation, highlighting patchy migration pathways. Minerals and pore water chemistry together provide clues to identify both past and ongoing seepage activity.
