220 surface sediments, gas chromatography, mass spectrometry, bitumen extracts. One station in southeastern Bering Sea and two stations in lower Cook Inlet display n-alkanes and triterpenoid distribution typical of weathered petroleum. Major faulting and oil production could contribute petroleum hydrocarbons to the sediments. Apart from these stations, there is little evidence of near-surface petroleum seeps in the sites investigated.--Modified journal abstract.
