An environmental assessment of hydrocarbons in mid-Atlantic shelf sediments: 1975-1976 USGS-BLM program

During 1975-1976, the U.S. Geological Survey (U.S.G.S.), in conjunction with the Bureau of Land Management and the Virginia Institute of Marine Sciences, carried out an environmental assessment program to establish baseline concentration levels of hydrocarbons in the surface sediments of the Mid-Atlantic Shelf where leasing for petroleum exploration is anticipated. Reported here are the results of the individual hydrocarbon analyses for 150 composite surfacesediment samples.
