Samples from the United States eastern continental margin collected by the U.S. Geological Survey

As part of the National Geophysical and Solar-Terrestrial Data Center's (NGSDC's) project to maintain a computer-accessed list of marine geological samples, the U.S. Geological Survey has inventoried 3,949 samples from the continental margin of the Eastern United States (Fig. 1). Most (3,868) of these samples are grab and dredge samples collected by the U.S. Geological Survey in an earlier cooperative program with the Woods Hole Oceanographic Institution (WHOI) and are stored at WHOI. Samples collected since 1974 are stored by the U.S. Geological Survey. This more recent collection is made up of 3,815.5 m of rotary-drilled cores collected at 19 stations in 1976 by the drill ship GLOMAR CONCEPTION, 243.8 m of piston cores and 38.3 m of gravity cores collected during the 1979 and 1980 cruises of the R/V ENDEAVOR, and &grab samples collected by the M/V STATE ARROW in 1978.
