This dataset is a compilation of over 27,000 sediment samples from many cruises conducted by the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center over the period from 1955 to 2014. Information contained in the data includes sampling device and depth, as well as locational and project-related information. Additional information on grain size fractions and statistics are also included. Please note the original USGS data download contains all the sample points in its sediment texture database. The layer shown in the map service only contains the samples in U.S. waters.
