Grain Size Data from the NOAA Outer Continental Shelf Environmental Assessment Program (OCSEAP)
browse graphicThis data set contains grain size data from samples acquired under the NOAA Outer Continental Shelf Environmental Assessment Program (OCSEAP) from the Outer Continental Shelf around Alaska. Data were contributed by the University of Alaska, the University of South Carolina, the Scripps Institution of Oceanography, and the US Geological Survey with funding from NOAA. Data fields include collecting institution, ship, cruise, sample id, latitude/longitude, date of collection, water depth, sampling device, method of analysis, sample weight, sampled interval, raw weight percentages of sediment, within a given phi range. Some samples also have percentages of total gravel, sand, silt, clay, and statistical measurements such as mean, median, skewness, kurtosis, and standard deviation of grain size. These data are part of the larger NGDC Seafloor Sediment Grain Size Database (doi:10.7289/V5G44N6W).
