Grain Size Data from the NOAA Outer Continental Shelf Environmental Assessment Program (OCSEAP)

browse graphicsample locations in study area
This 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).

Use Constraints
  • While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

Source Datasets
Lineage Statement Sample collection, laboratory analysis, and translation of data into the 073 grain size format were performed by the originator. OCSEAP grain size data were submitted to the former National Oceanographic Data Center (NODC) as part of a larger study. NODC forwarded the data to the former National Geophysical Data Center (NGDC) as the archive responsible for sediment analyses. Copies of OCSEAP grain size data may exist in the oceanographic archive, as well as the geophysical archive. Both NODC and NGDC are now part of NOAA's National Centers for Environmental Information (NCEI).
