Sediment grain size in the Elwha River estuary, Washington, from 2013 and 2014.
Description
This portion of the data release presents sediment grain-size data from samples collected in the Elwha River estuary, Washington, in July 2013 and June 2014 (USGS Field Activities L-15-13-PS and 2014-628-FA). Surface sediment was collected from one location in 2013 and five locations in 2014 using a using a push core. The locations of grab samples were determined with a hand-held global positioning system (GPS). The cores were split into one- to three-centimeter sections. The grain-size distributions of samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. Size fractions are defined as gravel (greater than 2 mm), sand (63 micron to 2 mm), silt (4 micron to 63 micron), clay (less than 4 micron), and mud (less than 63 micron). The grain-size data are provided in a comma-delimited spreadsheet (.csv).
