| Hand-grab sample | --- | Biology Chemistry Geology | Surface-sediment grain-size distributions of the Elwha River delta, Washington, July and August 2023 (Surface-sediment grain-size data are derived from samples collected on the Elwha River delta, Washington, in July and August 2023 (USGS Field Activity 2023-645-FA). Surface sediment was collected from 76 locations using a small ponar, or 'grab', sampler from the R/V Dogfish in water depths between about 1 and 17 m around the delta. An additional 18 samples were collected by hand at low tide. The grain size distributions of suitable samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab.) |
