Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 04:40 AM | Dataset Last Updated: April 17, 2024 at 12:00 AM
This portion of the data release presents sediment grain-size data from cores and surface samples collected from the Salmon River estuary in 2017 and 2018. In total, 60 samples were collected from 18 sites containing sandy sediment from the circa 1700 CE tsunami deposit, two sites with post-1700 CE silt, and eight modern surface sample sites. The grain-size distributions of samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. The grain-size data are provided in a comma-separated values (.csv) text file.
