Summary

This portion of the USGS data release presents gridded bathymetry data derived from repeated bathymetric surveys conducted by the U.S. Army Corps of Engineers Portland District on the Pacific Ocean, Washington. Repeated surveys were performed between September 9, 2020 and March 10, 2021 from a vessel equipped with a multi-beam bathymetry system to characterize the morphology and dispersal of a nearshore berm composed of sediment dredged from the navigational channel at the mouth of the Columbia River. Digital data files containing gridded bathymetry data for each survey are provided in ESRI ARC ASCII (*.asc) format.

Purpose

Bathymetry data were obtained characterize the morphology and dispersal of a nearshore berm composed of 216,000 cubic meters of sediment dredged from the navigational channel at the mouth of the Columbia River and placed outside the inlet in water depths between 12 and 15 m.
