Summary

SWWA98_500UTM is a digital bathymetric surface grid of the seafloor offthe coast of Southwest Washington and Northwest Oregon.Grid cell spacing is 500m and the projection is UTM Zone 10.The surface grid was produced by merging National Ocean Service (NOS)Hydrographic Surveys conducted between 1926 and 1927 with recentsurveys conducted by the U.S. Army Corps of Engineers (USACE) in 1998around the entrances to Grays Harbor, Willapa Bay, and the ColumbiaRiver. The results of this work represent the best available estimate ofthe seafloor morphology for the time period circa 1998. Theuser is cautioned, however, to use this data set with full knowledge ofthe original intent, the limitations, and assumptions used to generate it.

Purpose

This bathymetric surface grid is intended for use as a modern bathymetricbase map for scientific research. It is not intended for navigationalpurposes. The grid was originally intended for use in wave modellingexperiments as part of the Southwest Washington Coastal Erosion Study(SWCES), a cooperative study by the US Geological Survey and theWashington State Department of Ecology.
