| Bathymetry GIS data | Echosounder | 10 m bathymetric contours for the Southwest Washington Study area based on NOS hydrographic survey data collected between 1926 and 1930 and supplemented with the southern part of the study area altered based on bathymetry collected on the CRLS 97007 cruise. Used as basemap data for surveying. | David C Twichell |

| uenhtif_sscan_SWWashington | Edgetech DF-1000 sidescan sonar | Enhanced sidescan-sonar TIFF images in a UTM projection on the inner continental shelf off the northern Oregon and southern Washington. Enhanced lines of sidescan imagery (since no mosaic was attempted), with a resolution of 2 m/pixel. The lines are widely spaced, hence the reason for no mosaic. Requires multiple files (total of 26 files) to cover the areas in 1997 and 1998. | David C Twichell |
