Sixteen digital bathymetric surface models (grids) of the seafloor off the coast of Washington and Oregon were created for wave modeling experiments along the coast of Washington. Surfaces were created for two areas over two time periods. The largest area (covering approximately 46 million km 2) extends along the coast of Oregon and Washington, between Heceta Head OR and Cape Johnson WA, from the shoreline to about 2000-m water depth (hereafter referred to as the ORWA region; Fig. 1). The second area (covering approximately 7 million km 2) extends from Tillamook Head OR to Pt. Grenville WA, from the shore to approximately 700-m water depth. This area corresponds to the study area boundaries of the Southwest Washington Coastal Erosion Study (Kaminsky et al., 1997, Gelfenbaum and Kaminsky, 1998; 1999) and is hereafter referred to as the SWWA region (Fig. 2). Surfaces defined by the ORWA and SWWA regions were created for two time periods; historical (circa 1926), and modern (a combination of c.1926 and 1998 as discussed below). Data are presented in both UTM and Washington State Plane South coordinate systems, at 500-m and 750-m grid cell spacing, in ARC/INFO 7.1 (ESRI), SURFER 6.0 (Golden Software), and ASCII formats. The vertical datum is mean lower low water (MLLW).
This report describes the data sets used and the methodology and techniques applied to create the historical and modern bathymetric surfaces. The data included in this report are intended for scientific research and should not be used for navigational purposes. The use of trade names or products does not imply endorsement by the U.S. Geological Survey.
This work was conducted in conjunction with the Southwest Washington Coastal Erosion Study (SWCES), a cooperative project directed by the U.S. Geological Survey, Coastal and Marine Geology Program and the Washington State Department of Ecology. A description of the study and initial results can be found in Kaminsky et al. (1997) and Gelfenbaum and Kaminsky (1998 and 1999).
