The data described here are part of a data release of sixteen bathymetric surface grids. These include: 1926 regional and study area grids and 1926-1998 merged regional and study area grids, each at 500m and 750m grid spacing, in UTM(m) and Washington State Plane(m) projections. The regional data set extends from near Heceta Head, Oregon to Cape Johnson, Washington, from the shoreline to about -2000m; the study area data set extends from Tillamook Head Oregon to Pt. Grenville WA, from the shore to approx. ~-700m water depth. Please refer to Gibbs, 2000 for details.
