Abstract:

SWWA26PTS_SP is a point coverage containing digital hydrographic data collected off the coast of Southwest Washington and Northwest Oregon, USA. Horizontal datum is Washington State Plane South, Zone 5626 meters. The data set includes National Ocean Service (NOS) hydrographic surveys collected between the 1926 and 1928. It includes the most recent bathymetric data available on a regional scale over the inner to middle continental shelf off the coast of Washington and Oregon.

Purpose:

This data set is intended for use as an historical bathymetric data set for scientific research. It is not intended for navigational purposes. The data were originally used as part of the Southwest Washington Coastal Erosion Study (SWCES), a cooperative study by the US Geological Survey and the Washington State Department of Ecology.

Supplemental_Information:

The SWCES was initiated to examine coastal geology, processes, and natural hazards within the Columbia River littoral cell. The study is jointly directed by the U.S. Geological Survey Coastal and Marine Geology Program and the Washington State Department of Ecology Shorelands and Environmental Assistance Program, with active participation of local communities in Pacific and Grays Harbor counties. Related USGS work in the Southwest Washington Coastal Erosion Study can be found online at: <http://www.ecy.wa.gov/progra ms/sea/swce/>

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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The data have been thoroughly analyzed for for gross inaccuracies. A discussion of errors and accuracies associated with the original data collection methodologies can be found in Gibbs and Gelfenbaum (1999).

Logical_Consistency_Report:

Only NOS sounding data with an original cartographic code of 711 are included. The data set was rigorously edited of obviously erroneous points.

Completeness_Report:

Gaps in the hydrographic survey point data exists west of Willapa Bay from approximately -124.034 to -124.363 degrees longitude and 46.573 to 46.738 degrees latitude and northwest of Tillamook Bay from approximately -123.834 to -124.120 longitude and 45.472 to 45.626 latitude. The remaining data are considered complete.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Horizontal accuracies for NOS surveys vary by water depth and distance from shore (see Gibbs and Gelfenbaum, 1999).

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:: Vertical accuracies for NOS surveys vary by water depth and distance from shore (see Gibbs and Gelfenbaum, 1999).
