Description:
Abstract:
This is a digital data set including historical hydrographic data collected off the coast of Southwest Washington and Northwest Oregon, USA. The data set is a composite of numerous hydrographic surveys collected by the National Ocean Service and U.S. Army Corps of Engineers between 1926 and 1941. Offshore data have been evaluated for errors and inconsistencies and erroneous points have been removed. Estuary data have not been evaluated. Horizontal datum is Washington State Plane South Fipzone 4602 meters. Attributes inlcude easting, northing, depth-navd(m), depth-mllw(m), and original survey name.

Individual surveys in this combined data set include: GH27ANC, H04611, H04612, H04618, H04619, H04620, H04621, H04633, H04634, H04635, H04636, H04658, H04710, H04715, H04716, H04728, H04729, H04735, H05927, H05928, H05975, H05976, H06178, H06179, H06180, H06181, H06182, H06237, H06514, H06515, H06516, H06517, H06518, H06519, H06520, H06521, H06646, H06647, H06665, and MCR1935.

Purpose:
This data set is intended for use as an historical bathymetric data set for scientific research. It is not intended for navigational use. The data were originally used for bathymetric change analysis 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.

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:
All sounding data equal to -9999 and/or with an original NOS cartographic code not equal to 711 were eliminated from the data set. The data set was evaluated for gross inaccuracies and points that were obviously erroneous were removed. from this data set.
Completeness_Report: The data set is 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).
