Description:
Abstract:
This is a digital data set including historical hydrographic sounding data collected by the National Ocean Service (formerly the U.S. Coast and Geodetic Survey) within the Columbia River littoral cell (CRLC). The original data set has not been edited or evaluated for inconsistencies. The original chart has an unknown horizontal datum. A datum of NAD27 was assumed in order to reproject the data to Washington Stateplane, FIPS 4602, meters. Attributes inlcude easting, northing, depth-navd(m), depth-mllw(m), cartographic code, survey name, and survey year.
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 intended to be 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:
This survey has an unknown horizontal datum. The data have not been thoroughly analyzed for for gross inaccuracies or inconsistencies. 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 not evaluated for obviously erroneous points or inconsistencies.
Completeness_Report: The data set is considered complete.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
This survey has an unknown horizontal datum. 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:
Information from the original chart suggests that the vertical datum is probably the lowest tide observed which is approximately 1.5 feet below MLLW. No corrections were made for the difference between chart datum and MLLW. Vertical accuracies for NOS surveys vary by water depth and distance from shore (see Gibbs and Gelfenbaum, 1999).

Data were originally digitized by NGDC and provided to the SWWCES under contract to USGS. Data area now available on this CD-ROM. Data included here were aquired directly from NGDC and not off the CD-ROM. Some differences may exist.
Process_Step:
Process_Description:
Data were reprojected from geographic coordinates, (assumed NAD27 although the original chart has an unknown horizontal datum) to Washington Stateplane-NAD83, FIPS 4602. No additional error analysis or editing was done.

Water depth relative to NAVD88 was calculated by first determining the primary tidal station used for a particular survey. This information was obtained from original smooth sheets and/or descriptive reports where possible, or assumed where such information didn't exist. Relative offsets between MLLW and NAVD88 at each tidal station was determined based on geodetic information provided for NOS benchmarks, determined by independent geodetic surveys conducted by the Department of Ecology, or estimated where no other information was available. The NAVD88 values were thus calucalated by adding the relative differences between datums to the MLLW depth values. In some cases, a larger datum correction was applied to offset obvious bias in the original data set. An in-depth description of the methodolgy employed for these conversions, along with a discussion of specific corrections made, are available in Buijsman, et al., 2002.

DATA SET SPECIFIC INFORMATION:

For the data set: h335_1852 The primary tidal station used is: ASTORIA, assumed The source used to determine the tidal station: No direct information was available regarding this survey. The vertical datum relative to NAVD88 is: -0.02 meters The conversion applied to charted depths: -0.02 meters

Data from this survey was aquired from NGDC relative to an unknown horizontal datum. A datum of NAD27 was assumed in order to project the data into WA Stateplane. The registration problem was not investigated in depth, nor was the data set evaluated for inconsistencies or errors. This survey was not included in any combined data sets or used for bathymetric analyses.

Information from the original chart suggests that the vertical datum is probably the lowest tide observed which is approximately 1.5 feet below MLLW.
