These cruises aboard the R/V Corliss were run in order to generate reconnaissance maps of the seafloor geology and the shallow subsurface stratigraphy using sidescan-sonar and seismic-reflection mapping techniques. The 1998 cruise also collected sediment grab samples, bottom photographs, and video images to verify the sidescan-sonar imagery and to document the seafloor geology. The combination of these data with previously collected sediment sample data (Robert, 1974; Nittrouer, 1978; and Smith et. al., 1980) has been used to define the extent and lithology of shelf sediments associated with the Columbia River littoral cell. This work is one component of a larger project studying the erosion of the Washington Oregon coasts and is being coordinated by the U.S. Geological Survey and the Washington State Department of Ecology. The reasons for collecting these data are to provide a regional synthesis of the offshore geology for this project and to support a wide variety of management decisions and to provide a basis for further process-oriented investigations. Purpose: This GIS overlay contains sediment sample locations and analyses information collected aboard the R/V Corliss in 1998.

Completeness_Report: All sediment samples acquired on the cruise CRLS98014 are presented in this dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These navigational points actually represent the ship's position. No instrumentation was on board to give the sediment sampler's position while on the seafloor. However, most of the samples were taken in fairly shallow water, therefore the potential for ship offset due to wire angle is minimized. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Although depth measurements were taken with an Odem fathometer, the criteria for taking these measurements is not particularly strict. A rough estimate of vertical accuracy is +/- 1 meter. Lineage: Process_Step: Process_Description: The sediment sample locations and associated sample identification were logged shipboard. Sediment analyses were performed in the USGS Woods Hole sediment lab. This analyses information was then joined to the sediment sample location in ArcInfo. The data were then converted to ArcView shapefiles. Process_Date: 1998 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: VeeAnn A.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The original metadata was available in HTML only, so had to be reformatted. The citation in the identification section was completely redone, including adding links to the data and larger work citation. Added ISO 19115 Topic Category keywords. The standard order process section in the distribution was modified to include the link to the data. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
