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 is a collection of JPEG images generated by digitizing frames of video imagery taken of the seafloor. The video camera was mounted on the sediment grab sampler.

The quality of each image is dependant on bottom visibility at the time the video imagery was acquired. Completeness_Report: Video imagery was not acquired at every sample location. Various technical difficulties were encountered on the cruise which prevented the recording of video with every sample acquisition. In addition, not all sample stations had the seafloor visibility. In these cases, no video was digitized. Lineage: Process_Step: Process_Description: The original seafloor video imagery was stored on 8mm video tapes. Post-cruise processing included using a video frame grabber to digitize imagery corresponding to sediment samples. The video camera was mounted on the sediment grab sampler and acquired continuous color video before, during, and after sediment sample collection. The images were digitized post-cruise into a color TIF image format and then converted to an 8-bit grayscale image. The grayscale images were not only much smaller, but actually showed better contrast when looking at seafloor morphology features. These images were also enhanced in an attempt to further accentuate the seafloor morphology features. To further descrease file size, these TIF images were then converted to JPEG format.

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 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.

Each image corresponds to a sediment sample location. The image filename corresponds to the Samp-id attribute of the 'grabsamp' ArcView shapefile. Location of actual video imagery is in close proximity to the sediment sample location. Direct_Spatial_Reference_Method: Raster Raster_Object_Information: Raster_Object_Type: Pixel Entity_and_Attribute_Information: Detailed_Description: Entity_Type: Entity_Type_Label: digitization of seafloor bottom video Entity_Type_Definition: JPEG image Entity_Type_Definition_Source: none Attribute: Attribute_Label: Filename Attribute_Definition: The image filename corresponds to a sediment sample. For example, 'sta71-1.jpg' refers to the digital seafloor image that corresponds to grab sample number 71. The -1 refers to the first image digitized, a -2 or higher number indicates subsequent digitized video images. In some cases, an image was saved in both grayscale and color. This is indicated by the presence of a "c" in the filename. For example, 'sta72-2c.jpg' is the second digitized video image, in color, that corresponds to sediment sample number 72.
