Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: These data are interpretative. They are accurate according to geologic interpretations made by scientists at the USGS, Woods Hole Field Center. These interpretations were based on acquired high-resolution seismic reflection, sidescan-sonar, and surficial core and sample information. Logical_Consistency_Report: These data are associated with high-resolution seismic reflection, sidescan-sonar, and surficial sediment core and sample data. They are consistent within their assocations with these data. Completeness_Report: These data are complete. These data were published within USGS Open-File Report 00-295. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. 99% of the positional data is DGPS. Unless noted, all GPS/DGPS data is referenced to WGS84 (NAD83). Slant-range distance is recorded between the sidescan-sonar tow vehicle and a sidemount rigged with an acoustic transponder. Offset between the sidemount and GPS antennae is measured. Basic trigonomic calculations use the slant-range offset to calculate a 'fish' (tow-vehicle) navigation. An assumption in these calculations is that the tow-vehicle is traveling directly behind the vessel; movement to port or starboard is not accounted for within 'fish' navigation. Thus, the horizontal accuarcy of the sidescan-sonar tow-vehicle is +/- 15 meters. The horizontal positioning of the seismic systesm did not account for source and receiver offsets and offset the GPS antennae and the boomer source and streamer. It is estimated that these offsets could lead to inaccuracies of about 30 m. Interpretive products are based on the evaluation of sidescan-sonar, seismic-reflection, and sample data. Therefore, the horizontal accuracies of these systems will carry through to the interpretive products. As such, the horizontal accuracy of these data is assumed to be within +/- 30 meters. Lineage: Process_Step: Process_Description: These data are interpreted and based on acquired high-resolution seismic-reflection, sidescan-sonar, surficial sediment core and grab sample data. These various data types were placed within a Geographic Information System (ESRI ArcView 3.2) within which the interpretations were made. The final interpretations are stored as a polygon ArcView 3.2 shapefile. Process_Date: 2000 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jane F.
