For usSEABED, digital data and the scanned report were downloaded via the web, visually compared to source and corrected. Additional data may have been included from the scanned report, also available online. Where appropriate, data were tested for completeness using MS Excel. Logical_Consistency_Report: Data fall within normal ranges for the given parameters. Completeness_Report: All available textural, statistical, and compositional information are included in usSEABED. The Holmes (USGS) compilation may also include metal and organic contaminant values requested by or performed by the EPA, USGS, USACE, and others for these samples that are not included in usSEABED. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigational techniques not recorded in report; latitudes and longitudes given in decimal degrees; three significant figures. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Water depth determination technique not noted in report. Water depths given in meters.
