Integrated using the software system dbSEABED. Purpose: These data are intended to assist research, education, policy development commerce, and the general public. The data can be used with geographic information systems (GIS) and relational database (RDB) software to display geologic, environmental and oceanographic information.

Logical_Consistency_Report: Point features present. Each data point has a unique identification (SiteName, Dataset, Date, Latitude, Longitude, Water Depth, Subbottom Depth, Described Phase) with corresponding attributes attached. Completeness_Report: The data represent measured, described and calculated field- and lab-derived values of textural, compositional, geological and geophysical parameters. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positional accuracy is dependent on source accuracy and may vary from 0.005km (differential GPS) from more recent source surveys to 1 to 2 km or more based on radar, Loran, or dead reckoning in older surveys. Users should use their own criteria to evaluate locations of these data. The precision of the output positions is 0.00001 degrees (approx 1m).
