usSEABED: Coastal & Marine Geology Program


Components and features mined within usSEABED

Word-based data provides component information (sediment content) and features information (structural, soft biota, or other non-textural information). Examples of mined data with numeric values are given below, with more complete information given in the usSEABED publications. Component fields note presence only, not absence.

Appropriately grouped components are facies. [back]
