Full Citation Examples
The overall usSEABED database holds data for the entire U.S. Exclusive Economic Zone and is an ongoing task of the Marine Aggregates Resources and Processes and National Benthic Habitats Studies (Pacific) projects, USGS Coastal and Marine Geology teams in Santa Cruz, CA, Woods Hole, MA, and St. Petersburg, FL, and the University of Colorado.
This data layer is a point coverage of known sediment samplings, inspections and probings from the usSEABED data collection and integrated using the software system dbSEABED. This data layer represents the extracted (EXT) output of the dbSEABED mining software. It contains data items which were simply extracted from the data resources through data mining. The EXT data is usually based on instrumental analyses (probe or laboratory) but may apply to just a subsample of the sediment (eg. no large shells).
This data is displayed using the Modified Shepard code pertaining to the grain size classification.

| Abstract: |
The overall usSEABED database holds data for the entire U.S. Exclusive Economic Zone and is an ongoing task of the Marine Aggregates Resources and Processes and National Benthic Habitats Studies (Pacific) projects, USGS Coastal and Marine Geology teams in Santa Cruz, CA, Woods Hole, MA, and St. Petersburg, FL, and the University of Colorado. This data layer is a point coverage of known sediment samplings, inspections and probings from the usSEABED data collection and integrated using the software system dbSEABED. This data layer represents the extracted (EXT) output of the dbSEABED mining software. It contains data items which were simply extracted from the data resources through data mining. The EXT data is usually based on instrumental analyses (probe or laboratory) but may apply to just a subsample of the sediment (eg. no large shells). This data is displayed using the Modified Shepard code pertaining to the grain size classification. |
| Purpose: |
To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act. |

|---|---|
| Description: |
Partial upload of Positional Accuracy fields only. |
Data Quality
| Accuracy: |
Accuracy of each attribute is dependent on the accuracy of the lineage data. |
|---|---|
| Horizontal Positional Accuracy: |
Maximum scale of intended use is 1:80,000. |
| Completeness Report: |
Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness. |
| Conceptual Consistency: |
These data are believed to be logically consistent. Geometry is topologically clean. |

Process Steps
Process Step 1
| Description: |
Acquire source data, create new feature class and set-up schema, load data from source data, verify attributes were carried over correctly and fix if needed, deleted all fields that contained no data for all the attributes (class membership, rock membership, weed membership, and critical shear stress), |
