Title: SEDDATA database

Geospatial_Data_Presentation_Form: Digital

Other_Citation_Details:

Data collected by the University of Southern California (USC) under public funding provided by Donn Gorsline, 2001. Some data may overlap other USC publications held within usSEABED.

Description:

Abstract: No formal abstract is given.

Purpose: To compile USC's sediment data

Supplemental_Information:

Data were collected at least as early as 1958. Data digitized by the USGS for inclusion into usSEABED (<http://walrus.wr.usgs.gov/usseabed>)

Data_Set_Credit:

Students of USC for collecting and analyzing the data, agencies of local, state, and federal government for supplied funding for the data collection and analyses. Donn Gorsline (USC) compiled and supervised much of the data collection. For usSEABED, formatting and formatting corrections: Jane Reid (USGS) and Chris Jenkins (University of Colorado).

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

No estimate made for the accuracy of the data in the original report. Data digitized by the USGS and partners were visually compared to the source data, and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.

Logical_Consistency_Report: Data fall within normal ranges for analytical results.

Completeness_Report: Data completely included in usSEABED

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigational accuracy depends on techniques used and are not included in the SEDDATA database. More precise positions of some samples were located on the NGDC website (www.ngdc.noaa.gov); these positions were modified during the inclusion into usSEABED. Locations given at least to tenths of minutes.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Depth determination techniques not noted in the database. Locations given to nearest meters.
