Description:

Abstract:

The USGS East-Coast Sediment Texture database contains location, description, and texture of samples taken by numerous marine sampling programs of the Coastal and Marine Geology Program. Most of the samples are from the Atlantic Continental Margin of the United States, but some are from as diverse locations as Lake Baikal, Russia, the Hawaiian Islands region, Puerto Rico, the Gulf of Mexico, and Lake Michigan. The database presently contains data for over 21,000 samples, which includes texture data for approximately 3800 samples taken or analyzed by the Atlantic Continental Margin Program, a joint U. S. Geological Survey/Woods Hole Oceanographic Institution project conducted from 1962 to 1970. The surficial sediment information provided in this data layer have been clipped from this source database. Data are limited to those samples processed by the USGS sediment laboratory at the Woods Hole Science Center and are from off the northeastern United States.

Purpose:

This ArcView shapefile contains the locations of marine sediment samples collected and analyzed by the U.S. Geological Survey, Woods Hole Science Center starting in 1980 thru 2002. Distribution of this dataset allows the user the ability to visualize the information in a Geographic Information system.

Supplemental_Information:

This dataset is a subset of the original data set released in USGS OFR00-358. The original dataset has been clipped to include only those samples falling within the Gulf of Maine GIS project bounds.

The Excel spreadsheet contains the available data on grain size for the bottom sediments produced by the USGS, Woods Hole Science Center. The basic structure of the file is a matrix where records are rows representing individual samples and the columns contain information on sample identification, navigation, classifications, analyzed parameters, and comments.

Process_Step:

Process_Description:

The Excel spreadsheet was edited to change the PHI field names. The negative PHI values -5 to -1 were changed from PHI-n to PHIMn. This is because ArcView does not allow the '-' in field names and the field names were automatically changed to 'PHI_n'. This resulted in duplicate PHI field names. Making the change before exporting the file eliminated the conversion error and fieldname problems.

The modified Excel spreadsheet file, usgsecstdb.xls, was exported as an ASCII text file with tab delimited fields.
