More information on this study is available through NGDC (<http://www.ngdc.noaa.gov>) as MGG ID 23085001; however, the interval data (phi-sized bins) from NGDC are mixed up and should not be used.

2. What geographic area does the data set cover?

   West_Bounding_Coordinate: -93.50967

   East_Bounding_Coordinate: -93.31133

   North_Bounding_Coordinate: 30.05883

   South_Bounding_Coordinate: 29.66033

3. What does it look like?

4. Does the data set describe conditions during a particular time period?

   Beginning_Date: 02-Oct-1981

   Ending_Date: 16-Oct-1982

   Currentness_Reference: Publication date

5. What is the general form of this data set?

   Geospatial_Data_Presentation_Form: Digital

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Point (218)

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.00001. Longitudes are given to the nearest 0.00001. Latitude and longitude values are specified in Decimal degrees.

7. How does the data set describe geographic features?

   Entity_and_Attribute_Overview:

   Data provided include sampler, percentages of gravel,sand, silt, and clay, and granulometric analyses in one-phi increments.

   Entity_and_Attribute_Detail_Citation: Chuck Holmes' data compilation.

Who produced the data set?

1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
   • Texas A and M University

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   No assessment of data accuracy can be given. Where appropriate, data were tested for completeness using MS Excel.

2. How accurate are the geographic locations?

   Navigational techniques not recorded in report; latitudes and longitudes given in decimal degrees; five significant figures.

3. How accurate are the heights or depths?

   Water depth determination technique not noted in report. Water depths in meters.

4. Where are the gaps in the data? What is missing?

   All available textural, statistical, and compositional information are included in usSEABED. The Holmes compilation may also include metal and organic contaminant values requested by or performed by the EPA, USGS, USACE, and others for these samples that are not included in usSEABED.
