Why was the data set created?

No purpose is given.

How was the data set created?

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

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?

   For usSEABED, the digital data and scanned report were downloaded via the web, visually compared to source and corrected. Where appropriate, data were tested for completeness using MS Excel.

2. How accurate are the geographic locations?

   Navigational techniques not known.

3. How accurate are the heights or depths?

   Water depth determination technique not noted in report.

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

   All available textural and statistical data are included in usSEABED. Additional compositional information and geophysical data were not digitized and are not included in usSEABED.

5. How consistent are the relationships among the observations, including topology?

   Data fall within normal ranges for the given parameters.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints: Cite U.S. Army Corps of Engineers as originators of the data
