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 recorded in report; latitudes and longitudes given to degrees, decimal minutes.

3. How accurate are the heights or depths?

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

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?
