Why was the data set created?

Data cited in USGS OFR 00-167; no formal purpose is given for the Smith et al., 1980, report.

How was the data set created?

1. From what previous works were the data drawn?

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

   Date: Unknown (process 1 of 1)

   Unknown

   Data sources produced in this process:

   • USACE_Smith_1980

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 estimate made for original data. For inclusion in OFR 00-167, gravel, sand, silt/clay fractions were reported. For usSEABED, data were culled from USGS OFR 00-167 and formatted into usSEABED structure under the original source. Where appropriate, data were tested for completeness using MS Excel.

2. How accurate are the geographic locations?

   No navigational information is given in the original report. Positions given in decimal degrees (four significant figures).

3. How accurate are the heights or depths?

   Water depths determination method not recorded in report; Water depths given to nearest centimeter

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

   No estimate made for original data. For usSEABED, all data in OFR 00-167 provided by this report were included.

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

   Data mostly fall within normal ranges for the given parameters; several samples had sand percentages > 100, and/or total GSM <> 100 %.

How can someone get a copy of the data set?

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

Access_Constraints: Report may be available at some libraries.
