Why was the data set created?

Not 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?

   Date: Unknown (process 1 of 1)

   None information available.

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 the accuracy of the data in the original report. Data digitized by the USGS and partners were visually compared to the source data, and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.

2. How accurate are the geographic locations?

   No navigational information is given on the map; locations given to minute-tenths

3. How accurate are the heights or depths?

   No water-depth determination information given on the map; water depths given to nearest meter (uncorrected).

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

   No assessment made for original data. For inclusion into usSEABED, all data on sheet one were included; additional data from sheets 2 and 3 will be added at a later date..

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

   No assessment for original data.

How can someone get a copy of the data set?
