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 (206)

   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.

Why was the data set created?

From Rick Fletcher: "Attached is a zip file with two themes. 2000Reseachgrabs cruise are historical lie stations that we resample. It has been processed so you can see what we are producing as a product. We used the Udden-Wentworth method of classifying grain size. The second is Hab_grab which is all our grab positions, however you will see they are generally in groups of 4 & where that is the case only one is being processed for grain size the others are for biological analysis."

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)

   No 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 information on navigation is noted.

3. How accurate are the heights or depths?

   Water depths not given.

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

   No assessment is made

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

   Data fall within expected boundaries

How can someone get a copy of the data set?
