Why was the data set created?

" This report briefly summarizes the geological and biological data taken off northern California before and duirng the Coastal Ocean Dynamics Experiment (CODE) by the principal investigators of the bottom stress/ bottom boundary layer of CODE (D. Cacchione, D. Drake, USGS; and W. Grant, A. Williams, WHOI) and other cooperating investigators of the U.S. Geological Survey."

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)

   "The sediment samples were treated with hydrogen peroxide solution to remove organic materials, and then sieved to separate the sand and finer components. Size analyses for the sand and the silt/clay faction were carried out with theUSGS rapid sediment analyzer (RSA) and hydrophotometer, respectively."

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 report. For usSEABED, data were digitized (typed in), compared to original and corrected as needed. Where appropriate, data were tested for completeness using MS Excel.

2. How accurate are the geographic locations?

   Navigation generally by Loran C (Range range); given to minutes-hundredths.

3. How accurate are the heights or depths?

   Depth determinations by 12 kHz or 3.5 kHz echosounders, given to nearest meter.

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

   See report. For inclusion into usSEABED, all data in the report were included.

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

   Data fall within expected ranges for the attributes measured.

How can someone get a copy of the data set?

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