  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?

    Statistical data was digitized by hand (typed in) at NGDC. For usSEABED, digital data and the scanned reported were downloaded via the web, visually compared to source and corrected. Additional data may have been included from the scanned report, also available online. 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 in degrees and minutes.

  3. How accurate are the heights or depths?

    Water depth determination technique not noted in report. Water depths given, subsample depths in centimeters from top of core.

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

    All data available online and in scanned report are included.

  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?

Access_Constraints: None
Use_Constraints:
Cite U.S. Naval Oceanographic Office and NGDC as originators of the data

  2. What's the catalog number I need to order this data set?

    MGGID 09005007

  3. What legal disclaimers am I supposed to read?

    Although this dataset has been used by the USGS, no warranty, expressed or implied, is made by the USGS as to the accuracy of the data. Users of the data should be aware of limitations of the data due to possible imprecision due to navigational inaccuracies, limitations of the statistical data, and digitizing errors.
