  Data_Set_Credit: K.O. Emery and Jobst Hülsemann at the University of Southern California for the collection and analysis of data.  For inclusion into usSEABED: Digitization: Jane Reid (USGS); Formatting corrections: Jane Reid (USGS) and Chris Jenkins (University of Colorado).

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: 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.
  Logical_Consistency_Report: Data fall within normal ranges for analytical results.
  Completeness_Report: For usSEABED, appendix A was completely digitized.  Some information from the report text is also included in usSEABED.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Navigation by radar range and bearing.  Accuracy not noted in report; fixes were about 1.5 km apart at 9 to 10 knots taken every 5 minutes.  Positions given to minutes, seconds.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report: Depths by Precision Depth Recorder attached to an Edo echo sounder; depths uncorrected for sound velocity and are probably about 1.2 percent too shallow.
  Lineage:
    Process_Step:
      Process_Description: Textural analyses by standard pipette procedures for fines (<0.062 mm) and settling tube for coarse fraction (>0.062 mm.  Dried and weighed sediment samples were treated with sulfuric acid, heated, and the evolved carbon dioxide was measured volumetrically.  From these volumes, the percentages of calcium carbonate were computed on the assumption that all of the carbonate was combined with calcium...Calcium carbonate grains coarse enough to be identified as to source organisms consist dominantly of shell fragments in the coarse sediments and foraminiferal tests in the fine sediments.
