This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.0001. Longitudes are given to the nearest 0.0001. Latitude and longitude values are specified in Decimal degrees.

" The objectives of this study include 1) determination of the textural and depositional characteristics of the recent marine sediments, 2) establishment of the distribution of the foraminifera, and 3) relating the distribution of the foraminifera to environmental factors."

Data sources produced in this process:
No estimate made for the original data. For inclusion into usSEABED, locations and statistical data were digitized by hand (typed in), visually compared to source and corrected as needed. Where appropriate, data were tested for completeness using MS Excel.
Locations determined by sextant and radar positioning, plotted on USC&GS chartsand by using ArcGIS 8.3 (2004) by georeferencing figure 2 to digital coastline.
Water depths determined by echo sounders or sounding lines.
No estimate made for the original data. For inclusion into usSEABED, collecting date and depth at MLLW were digitized from Appendix A. Appendix B (Physical data of the sediments) was completely digitized. Appendices C (Percent of living population and live diversity data) D (Percent of total population and totoal species diversity data), and E (Foraminiferal population data) were not digitized.
Data fall within normal ranges for given parameters.
Are there legal restrictions on access or use of the data?
