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 0.00001. Longitudes are given to the nearest 0.00001. Latitude and longitude values are specified in Decimal degrees.
Alpha numeric number based on cruise and core information

"The principle [sic] objective of the cruise was to collect a suite of piston cores across the California Current with records of at least the last 150 ka so that the temporal history of the current can be investigated. A second objective was to locate and core pelagic-carbonate sediments above the presumed 3000-m depth of the calcite lysocline on seamounts off the California margin to capture the uncontaminated (by terrestrial components)oceanic signal."
Person who carried out this activity:
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.
Navigation probably mostly by GPS.
Water depth determination by 3.5 kHz profiling systems. Subsample depths given as nearest centimeter.
No estimate made for original data. For inclusion into usSEABED, all descriptive data in the report were included.
Data fall within normal ranges for the given parameters.
Are there legal restrictions on access or use of the data?
- None. Paper copy of report is available through the USGS, and is also available online.
- Use_Constraints: Cite the U.S. Geological Survey as the originators of the data.
