BLM/OCS Ecological Investigations of Petroleum Production Platforms in the Central Gulf of Mexico
Dataset Publication Date:
The Ecological Investigations of Petroleum Production Platforms in the Central Gulf of Mexico Project was conducted by Texas A and M University under contract to NOAA and the Bureau of Land Management under the BLM/OCS Outer Continental Shelf Program. Grain size analyses were produced for 1654 samples collected from May 22, 1978 through January 15, 1979 by the ships Sea Transporter and T-Kip IV in the central Gulf of Mexico. Analyses were contributed in the historic 073 format. Data include collecting institution, ship, cruise, sample id, latitude/longitude, date of collection, water depth, sampling device, method of analysis, sample weight, sampled interval, raw weight percentages of sediment, within a given phi range. Some samples also have percentages of total gravel, sand, silt, clay, and statistical measurements such as mean, median, skewness, kurtosis, and standard deviation of grain size. These data are part of the larger NGDC digital grain size database.

Data Quality Information
Scope (quality information applies to):
These data were contributed by the originator to NOAA's former National Oceanographic Data Center (NODC) and may be part of a larger compilation archived as oceanographic data by NCEI. A total of 10,340 records in the 073 grain size format were received, 3,065 (488 samples Sea Transporter I); 3,505 (561 samples T-Kip IV II-A); 1,537 (245 samples Sea Transporter II-C); 2,233 (360 samples Sea Transporter III).
