BLM/OCS Ecological Investigations of Petroleum Production Platforms in the Central Gulf of Mexico

browse graphicsample locations in study area
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.
