BLM/OCS South Texas Outer Continental Shelf (STOCS) Project Sediment Data
browse graphicThe South Texas Outer Continental Shelf Project (STOCS) conducted by the University of Texas and the USGS with funding from BLM/NOAA. The USGS produced geochemical analyses of sediment and suspended sediment, clay mineralogy, and physical properties of sediment for 264 samples collected from October 26, 1974 to December 21, 1974. Additional grain size analyses are not included in the Seafloor sediment digital grain size database due to numerous errors. The University of Texas produced grain size analyses in the historic 073 format for 1647 sea floor samples collected from February 8, 1976 to October 18, 1977. 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 digital grain size database.
