Dr. L.J. Doyle produced grain size analyses in the historic 073 format for 2,168 sea floor samples collected on multiple cruises (MAFLA cruises 2, 10, 11, 29, 39, 14, 21, and MAFLA DM1 and DM2) conducted in the Gulf of Mexico from May 16, 1974 through February 20, 1978. 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.
