These data are part of the Brine Disposal Program funded by NOAA in the US Gulf of
Mexico, compiled by NOAA/CEAS and partially conducted by R. W. Hann of Texas A and
M University. Grain size analyses conducted on 230 grabs by Texas A and M University
were added to the historic NGDC Seafloor Sediment Grain Size Database from multiple
cruises of the Lady Gloria conducted during October of 1982. 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. Additional data submitted
for the Brine Disposal Program by Science Applications, Inc. (SAI) and collected during
multiple cruises of the Texas Star in September of 1977, the Dixie Isle in March of
198, and the Gus III from October 1978-May of 1979 were not added to the database
due to errors. |
