abstract: 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.

statement: These data were contributed by the originator to NOAA's former National Oceanographic Data Center (NODC) and are part of a larger compilation archived as oceanographic data by NCEI. The following brine disposal data sets with grain size information compiled by SAIC were submitted to NGDC in December of 1979: MGG03495001 (Gus III 10/3/78-11/10/78, Brine 1/SEDDY2; 1/23/79-1/28/79, Brine 2/SEDDY3; 4/25/79-5/2/79, Brine 3/SEDDY4); MGG03505001 (Texas Star 9/17/77, Brine 5); MGG03515001 (Dixie Isle 3/31/78, Brine 6); Brine 4 (returned for error correction/never resubmitted). Due to extensive errors in weight percentage totals, none of the preceding data files were added to the NGDC Seafloor Sediment Grain Size database, but copies of these data, with the exception of Brine 4, are in the archive. In June of 1981 data set MGG03115001 was received from SAI Oakridge through Francis Mitchel of NODC (42 files from 9/20/1977-10/19/1978 cruises of SW Researcher) but returned to NODC for NOAA/CEAS correction in May 1982 - the data were never resubmitted. In December of 1983, a final Brine Disposal data set MGG23085001 (13 cruises of the Lady Gloria) was received from Texas A and M which had no significant errors and was added to the digital grain size database.
processStep: (LI_ProcessStep)
description: From 1975 through the 1980s, most sediment data collected as part of offshore environmental baseline and/or habitat studies were part of a suite of measurements sent to NODC or NODC liasons. NODC data managers, primarily Francis Mitchel, then sent the sediment-related data (e.g., physical properties, composition, geochemstry, mineralogy) to the former NGDC as the authoritative archive and distribution point for sediment data. Many sediment analyses and descriptions, however, were maintained by NODC as benthic habitat data, and some additional sediment data were duplicated between the NODC and NGDC archives.
