The program, Deep Gulf of Mexico Benthos or DGoMB, is studying the northern Gulf of Mexico (GOM) continental slope from water depths of 300 meters on the upper continental slope out to greater than 3,000 meters water depth seaward of the base of the Sigsbee and Florida Escarpments. The study is focused on areas that are the most likely targets of future resource exploration and exploitation. However, to develop a Gulf-wide perspective of deep-sea communities, sampling in areas beyond those thought to be potential areas for exploration has been included in the study design. A major enhancement in the program is the extension of the transects onto the abyssal plain of the central Gulf of Mexico through collaborative studies with Mexican scientists. This additional work effort will allow assessment of benthic communities structure and function throughout the basin by sampling the deepest habitats in the region. The program is designed to gain a better ability to predict variations in the structure and function of animal assemblages in relation to water depth, geographic location, time and overlying water mass. Biological studies are integrated with measurements of physical and chemical hydrographic parameters, sediment geochemical properties and geological characteristics that are known to influence benthic community distributions and dynamics. Eight (8) hypotheses are being tested on the basis of measures of benthic community structure. It is hypothesized that community structure varies as a function of: 1) water depth, 2) geographic location (east vs. west), 3) association with canyons, 4) association with mid-slope basins, 5) sea surface primary productivity, 6) proximity to hydrocarbon seeps, 7) time (seasonal and interannual scales), and 8) association with the base of escarpments.

Based on the copies of the field collection forms, the status of the samples collected during the particular field effort were updated by logging the appropriate information into the sample/data tracking system. Before a data file is incorporated as valid data into the program database, it is subjected to a data screening analysis--a quality control procedure designed to minimize errors. Original data sheets or laboratory reports were compared to verification listings, reviewing the latter for accuracy and completeness. This screening analysis includes range checking and thematic scanning of data to detect potential outliers and calculation of a statistical summary, which includes minimum, maximum, and mean values; numbers of valid observations, and total number of observations in the data file. This information and tabular listings of the data file are sent to the appropriate Principal Investigator for inspection. The Principal Investigator reviews the printouts and statistics for errors. Any errors in the data file are corrected, and new printouts are generated and sent to the Principal Investigator. After the Principal Investigator certifies in writing that the data file is valid, the data file is incorporated into the program database.
