This data collection includes profile data containing temperature, salinity and associated variables collected in support of this research program to gain better knowledge of the benthic communities of the deep Gulf of Mexico, 1999 - 2002. Funding provided by USDI/MMS Contract No. 1435-01-99-CT-30991 for the US Department of the Interior, Minerals Management Service-sponsored program entitled The Deepwater Program: Northern Gulf of Mexico Continental Slope Habitat and Benthic Ecology. Principal investigators: Dr. Gilbert T. Rowe, Dr. Mahlon C. Kennicutt, Dr. Bob J. Presley, Dr. Gary A. Wolff, Dr. Joan Bernhard, et. al.

This dataset includes measurements of the following parameters: Profile Currents, currents, Temperature (water), salinity, pressure, profile CTD, PALFOS profile CTD and currents, PIES (estimates of vertical profiles of temperature, salinity, density and referenced geostrophic velocities), remote sensing (SST, SSH). The data were collected on the following cruises: LH845-03, LH846-03, LH847-03, PE04-10, PE04-12, PE04-17, TM080-04, PE04-34, PE04-35, TM084-04. During this study fixed position moorings supporting acoustic doppler current profilers (ADCPs), fixed level current meters, and a variety of sensors to measure conductivity, temperature and pressure. Additionally, inverted echo sounders with pressure (PIES) were placed on the bottom at specific locations over the study area. This placement was coordinated with both current measurements and the coordinated remote sensing component of this study - in particular sea surface height. The final observations were provided by both profiling (PALFOS) and fixed level (RAFOS) drifters placed in the study area but allowed to drift and provide lagrangian information as well as C/T profiles where PALFOS floats rose to the surface every ten days. The primary objectives of the study were to develop an improved understanding of the conditions and processes that resulted in the documented circulation patterns in the study area and how these related to forcing mechanisms important to the overall upper and lower-layer Gulf circulation and transport. Results showed that in the relatively anomalous study interval, upper layer circulation patterns dominated Loop Current related eddies (cyclonic and anticyclonic). Relatively weak correlation could be defined between upper and lower layer circulation patterns. Lower-layer currents were apparently strongly affected by the presence of the Sigsbee Escarpment. Many measured current patterns could be related to topographic Rossby waves of various periods that varied with position relative to the Loop Current and bottom topography. The Minerals Management Service (MMS) awarded a contract to Science Applications International Corporation (SAIC) to conduct a four-year study titled: Exploratory Study of Deepwater Currents in the Gulf of Mexico (often referred to as simply the Exploratory Study).

Original title provided by data contributor in the included FGDC description for these data is "CTD Cast Data ".

Current direction, bathythermograph (xbt), CTD, and other data were collected using moored current meter casts and other instruments in the Gulf of Mexico from April 4, 1987 to November 2, 1988. Data were submitted by Science Applications, INC - Raleigh NC as part of the Gulf of Mexico Physical Oceanography (GMPO) project. Data has been processed by NODC to the NODC standard F015- Current Meter Data, F022- CTD High Resolution, C100- Ocean Station Data, and C116/118- Bathythermograph XBT formats. The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments. The Oceanographic Station Data (C100) format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters are temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t), sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels. The C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature

Chemical, current meter, and other data were collected using current meter, bottle, XBT, and CTD casts in the Gulf of Mexico from November 16, 1997 to August 8, 2000. Data were submitted by Texas A&M University as part of the Northeastern Gulf of Mexico Physical Oceanographic Program: Chemical Oceanography and Hydrography Study (NEGOM) project. There were nine cruises, all aboard R/V Gyre. The same 11 cross-shelf lines were occupied during each cruise. On each cruise, profiles of temperature, salinity, dissolved oxygen, fluorescence, backscatterance, PAR, and percent transmission were made with a Seabird CTD. Water samples were taken and analyzed for salinity, dissolved oxygen, nutrients, pigments, particulate material, particulate organic carbon and particulate organic nitrogen. Many XBT probes were released. An underway flow-through system measured near-surface temperature, salinity, and fluorescence. Acoustic Doppler current profilers measured vertical profiles of currents while underway.
