Two sets of CTD data were taken during the 2010 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, and station information data were also acquired. The physical, biological and chemical data collected are part of a long-term coastal Louisiana dataset. The goal is to understand physical and biological processes that contribute to the causes of hypoxia and use the data to support environmental models for use by resource managers.

The Conductivity, Temperature and Depth (CTD); and bathythermograph (XBT) data were collected as part of Distribution/Abundance of Marine Mammals in Gulf of Mexico (GULFCET I) funded by grant no MMS 14-35-0001-30619. The data was collected over two year period spanning from April 15, 1992 to December 12, 1993. Data from 239 casts of CTD and 566 XBT drops was submitted via internet by Dr. Giulietta Fargion of Texas A&M University, Galveston, TX.

The Conductivity, Temperature and Depth (CTD) and Water Depth and Temperature Bathythermograph (XBT) data were collected in Gulf of Mexico as part of Texas Institutions Gulf Ecosystem Research (TIGER) project funded by grant no MMS # 14-35-0001-30501. Data was collected from Ship GYRE cruises 92G09, 92G10 and 92G13. The data was collected over a period spanning from September 26, 1992 to October 31, 1992. Data was submitted in two diskettes by Dr. Douglas C. Biggs, Texas A&M University, College Station, TX. The originator's data containing 32 CTD observations; 52 stations and 12,860 records has been processed. CTD data is available in F022-CTD-Hi Resolution file format of NODC. The originator's bathythermograph (XBT) data has been converted and are now available on line in C116 (XBT) file format of NODC. 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 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 values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.

The Conductivity, Temperature and Depth (CTD) and Bathythermograph (XBT) data were collected as part of Texas Institutions Gulf Ecosystem Research (TIGER) program. One week of data was collected from Gulf of Mexico using Ship GYRE. The data was collected over a period spanning from March 2, 1991 to March 9, 1991. Data was collected as part of a study supported by grant MMS # 14-35-0001-30501 to Dr. Douglas C. Biggs and was submitted by Dr. Edward Webb of Texas A&M University, College Station, TX. Data has been processed and is available in F022-CTD-Hi Resolution and C116-Bathythermograph-XBT file format of NODC.

Physical, chemical, and other data were collected using trawl, SeaWifs and other instruments from the GYRE from the Gulf of Mexico. Data were collected from August 1, 1999 to August 1, 2002. Data were submitted by the Texas A&M University as part of the Deepwater project.

The Conductivity, Temperature and Depth (CTD) and bathythermograph (XBT) data were collected in Gulf of Mexico as part of Texas Institutions Gulf Ecosystem Research (TIGER) and LATEX project funded by grant no MMS # 14-35-0001-30501. Data was collected from Ship GYRE. The data was collected over a period spanning from June 2, 1993 and June 24, 1993. Data was submitted by Mark Garner, Texas A&M University, College Station, TX. Data has been processed and is available in F022-CTD-Hi Resolution and C116 Bathythermograph file format of NODC. Objective of LATEX A was to observe currents and waves, water properties (such as temperature, salinity and nutrients), and air-sea interaction over the Texas- Louisiana shelf, with the aim of providing data adequate to describe and better understand the circulation and transport of water, nutrients and other properties over that shelf.

This dataset contains oceanographic and surface meteorological data in netCDF formatted files, which follow the Climate and Forecast metadata convention (CF) and the Attribute Convention for Data Discovery (ACDD). Sanibel-Captiva Conservation Foundation River, Estuary and Coastal Observing Network, collected the data from their in-situ Gulf of Mexico station in the Coastal Waters of Florida, Gulf of Mexico, and North Atlantic Ocean. Southeast Coastal Ocean Observing Regional Association (SECOORA), which assembles data from Sanibel-Captiva Conservation Foundation River, Estuary and Coastal Observing Network, and other sub-regional coastal and ocean observing systems of the Southeast United States, submitted the data to NCEI as part of the Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. NCEI updates this dataset when new files are available.

Wetland Assessment Data was collected from Coastal waters of Gulf of Mexico by Louisiana State and the Louisiana Geological Service under MMS Cooperative Agreement No.14-12-0001-30410-Mitigation of Wetland Impacts due to OCS Oil and Gas Activities. Data include suspended solids, soils, currents, temperature, salinity, ammonia, nitrate, nitrite, phosphate, Secchi depth, sedimentation, chlorinity, tides, biology, invertebrates, marshes, leaf and stem biomass and chemistry, and heavy metals. Data was collected between January 1, 1988 and December 31, 1989. Data was submitted on tape containing files AO1373 and 18770 that have been copied onto the current NODC storage media.
