Two sets of CTD data were taken during the 2012 surveys of the Louisiana continental shelf—Transect C off Terrebonne Bay and Transect F off Atchafalaya Bay and the 2012 Shelfwide Hypoxia cruise. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, Winkler results, and station information data were also acquired.

Physical and chemical oceanographic observational data collected by bottle and CTD in the Gulf of Mexico from R/V Gyre and R/V Pelican, April 2004 - July 2009. Data were submitted from the project Mechanisms Controlling Hypoxia on the Louisiana Shelf. This data are part of a comprehensive and multidisciplinary study of the Texas-Louisiana Shelf that included interdisciplinary process cruises and shelf-wide surveys to complement, and provide rates and other parameters necessary for the initiation, control, and skill assessment of a realistic coupled three-dimensional hydrodyamic-biological-geochemical-sediment numerical modeling and statistical (multivariate) modeling elements.

CTD data were taken during surveys of the Louisiana continental shelf during yearly Shelfwide Hypoxia cruises. Hydrographic data were obtained using CTD. Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, and station information data were also acquired.

Two sets of CTD data were taken during the 2011 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.

This dataset contains water temperature, salinity, oxygen, and other parameters collected by CTD from research vessel Pelican in the Gulf of Mexico from 2020-09-25 to 2020-10-04. Hydrographic data were collected on a mid-experiment telemetry cruise from an array of moored instrumentation. These data were collected to calibrate the travel time measurements of the moored current- and pressure-recording inverted echo sounders. The data are in NetCDF format.

This dataset contains water temperature, salinity, oxygen, and other parameters collected by CTD from research vessel Pelican in Gulf of Mexico from 2019-06-14 to 2019-10-03. Hydrographic data were collected on the deployment cruise of an array of moored instrumentation and on a mid-experiment telemetry cruise. These data were collected to calibrate the travel time measurements of the moored current- and pressure-recording inverted echo sounders. Some instrument sites were visited more than once on each cruise. The data are in NetCDF format.

Sampling of in situ seawater, macroalgae, macrocrustaceans and associated fauna (cruise GoMRI-II, October 17-20 2013, stns 1-18, data available for all) aboard the R/V Pelican cruise id PE14-10b was targeted to repeat sampling of previously studied hard banks and adjacent deep waters west of the mouth of the Mississippi River and extending east to offshore Alabama, an area encompassing roughly 27°58'N to 29°26'N and 87°34'W to 91°01'W. Submitted metadata are ADCP, CTD, Marks and Cruise Track Data.

The accession contains several data sets collected during cruise P921 of the R/V Pelican as part of the Mississippi River Plume Hydrographic Study. Data submitted to NODC in delimited ASCII. One data set contains CTD (Depth, Conductivity, and Temperature data); file(s) also include salinity, dissolved oxygen, backscatter, transmissometer (turbidity), and pressure. This data does not include header information and was not able to be processed in a standard NODC format. Another data set contains Oxygen and Hypoxia data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Third data set contains ADCP (Acoustic Doppler Current Profiler) data collected as part of LATEX (Louisiana-Texas) project. Data was exported for NODC in delimited ASCII. Fourth data set contains Chlorophyll (CHL), Phaeophytin, Salinity, Temperature, and Secchi Disc data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Fifth data set contains Zooplankton data. All the data in this accession is considered INTERIM data; the originator's documentation and file record do not fully correlate with the actual number of files and data types submitted. Final data report was expected to be available by 08/31/93.

R/V Pelican: PE14-20 Hydrographic (CTD) Data, Gulf of Mexico (GC600 and AT357), GC600 and AT357. Five conductivity, temperature and depth (CTD) casts made from R/V Pelican in the northern Gulf of Mexico in lease blocs GC600 and AT357 in conjunction with and support of ongoing mooring and deep sea lander experiments.

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.
