This dataset contains water temperature, salinity, and other physical, chemical, and biological parameters taken by CTD and water quality sonde in the Gulf of Mexico from 2015-06-23 to 2015-12-09. Two sets of CTD data were taken during the 2015 Shelf wide Hypoxia cruise off the Louisiana continental shelf. Hydrographic data were obtained with the Louisiana Universities Marine Consortium (LUMCON) SeaBird 911+ CTD system and a multi parameter water quality sonde (YSI 6820). Nutrient, pigment, suspended sediment, surface salinity, Secchi depth, Winkler results, and station information data were also acquired. Additionally, profiles were taken throughout the year at station C6C as well at several sites in August during a box coring cruise. Original data in Excel format (XLSX) were converted to ASCII (CSV) format.

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.

This dataset includes Surface underway, chemical, discrete sample, meteorological, physical and profile data collected from PELICAN in the Coastal Waters of Louisiana, Coastal Waters of Texas and Gulf of Mexico from 2013-09-09 to 2013-09-22. These data include BAROMETRIC PRESSURE, CONDUCTIVITY, DISSOLVED INORGANIC CARBON (DIC), Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE and pH. The instruments used to collect these data include Alkalinity titrator, CTD, Carbon dioxide (CO2) gas analyzer, Non-dispersive infrared (NDIR) dissolved inorganic carbon (DIC) analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, bottle and pH sensors. These data were collected by Antonio Mannino of US NASA; Goddard Space Flight Center (GSFC) and Christopher W. Hunt and Joseph E. Salisbury of University of New Hampshire (UNH) as part of the Coastal_GOMEX2013_BOT and Coastal_GOMEX2013_UW dataset. CDIAC associated the following cruise ID(s) with this dataset: 32PE20130909 and GOMEX2013 The Global Coastal Carbon Data Project data includes the bottle (discrete) and surface (underway) carbon-related measurements from coastal research cruises, the data from time series cruises and coastal moorings. The coastal regions data are very important for the understanding of carbon cycle on the continental margins.

Two sets of CTD data were taken during the 2014 Shelfwide Hypoxia cruise off 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, Winkler results, and station information data were also acquired.

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.

Hydrographic and chemical data were collected for a week in late July between 1994-1997 in order to survey the coastal hypoxia on Louisiana continental shelf. Nutrient, pigment, suspended sediment and station information data were also acquired. Data files provided in Microsoft Access format, from which NCEI provides a redundant copy in text format.

Chemical, zooplankton, and phytoplankton data were collected using bottle, CTD, fluorometer, oxygen meter, GPS, plankton trap, and sediment sampler from NOAA Ship MALCOLM BALDRIGE and NOAA Ship RESEARCHER. Data were collected from the Mississippi River and Gulf of Mexico from July 15, 1985 to May 12, 1993. Data were submitted by Dr. Nancy Rabalais from the Louisiana Universities Marine Consortium as part of the Nutrient Enhanced Coastal Ocean Productivity (NECOP) project.

Measurements from the Pelican research vessel made off the southern coast of Louisiana in the Gulf of Mexico from 2006.

Data included in this accession consists of volume discharges from the Mississippi and Atchafalaya rivers collected by Louisiana State University from September 1985 to December 1987 as part of the MMS/OCS development and potential coastal habitat alteration. The sampling area was coastal Louisiana. Parameters reported are salinity, temperature and water levels. This work was funded under MMS contract number 14-12-0001-30252. The documentation includes the data format and site identification.
