This dataset contains CTD data collected aboard R/V Endeavor cruises EN509 and EN510 (sequential legs) using a CTD-rosette system in the Gulf of Mexico from 2012-05-26 to 2012-07-04. The physical and chemical properties in the water column at the ECOGIG seep and other study sites were characterized The dataset also includes binned profiles and bottle files.

This dataset contains CTD, water quality and particle and zooplankton sample elemental (total C and N, C/N ratio) and isotopic (delta 13C, delta 15N) data collected during R/V Endeavor cruise EN496 in the northern Gulf of Mexico from 2011-07-03 to 2011-07-26. Particle and zooplankton samples were collected during cruise EN496 using a CTD-rosette and a MOCNESS. The objectives were to collect water column and benthic samples in the vicinity of the Mississippi River Plume, as well as, at/near active seeps. Elemental and isotopic data were collected at 18 stations, while CTD profiles were done at 51 locations. Elemental and isotopic data includes the delta 13C and 15N, total Nitrogen and Carbon and the C/N ratio. Hydrographic data was collected using a Sea-Bird SBE-9 and the data includes temperature, salinity, oxygen concentration, sound velocity, beam attenuation and transmission, sea level, Photosynthetically Active Radiation (PAR), fluorescence and surface irradiance.

This dataset contains conductivity, temperature, and depth data from R/V Bellows cruise BE-1322 of the offshore shelf of the Florida Panhandle Bight at the head of DeSoto Canyon from June 2nd to 4th, 2013. Water samples collected were analyzed by the Wetlands Research Laboratory at the University of West Florida for nutrient concentrations. Water samples were filtered in the lab and cell counts for phytoplankton species are reported. Phytoplankton were photographed using scanning electron microscopy and images are provided in this dataset.

CTD Data from the cruise BE-1415 on May 2014. The cruise will be sampling to document any residual hydrocarbons from the BP MC252 well eruption and provide time series hydrographic, water chemistry, sediment, and plankton data as a baseline and to document the physical and biological seasonal dynamics for the offshore shelf of the Florida Panhandle Bight at the head of DeSoto Canyon.

A Minerals Management Service (MMS) program entitled Survey of Deepwater Currents in the Eastern Gulf of Mexico, awarded to Evans-Hamilton, Inc. This data set includes physical oceanographic data from CTD and ADCP moorings deployed in the Eastern Gulf of Mexico from January 19, 2005 to January 28, 2006. The data are in ASCII forms subjected to quality control and quality assurance procedures.

Conductivity Temperature and Depth (CTD) measurements were collected aboard R/V Ocean Veritas 07 to determine physical oceanographic parameters of the water column, and in some cases used to help guide sample collection as part of the Deepwater Horizon oil spill sampling effort. Temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry data were collected onboard R/V Ocean Veritas 07. The final product is a series of NetCDF files containing every CTD cast that has been processed and quality checked.

Conductivity Temperature and Depth (CTD) measurements were collected aboard R/V Ocean Veritas 11 to determine physical oceanographic parameters of the water column, and in some cases used to help guide sample collection as part of the Deepwater Horizon oil spill sampling effort. Temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry data were collected onboard R/V Ocean Veritas 11. The final product is a series of NetCDF files containing every CTD cast that has been processed and quality checked.

Conductivity Temperature and Depth (CTD) measurements were collected aboard R/V Ocean Veritas 06 to determine physical oceanographic parameters of the water column, and in some cases used to help guide sample collection as part of the Deepwater Horizon oil spill sampling effort. Temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry data were collected onboard R/V Ocean Veritas 06. The final product is a series of NetCDF files containing every CTD cast that has been processed and quality checked.

Conductivity Temperature and Depth (CTD) measurements were collected aboard R/V Ocean Veritas 04 to determine physical oceanographic parameters of the water column, and in some cases used to help guide sample collection as part of the Deepwater Horizon oil spill sampling effort. Temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry data were collected onboard R/V Ocean Veritas 04. The final product is a series of NetCDF files containing every CTD cast that has been processed and quality checked.

This dataset contains depth - bottom, depth - observation, dissolved oxygen, fluorescence, salinity, sound velocity, transmissivity, water density, and water temperature from CTD collected aboard NOAA Ship Oregon II during cruise R2-16-01 in the the Gulf of Mexico from 2016-04-30 to 2016-05-30. These data were collected and submitted by Christopher Gledhill of US DOC; NOAA; NMFS; Southeast Fisheries Science Center; Pascagoula/Stennis, MS Laboratory.
