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 CTD vertical profiles of hydrographic and ecologically-relevant environmental data collected at and near specialized deep-sea habitats and throughout the water column along the U.S. Atlantic margin for Deep Search project in August-September 2018. These data were collected in order to provide environmental context for deep-sea coral, cold seep, and canyon habitats. Data are in excel spreadsheet format.

These datasets consist of profile data collected by CTD casts in the northern Gulf of Mexico that are collected as part of the annual summer groundfish survey supported by the Southeast Area Monitoring and Assessment Program (SEAMAP). SEAMAP is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States. Data are in Sea-Bird CNV format.

The 2014 PIRATA Northeast Extension Cruise EN-550 was designed to collect observations in the northeast Tropical Atlantic, to service the northeast extension of the PIRATA array, to collect CTD casts at each of the mooring sites, and to recover six subsurface hydrophone moorings in an NSF funded study (the cruise was co-chartered by NSF). The cruise track passes through the climatologically significant Tropical North Atlantic region, including the southeast corner of the subtropical North Atlantic (a region of subduction for the subtropical cell circulation); the Guinea Dome and oxygen minimum shadow zone where the subtropical and tropical gyres meet, and the Tropical Atlantic current system and equatorial waveguide. All major scientific goals of EN-550 were achieved.

This report contains data from R/V Sikuliaq cruise SKQ201617S to the eastern tropical north pacific oxygen deficient zone. The objective of the cruise was to study denitrification and anammox processes. The cruise took place between December 2016 and January 2017 in an area bounded by 25N-14N and 112W-104W. Two data sets are included. The first is the 1-meter binned CTD data while the second is the bottle cast data and contains nutrient values for nitrate, nitrite, silicate, phosphate and ammonium. The data were collected as part of NSF grant number 1542240 to Gabrielle Rocap, Rick Keil, Allan Devol, and Curtis Deutsch. CTD data has been reprocessed and aligned and outliers have been removed. Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html). All data are considered final. Data files provided in CSV format.

This dataset contains water temperature, salinity, and other parameters collected by CTD from research vessel Sally Ride, cruises SR1706 and SR1707, offshore California from 2017-03-05 to 2017-03-11. These cruises had, among others, the objective to service the CCE2 mooring (California Current Ecosystem). To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are available through the Rolling Deck to Repository (R2R) program, and the water sample data will be published via the Ocean Carbon and Acidification Data Portal at NCEI. Data are in netcdf format.

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.

This dataset contains surface and subsurface measurements of temperature, salinity, oxygen, current velocity, and other ocean environmental variables from the cruise Coriolis II in San Jorge Gulf (Argentina) in February 2014 using winched CTD, towed CTD, thermosalinograph, and ADCP, for the purpose of studying the frontal dynamics associated with a region of high tidal dissipation rates. The data are in text files (csv and cnv). The data are part of the PROMESse (Multidisciplinary program for the study of the ecosystem and marine geology of San Jorge Gulf and the coast of the Province of Chubut) international cooperation research program among the Ministry of Science and Technology (MINCyT), the National Scientific and Technical Research Council (CONICET), the Province of Chubut (Argentina) and the University of Quebec at Rimouski (UQAR/ISMER, Canada). Within the framework of this program, these data were collected during the second leg of Coriolis II cruise as a part of the MARES (Marine Ecosystem Health of the San Jorge Gulf: Present status and Resilience capacity) project.
