This dataset reports presence or absence data and other environmental cruise data collected in the Gulf of Mexico during R/V Blazing Seven cruises LF2016A and LF2016B from 2016-06-09 to 2016-07-28. Larval fishes in pelagic waters sampled from 48 stations were collected with three different gear types: 1) neuston net (2 m width x 1 m height frame) rigged with 1200 micron mesh; 2) paired 61-cm bongo nets with 333 and 500-micron mesh; 3) paired ring net with 1000 micron mesh. Other cruise data were collected at each site including latitude/longitude, date, time, environmental data (temperature, salinity, dissolved oxygen) and Sargassum dry weight. Sea surface temperature, salinity, and dissolved oxygen were measured at the surface of each station using a Sonde 6920 Environmental Monitoring System (YSI Inc., Yellow Springs, Ohio, United States).

Twenty-six conductivity, temperature and depth profiles from GISR (Gulf Integrated Spill Research Consortium) Mooring Recovery Cruise G04.

Chemical, physical and profile oceanographic data were collected aboard the PELICAN in the Gulf of Mexico from 2010-05-10 to 2010-07-21 in response to the Deepwater Horizon Oil Spill event on April 20, 2010, by the Subsurface Monitoring Unit (SMU), which consisted of multiple government and corporate agencies. These data include CDOM fluorescence, conductivity, dissolved oxygen, hydrostatic pressure, salinity, sound velocity, temperature and water density. The instruments used to collect these data included CTD, fluorometer and oxygen meter along with other physical sampling devices. More specific information about each dataset is located in their individual metadata records. The CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center (NCDDC). Cruise level information consisting of data management documents, cruise reports and plans, videos and pictures, and other miscellaneous documentation were gathered by the data managers.

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.

Sampling of in situ seawater, macroalgae, macrocrustaceans and associated fauna (cruise GoMRI-II, November 15-17 2012, stns 1-18, data available for all) aboard the R/V Pelican cruise id PE13-14 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.

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.

This dataset combines CTD and ADCP data submitted in a number of packages. Data were collected from the R/V Pelican during the cruise PE23_12_Pallas_Sanz in the central Gulf of Mexico. Data are in CNV, TXT, and NetCDF formats. This cruise is U.S. State Department MSR U2022-046 as part of the World Data Service for Oceanography.

This dataset contains short-lived radioisotope (SLRad), sediment core photographs, and sediment texture and composition data collected aboard R/V Weatherbird II cruises WB-0812 and WB-1012, and R/V Pelican cruise PE12-22 in the northern Gulf of Mexico from 2012-04-09 to 2012-10-18. Both SLRad data and sediment texture and composition data were generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to the base of cores. Sediment texture values were expressed as percent gravel, sand, silt, and clay. Percent of mud can be calculated by combining percent silt and clay. Sediment composition was expressed as percent total organic matter (TOM) measured by loss on ignition (LOI), percent carbonate content measured by acid leaching, and the percent insoluble residue (IR), which was likely dominated by terrigenous clastic (land-derived) sediment sources. For sediment-core photograph data, sediment cores were longitudinally split and photographed with a Nikon D5100 digital camera with a scale in metric units (cm and mm) for a visual representation of sediment stratigraphy, color, and visual properties.

This dataset contains CTD profiles and temperature profiles collected by expendable bathythermograph (XBT) collected from the R/V Pelican during cruise PE16-10 between 2015-10-27 and 2015-10-28. Measurements are reported from three stations and include temperature, fluorescence, oxygen, conductivity, salinity, and sound velocity profiles.
