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.

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.

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.

This dataset reports presence or absence data and other environmental cruise data collected in the Gulf of Mexico during R/V Pelican cruise PE18-01 (LF2017A) from 2017-07-01 to 2017-07-04. Larvae were collected with paired 61-cm bongo nets with 333 and 500-micron mesh. General Oceanics Flowmeters (Model 2030R, Miami, FL), were placed within net frames to determine the surface area sampled by each net. Fish larvae and early juveniles collected with net gear were preserved onboard in 95% ethanol. The dataset includes sampling and identification of larval fishes from epipelagic tows and environmental data (temperature, salinity, dissolved oxygen) from 47 stations. 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).

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.

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.

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 profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other parameters collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the R/V Pelican cruise RAPID 3 (EXPOCODE 32PE20180319), in the Gulf of Mexico from 2018-03-19 to 2018-03-23. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP) and the Climate Program Office.

This package contains underway and station data collected during R/V Pelican cruise PE17-23 in the Gulf of Mexico. Data included are six expendable bathythermograph (XBT) profiles of temperature, resistance, and sound velocity, as well as underway measurements of barometric pressure, relative humidity, and light transmission. Additional underway measurements and CTD station measurements are available in NCEI Accession 0172092. Provisional underway measurement locations are provided as interpolated from navigation data available in that accession. These data were collected by Natalia Sidorovskaia of the University of Louisiana at Lafayette as part of the Littoral Acoustic Demonstration Center - Gulf Ecological Monitoring and Modeling (LADC-GEMM) multi-year passive acoustic monitoring initiative in the Gulf of Mexico.
