This data set contains oceanographic data (CTD Data, Fathometer, Knudsen echo sounder, Mocness plankton tow net, Oxygen, and Salinity). The researchers used a submersible, a remotely operated vehicle, and other technology to assess and record conditions in the water column and on the seafloor to gather baseline data along Florida's shelf edge.

This dataset contains oceanographic data (ADCP Lander, Chemical, CTD, ROV, SCS), biological images and videos, and documentation. This project involves a comprehensive multidisciplinary study to explore and characterize two deep coral habitats with contrasting benthic communities on the west Florida slope of the Gulf of Mexico, including the testing of newly developed sensors deployed on an ROV to map and fully resolve the carbonate system at the sites.

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 contains oceanographic data (ADCP, CTD, underway), submersible data, images, and documentation. The cruise focused on several seep sites, canyons, and hard bottom features located less than 100 nm offshore. The goal of this expedition was to validate several seep targets, image and map seeps, canyons (e.g., Keller, Pamlico, Hatteras, and unnamed canyons), and hard bottom features located between Virginia and Georgia.

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 cruise used the remotely operated vehicle (ROV) Jason II to: explore 4-6 new sites for the occurrence of deep water coral reefs; made collections of Lophelia and other corals for genetic and physiological studies, made collections of communities associated with Lophelia and other corals for ecological studies; collected quantitative digital imagery for characterization of sites and coral communities; collect spatially explicit physical near bottom oceanographic data; deploy cameras and microbial arrays; reposition larval traps and current meters; collected push cores; and conducted a series of linked archaeological/ biological investigations on deep water shipwrecks.
