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 data collected during the Life on the Edge II (SJ0403) cruise, June 8-22, 2004, aboard the Harbor Branch Oceanographic Institution's research vessel Seward Johnson. The cruise was coordinated by the NOAA Office of Ocean Exploration. The science team studied both the outer-shelf hard grounds, found in relatively shallow water (80 to 200 m), and the middle-slope coral banks, found in deeper water (350 to 800 m). Some of the data in this accession came from the Virtual Integrated Data System (VIDS) installed on the Seward Johnson, collecting data from shipboard instruments including meteorological sensors, TSGs, GPS, and others. Beyond the beach and influenced by the Gulf Stream, the unique habitats along "the edge" of the continental shelf and the deeper continental slope support myriad life forms. The Life on the Edge 2004 mission, part of a several-year study, aims to document and understand these habitats and the species that live in them. The mission team is searching for coral reefs and other reef habitats, from the sargassum floating in the surface waters to the corals found in deep water. The scientists hope to characterize the trophodynamics (energy flow) and community structures in these environments.

This data set contains hydrographic data collected during cruise SJ0609 in the tropical North Atlantic. Leg 1 of the cruise began in Ft. Pierce FL with a rapid transit to Bridgetown, Barbados and two hydro stations (001-002) en route. Leg 2 extended from Barbados to Mindelo, Cape Verde, with nine hydro stations (003-010, 012). Leg 3 included a run south to the equator, then northwestward to Barbados with eleven hydro stations (013-023). Repeated casts at a single station are identified with a sequence number following the decimal. For example, the first sampling event at station 022 is numbered 022.01, the second is numbered 022.03, etc.

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.

The diverse ocean-bottom habitats off the coast of South Carolina and Georgia support a corresponding diversity of organisms. An imaginary line, or transect, running from the coast of Georgia to the edge of the continental shelf off South Carolina would cross these habitats: coastal sands washed down from the land; emergent, hard-bottom, rocky outcrops on the continental shelf; the soft muddy sediments on the upper Florida-Hatteras Slope; and the complex bottom topography of the Charleston Bump on the Blake Plateau. Beyond the Blake Plateau lies the deep ocean, or the abyss. The waters overlying the transect change as well. They become increasingly less influenced by local climate and runoff from the land, and more influenced by tropical currents of the Gulf Stream, as you move offshore. Scientists on the Estuary to the Abyss Expedition will research the habitats and fauna along this line, which we refer to as the "Latitude 31-30 Transect." Sponsored by the NOAA Office of Exploration, the expedition team will work aboard Harbor Branch Oceanographic Institution's research vessel, the Seward Johnson, which carries and deploys the deep submersible vehicle, the Johnson-Sea-Link II. For nearly a half-century, fishery scientists and marine ecologists have conducted research and monitoring of many of the near-shore marine and estuarine habitats off the coast of the southeastern U.S. Historically, most of these research efforts have been aimed at waters inshore of the Florida-Hatteras Slope, where productive shelf waters support important fisheries for snappers, groupers, and other reef fishes. The deeper waters beyond the Florida-Hatteras Slope have been studied less. The Estuary to the Abyss cruise will concentrate on deeper waters (those greater than 400 m) along the transect. Our research will complement previous studies of shallow-water faunas. We will examine changes in faunas that occur with increasing depth and distance offshore. The exploration along this transect will also help us understand the influence of several variables -- including distance from land (and its human inhabitants), bottom type, and overlying water masses -- on the assemblages of organisms that dwell on the bottom. Overall, we will expand our knowledge of bottom faunas from the estuary to the deep sea.
