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 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.

Despite substantial interference from hurricanes Bonnie, Charley, and Katrina, Operations Deep-Scope 2004 and 2005 were extremely successful. In addition to numerous discoveries (e.g., fluorescent sharks, new large deep-sea squid, UV vision in deep-sea crabs, the importance of polarized light and bioluminescent searchlights), these expeditions developed several new technologies. The Eye-in-the-Sea is now a robust stealth camera system; waveband, fluorescence, polarization, and UV imaging techniques are well-developed; and we can now collect deep-sea benthic species without damaging their eyes. Together these achievements place us in a unique position to explore the deep sea in innovative and exciting ways. In 2007 we propose to extend the envelope of this exciting frontier in ocean exploration in two ways: 1) developing further imaging and listening technologies, 2) using the currently developed methods to explore the cliffs in the Bahamas that range from the surface to 3000 feet in depth. Results from this proposal will characterize an important deep-sea benthic environment, and use new technologies to locate inorganic and organic ocean resources, fulfilling two of the main themes of Ocean Exploration. The proposed cliff sites range from shallow coral reefs to the abyssal plain and will allow us to explore a large number of benthic communities in a small location and learn how depth affects undersea life. Given the technological focus of our research however, if the ships' schedules should make it difficult to work in this area we would welcome the opportunity to test these new technologies at any biologically rich sites. Unlike many research cruises, which focus in depth on one problem and method, we propose a number of smaller projects that are linked by the methods and questions of visual ecology and optical oceanography. The ultimate goal of our highly interdisciplinary group of researchers is to explore and characterize the deep-sea world in these new ways.

This dataset includes CTD, ADCP, and other data from the Life on the Edge 2003 cruise collected in the Atlantic Ocean on the outer continental shelf of the Carolinas. These data were collected from NOAA Ship Seward Johnson and unmanned ROV Johnson-Sea-Link II by NOAA Office of Exploration from August 16, 2003, through August 27, 2003.

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.

Physical and biological data were collected using fluorometer and CTD casts from the ROGER REVELLE in the Southern Oceans from 12 January 1998 to 03 February 1998. Data were submitted by Dr. Robert O'Malley of the College of Oceanic and Atmospheric Sciences, Oregon State University with support from the Joint Global Ocean Flux Study / Southern Ocean (JGOFS/Southern Ocean) project.
