Sea floor mapping (using multibeam sonar and deep-towed camera) and sampling (by dredge and trawl) of fossil and live cold-water corals for paleo-oceanographic and ecological studies.
Location
Drake Passage, Southern Ocean;
Summary
Multibeam bathymetry was collected continuously. 6 TOWCAM transects completed. 3 CTDs completed. 51 trawls and dredges deployed and rocks, corals, and other animals photographed and preserved. See bound cruise report for more information.
Comments
All multibeam and photographic data and fossil coral specimens will be archived at WHOI. Modern coral specimens will be archived at University of Hawaii. A separate scientific party from the University of Texas shared the shiptime. They collected multibeam bathymetry, underway magnetics and multichannel seismics and dredged rock samples. Those data are not part of this project and are archived at Univ. of Texas (PIs: Ian Dalziel and Larry Lawver). Original Center People field contained: Kathy Scanlon (co-PI, Geologist); Dann Blackwood (Photographer).
Project = Drake Passage Habitats, Drake Passage Habitats
198 biologic and geologic samples collected by deep-water dredge and/or tow processes: samples include fossil corals, sponges, forams, other biology, dropstones, ferromanganese crusts, sediments, and water samples.
