USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2008-004-FA

Other ID: NBP0805; P-1-08-AN

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: Drake Passage, Southern Ocean;

Principal Investigator(s): Kathryn Scanlon Catanach

Affiliate Investigator(s): Laura Robinson, WHOI

Information Specialist(s):

Data Type(s): Environmental Data: CTD, Imagery: Photo, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Multichannel, Sonar: Single Beam

Scientific Purpose/Goals: 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.

Vehicle(s):

Start Date: 2008-04-18

Start Port/Location: Punta Arenas, Chile

End Date: 2008-05-25

End Port/Location: Punta Arenas, Chile

Equipment Used: Echosounder, Camera- deep sea, Grab sampler, CTD, Digital camera, GPS (wh), Multichannel seismics

Information to be Derived:

Summary of Activity and Data Gathered: 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.

Staff: Dann Blackwood, Kathryn Scanlon Catanach

Notes: 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).
