USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2011-002-FA

Other ID: NBP-1103

Status: Completed

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

Funding Program(s):

Location:

Principal Investigator(s): Kathryn Scanlon Catanach

Affiliate Investigator(s): Laura Robinson, WHOI and Bristol University UK

Information Specialist(s): Kathryn Scanlon Catanach

Data Type(s): Environmental Data: CTD, Imagery: Photo, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Multibeam

Scientific Purpose/Goals: Collect multibeam bathymetry and seafloor photos to map and characterize possible cold-water coral habitats in the Drake Passage area. Fossil and live corals will be collected by dredge and trawl for paleoclimate and biologic studies. All data will be archived at WHOI and will be the responsiblity of Principal Investigator Dr. Laura Robinson. USGS (Scanlon) will have access to data for collaborative studies.

Vehicle(s):

Start Date: 2011-05-09

Start Port/Location: Punta Arenas, Chile

End Date: 2011-06-11

End Port/Location: Punta Arenas, Chile

Equipment Used: CTD, GPS (wh), Knudsen echo sounder 320B/R, Multibeam swath bathymetry, Trawl, Corer - gravity, Camera- deep sea

Information to be Derived: Samples and chemical analysis;Grain size analysis;Bathymetric maps;

Summary of Activity and Data Gathered: Multibeam data, biological samples, fossil coral samples, rock samples, and photographic data were collected from sites in the Drake Passage between South America and the Antarctic Peninsula. Sites ranged from shelf edge to deep ocean and included the following areas: Burdwood Bank, Shackleton Fracture Zone, West Antarctic Peninsula Shelf, Interim Seamount, Sars Seamount, and Cape Horn Shelf. In addition, 6 CTDs and 6 sediment cores were collected. Data collection on this cruise adds to the field work begun on NBP-0805 (2008-004-FA)cruise in 2008.
