Other ID: NBP-1103
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
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.
Start Port/Location: Punta Arenas, Chile
End Port/Location: Punta Arenas, Chile
Start Date: 2011-05-09
End Date: 2011-06-11
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.
Notes: No data archived at USGS. 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.
