Field Activity T105AA

Identifier T105AA
Alternate names T-1-05-AA
Purpose Formation of continental crust, far western Aleutian Ridge and search for evidence of linked hydrothermal circulation
Description University of South Carolina,Lamont-Doherty Earth Observatory,United States Geological Survey, Menlo Park, California,Moss Landing Marine Laboratories,University of Wisconsin. Chief Scientist: Gene Yogodzinski, University of South Carolina. Geophysical data (navigation) of field activity T-1-05-AA in Far western Aleutian Ridge, Kiska westward to Attu area from 07/13/2005 to 08/21/2005
Location Kiska westward to Attu area
Summary Pre-selected areas will be mapped with multibeam swath bathymetry, candidate targets identified and surveyed along SCS lines, targets dredge to recover young extrusive rocks along crestal region of far western Aleutian Ridge. NOTES: Rocks samples will be returned to University of South Carolina, Lamont-Doherty, and Wisconsin University. Seismic and mutlibeam data will be returned for storage at USGS, Menlo Park as part of our archive of Aleutian Ridge geologic and geophysical data Equipment used: Single-channel GI airgun, BA35, EM300 multibeam bathymetry, rock dredging
Info derived Chemistry and age of recovered young igneous rocks
