Field Activity C294WO

Identifier C294WO
Alternate names C-2-94-WO,L-2-94-WO, L294WO
Purpose Investigate tectonic, magmatic, and hydrothermal processes along the Blanco Ridge, a strike-slip segment of the Blanco Fracture Zone
Description Chief Scientists: Randy Koski, Bob Embley, Stephanie Ross. Data (bathymetry, underwatercamera, underwatertelevision, core) of field activity C-2-94-WO in Blanco Ridge from 08/27/1994 to 09/06/1994
Location Blanco Ridge
Summary 67 hours of video tape, 1000 still photographs, Sea Beam bathymetry, 57 rock samples, 10 sediment cores
Comments (From Sept. 9, 1994 USGS bulletin) Randy Koski reports that during the first three days of their cruise aboard the LANEY CHOUEST (with Bohannon, Gray, Reid, Ross, Smith, and Tormanen) deployments of the U.S. Navys advanced tethered vehicle (ATV) and submersible DSV TURTLE have yielded 45 hours of videotape and about 25 rock samples from the south flank and crest of Blanco Ridge. Accumulations of volcanic rock fragments and evidence for rock avalanches on the Ridge flanks are consistent with the record of seismicity along this transform fault zone. This collaborative program with NOAA and the NAVY will continue through September 7, with final operations in the east Blanco Depression.
