Notes
|
(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. Navy's 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.
