Notes
REPORT FROM THE LANEY CHOUEST OVER THE BLANCO FRACTURE ZONE
(FROM 8/30/96 WRUSGS BULLETIN)

Jim Hein and Michelle Greene are participating in a cruise
organized by NOAA under the direction of Bob Embley. We are
studying diffuse-flow hydrothermal mounds in an extensional
basin on the Blanco Fracture Zone off the Oregon coast. The
mounds are composed of gold- and silver-rich bacterial mats
that have been replaced by silica and iron oxides. After some
delays readying the ATV (Advanced Tethered Vehicle), the
system is now transiting the seafloor and is working well,
providing excellent video and collecting core samples of a
mound with a measured internal temperature of 40 degrees C.
It took about 12 hours of ATV search to locate the mound that
was first seen on our USGS video camera sled in 1994.
Additional ATV and Sea Cliff submersible dives will follow
during the next week. Seas are calm and the wind is a mere
breeze.
Got Help? For C-1-96-WO, we would appreciate any information on -- analog materials, contract, days at sea, dive count, funding, information specialist, information to be derived, kms of navigation, national plan, NGDC Info, organization, owner, ports, project, project number, publications, scanned materials, seismic description, station count, station description, submersible, summary, tabulated info.
