Title:
Mooring Redeployment and Sampling data of field activity T-1-96-NC in Eel River Margin, Northern California from 07/13/1996 to 07/18/1996
Abstract:
Chief Scientist: Homa Lee. Mooring Redeployment and Sampling data (boxcore, pistoncore, CTDmeter, multibeam) of field activity T-1-96-NC in Eel River Margin, Northern California from 07/13/1996 to 07/18/1996, <http://walrus.wr.usgs.gov/infobank/t/t196nc/html/t-1-96-nc.meta.html>.

CORING ON THE HUMBOLDT SLUMP
Ken Israel and Homa Lee are aboard the new (and big!!!) R/V Thomas Thompson
on our way from San Diego to the STRATAFORM area on the Eel River Margin and
then on to Eureka. Our plans are to take box and piston cores on the slope in an
area that has been described as a giant submarine slump (Humboldt Slump). Last
summer a beautiful swath-bathymetry map of the area was produced, and ever since
we have been trying to explain all the features we observe on the map. We hope
the coring will help.
There are more ex-USGS employees on the cruise than present ones. Mark Holmes
and Byron Ruple are aboard, and the ship's master is Captain Al.
The weather is good and the whales are out. -- Homa Lee and Ken Israel


From Western Region Marine and Coastal Surveys Bulletin, July 26, 1996...


RECEIVED JULY 17 FROM THE THOMPSON
We have just finished 4 days of intense box and piston coring in the
STRATAFORM area off Eureka. We obtained 12 piston cores, each of which is about
7 m long. We also obtained 21 box cores, one at each of the piston stations plus
a few more. We are finding some turbidites and lots of gas in some of the piston
cores.
Mark Holmes has been a tremendous help to us. Food is good and the Thompson
rides great.
We are doing a one-day Hydrosweep survey of the deeper areas west of the
STRATAFORM area today, and we go to Eureka to unload tomorrow.
Cheers, Homa Lee and Ken Israel
