Title:
Data of field activity P-1-94-AR in Arctic Ocean from 07/25/1994 to 08/30/1994
Abstract:
Chief Scientist: Art Grantz. Data (pistoncore, boxcore) of field activity P-1-94-AR in Arctic Ocean from 07/25/1994 to 08/30/1994, <http://walrus.wr.usgs.gov/infobank/p/p194ar/html/p-1-94-ar.meta.html>.
Supplemental_Information:

Equipment Used -
pistoncore
boxcore
Notes -
(From 8/12/94 USGS Bulletin) August 10,1994. Art Grantz sends the
following progress report: We are working north near 82d N, 175d E doing mainly
biologic studies of the water column, benthic biology, sea ice studies, and
air and upper water column chemistry. The geologic program has been collecting
the required global change piston and box cores, but no seismic data to date.
At least two of our piston cores are about 28 ft. long, but none have reached
bedrock. Erk Reimnitz is having a field day on and in the ice. Sea ice
conditions were moderate early on, but fairly difficult now. However,
satellite imagery suggests that ice conditions are somewhat easier to the
northwest, over Wrangell Abyssal Plain, where we are now headed. We will try
to concentrate our seismic and coring program on prime geologic targets between
85d N and the Pole and 150d and 175d W.
Worked from Point Barrow to the North Pole. Two ships are involved, the U.S.
Coast Guard ship Polar Sea and Canadian Coast Guard ice-breaker Louis S. St.
Laurent. Geologic sampling and seismic reflection studies were conducted in
the55-day expedition across 3,700 miles of Arctic Ocean. Some cores came up
bubbling so they were sealed in pressure vessels to test whether they might
contain gas hydrate.
