Purpose
|
|
Climatic history of the western Arctic Ocean basin; Origin of
|
|
the Amerasia Basin, Arctic Ocean, and its continental margins.
|
|
Paleoclimate of Amerasia Basin, Arctic Ocean;
|
|
geologic framework, Arctic Basin

Summary
|
|
Collected 18 box cores; 16 piston cores; 17 bulk sediment samples were
|
|
collected from ice flows; 7 bulk sediment samples were collected for
|
|
radionuclide testing; 3 wood samples were collected; 38 samples were filtered to
|
|
determine suspended particulate matter concentration (29 were ice core samples,
|
|
6 were snow samples, 3 were water samples)

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.
