Purpose
|
|
Coop w/ NBS to determine the geological
|
|
characteristics of the fjord floor where NBS has been studying crab and
|
|
halibut distributions.
|
|
|
Information to be Derived
|
|
Character of fjord floor -- morphologic, sedimentologic,
|
|
stratigraphic, (depth to acoustic basement, isopachs of sedimentary
|
|
units, location of bedrock outcrops and large glacial erratics,
|
|
differentiating sand and mud substrates, identifying bedforms, etc).
|
|
|
Summary
|
|
Insonified fjord floor at 6 study sites in lower Glacier Bay (Bartlett
|
|
Cove, Berg Bay, Sitakaday Narrows, submerged ridge between Drake and Francis
|
|
Island, and 2 sites in the Beardsley Islands--1st north along Link Is., 2nd
|
|
south near Eider Is.).

Notes
|
|
REPORT FROM ALASKA (from 8/30/96 WRUSGS Bulletin)
|
|
Dave Hogg, John Gann, Terry Bruns, and Paul Carlson joined forces
|
|
with our new siblings from National Biological Service (NBS) and our
|
|
cousins from the Park Service for a productive 10-day (8/1-10)
|
|
sidescan-sonar (SSS) survey in Glacier Bay, AK. We collected 500 kHz
|
|
SSS + 3.5 kHz profiler data in five portions of Glacier Bay National
|
|
Park. The areas insonified are Dungeness Crab and Halibut study
|
|
sites. We will provide seafloor habitat interpretations that the
|
|
biologists hope will explain distributions of those two commercial
|
|
resources. We were fortunate to be able to sample some of the very
|
|
tasty resources as well. In one study area, to the biologists' glee, we
|
|
obtained good imagery of a sunken skiff that the Skipper of the R/V
|
|
Quillback identified as "Tommy's boat," and we also saw a pile of
|
|
Tommy's crab pots a short distance away (overloading of pot +
|
|
choppy seas = sinking). Bruns even saw the sun one day and realized
|
|
his wish to see the eastern side of the Fairweather Range (beautiful view).
