Abstract
|
United States Geological Survey, Woods Hole, Massachusetts.
Chief Scientist: M. Bothner W. Martin, WHOI. Data (Camera-B/W
video, Scuba, Pole corer, diver operated push core barrels.,
The divers collected the required samples with excellent,
quality and in a short amount of time. We used a kayak to
make a, 3-point mooring which was very effective in holding
the boat on, location. This gave us perfect conditions to
test the pole corer in, these sediments with poor results as
described below.) of field activity 06028 (R-1-06-BH) in
Hingham Bay, Boston Harbor, Massachusetts, United

Purpose
|
|
Collect sediment cores at one station in Boston Harbor
|
|
(Hingham Bay) for pore water analysis and for lab-based erosion
|
|
studies.

Summary
|
|
Approximately 7 cores were collected by divers and in the
|
|
laboratory processed for pore water profiles, erosion experiments,
|
|
and resistivity.

Notes
|
|
Rafael was launched near Hingham on October 10 and be tied up
|
|
overnight at a floating dock next to the Ferry Boat dock. The pole
|
|
core was tried twice without satisfactory results. For pole cores
|
|
we restricted penetration to about 30 cm to fit the sediment core
|
|
into the erosion chamber. This did not penetrate firm enough
|
|
sediment to make a plug of mud at the bottom of the core (the
|
|
surface had very high water content). The sample partially fell out
|
|
of the bottom of barrel before we could get the piston into the
|
|
barrel just below the sea surface using Dann s long arm. The push
|
|
corer worked ok in Falmouth Harbor sediments with a barrel pushed
|
|
into maximum sediment depth.
|
|
1 days at sea.
