Purpose
|
Collect sediment cores at one station in Boston Harbor
(Hingham Bay) for pore water analysis and for lab-based erosion
studies.
|
|
|
Information to be Derived
|
Samples and Chemical Analysis;
|
|
|
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.
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.
