Purpose
Collect cores at long term monitoring stations in Cape Cod Bay.  This
work supports the Outfall Monitoring Program and is scheduled on short notice to
collect samples before the outfall begins on September 6, 2000.
Information to be Derived
Samples, radioisotopes.
Summary
Collected cores at the stations 6 and 7.  Collected 3 Van-Veen grab
samples at station 8.  Samples from all 3 stations were gamma counted for
radio-isotopes.
Notes
Hydro wire (3/16 inch) was used at station 8 where water depth is 200m.
This wire parted on the second deployment of the slow corer.  Although the wire
looked good and was tested (at the bitter end) and found to be of rated strength
(3500 ?), it parted on the return trip from the bottom on the second cast.   No
evidence for a kink or a problem with the shieve.  I learned later that the wire
was at least 10 years old (predated Olmstead) so perhaps there was hidden
corrosion.  Next time, insist on a safety factor of 5 when lowering equipment to
the bottom.
Got Help? For 00070, we would appreciate any information on -- analog materials, contract, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, owner, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
