Summary Information for Field Activity 2000-070-FA

Area of Operations: Cape Cod Bay, Massachusetts, United States, North America, North Atlantic

Dates: August 17, 2000 to August 18, 2000

Chief scientist: Mike Bothner

Objectives: 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.

Type of Activity:

Information to be derived:

Summary: 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. Collected cores at Stations 6 and 7. Collected 3 Van Veen grab samples at Station 8. Samples from all 3 stations were gamma counted for radio-isotopes.
