Equipment Used: DGPS, Corer - piston, Grab sampler, Osprey camera system

Information to be Derived:

Summary of Activity and Data Gathered: 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.
