| Winch Notes:
CTD winch will be used for OBS lowering. Trawl winch will be used for dredging. Need swivel for dredge. Traction winch required for dredging. Need 3 WHOI rock dredges. Lee Ellett (SIO) is sending 3 SIO rock dredges with weaklinks. We need 2 x 12 kHz Pinger for wire use (1 ready spare). We would like confirmation of the condition of the winch ahead of the cruise. How recently has it been used? Where there any issues? | |||||||||||

| CTD Winch with .322" Electro-mechanical wire | |||||||||||
| Winch Notes:
We would like to confirm the condition of the wire: What is the wire age? When was the wire last pull tested? When was the wire last unspooled to a seafloor depth of 5000 m, the maximum depth for our dredging? Is the level wind working? | |||||||||||
