| |
Science Activities | |
1. Initial deployment of 7 bottom landers. 2. Recovery of first bottom lander on return trip, data download, and re-deployment. 3. Sound propagation experiments (12-18 hours) with ship deployed transducer after bottom lander deployment. 4. CTD casts in association with each lander deployment and multiple with sound propagation experiment. 5. Zooplankton net tows in conjunction with each lander deployment. 6.

Notes: As of 10/20/17, trawl net deployments were officially modified to be conducted off Armstrong Trawl winch with 9/16" wire. There is no longer a winch from the winch pool being brought to the ship. See attachment "Isaacs Kidd Midwater Trawl" |

SSSG Tech: | |
7 free-fall moorings. Each has a built-in anchor. They have no surface expression, and weigh about 600 kg each. The moorings will be pre-assembled and dropped from the A-frame. The science compliment will be close to maximum. They will have one person (Carmen) assigned as the mooring tech. There will be a hand lowered (5-10 meters) transducer (about 75 lbs). | |
Shipboard instruments required: EK80 - Yes Multibeam - Not critical, would like to us it to confirm landing locations CTD - They have some instruments that they would like to mount to the CTD frame with hose clamps after removing some bottles. The CTD will be used to calibrate the bottom lander. They have a mid-water net (450 meters) they would like to tow at 1-2 knots using the CTD cable. Expect about 14 CTD casts interspersed with net tows. Need to have plan to switch wire between blocks. |
