12 days of wamos data. Need more information about how they process the WAMOS data and what they want for data. Also, 24/7, or just on station? rsl
All acoustics off for certain time periods, including ships doppler. What can be on/off will vary depending on distance from the instrument. rsl EK 80. Interested in observing, but no data will be recorded. rsl | |||||||||||

| Other required equipment and special needs: Mob/Demob Special Requirements: We will unload the container on the dock and will need a large forklift (> 5000 lbs capacity). We can operate the forklift if allowed, otherwise we will need an operator. Need ship crane support to load equipment on ship (max load 5000 lbs). We will plan to store the empty container on the dock if allowed, otherwise we would need to store on the ship for the experiment. | |||||||||||

Checklist | |
| 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. | |
