Departure: Nov 24, 2017

Montevideo

Arrival: Dec 11, 2017

Montevideo

Operations Area

Argentine Basin
Lat/Lon: 42° 0.0′ S / 42° 0.0′ W
Depth Range: 3000 / 5200
Will the vessel be operating within 200 NM of a foreign country? No
Are visas or special travel documents required? no

Science Objectives

1)         Recover the Argentine Basin Surface Mooring, GA01SUMO-00003

2)         Recover the Argentine Basin Profiler Mooring, GA02HYPM-00003

3)         Recover the Argentine Basin Profiler Mooring, GA02HYPM-00002

4)         Recover the Argentine Basin Flanking Mooring A, GA03FLMA-00003

5)         Recover the Argentine Basin Flanking Mooring B, GA03FLMB-00003

6)         Recover glider (#364) that is adrift

7)         Conduct ship vs buoy meteorological comparisons at the Surface Mooring sites.

8)         Conduct CTD casts with water sampling at the recovery sites, including glider (except GA02HYPM-00002 to avoid entanglement with broken mooring).

9)         Ancillary projects include the deployments of 8 Argo floats and 2 drifters. Launch locations are TBD at the time of this writing, but are not to impact the work for OOI.

Science Activities

Five mooring ops (4 subsurface, one surface). Moorings are full depth (~5,200 m). One subsurface mooring has failed and dragging ops may be needed.
Acoustic communications will be important to establish status of moorings by talking to acoustic releases and to instruments on the mooring line at each mooring.
CTD casts with water samples will be done at each mooring (except failed one) to establish validation/calibration of subsurface instruments prior to recovery. One CTD cast will go down to ~5000m.
Comparison between meteorological and oceanographic (ADCP, TSG, CO2, fluorometer, etc) measurements from the ship and the surface buoy (SUMO 3). Will require ship to hove to 1/2 nm downwind of buoy for ~ 24 hours.
Recovery of glider that drifted away from OOI mooring array. CTD cast prior to recovery is desired.
Launching 8 Argo floats during transit.
Launching 2 surface drifters during transit.
