CRUISE PLAN
Mooring array
- The mooring array will be deployed so that the Undercurrent is monitored throughout the experiment.
- The mooring array will be short and cover only the AUC. The array will be placed along the 32°S section, the three moorings at depths of 1800 m, 2400 m and at the foot of the slope, 2900 m.
- The shallower mooring should capture the core of the northeastward flow, which in all the LADCP sections thus far appears between 1000 and 1500 m deep. These depths are important for transport of AAIW.
- The deeper moorings will better capture the extent of the NADW flow, which though not so swift, covers a greater area and thus contributes significantly to the flux.
- The shallowest mooring will have two instruments at 400 and 700 m (1400 and 1100 m depth) off the bottom.
- The second mooring will have instruments at 200, 600 and 1000 m off (2200, 1800 and 1400 m depth) and the third at 100, 400 and 700 m above the sea bed (2800, 2500 and 2200m depth).
