Planning parameters for profiling floats and CTDs

• 5 moorings - locations set • 20 CTD stations • 9 APEX floats - profiling to 1800 meters, 5 days, T/S/O2

• Planning guidelines– 1 APEX float at each mooring (5 floats) (float A1 - A5)

– 1 CTD station at each mooring (5 CTDs)

– 1 CTD station at each APEX float that isn't co-located with a mooring (4 CTDs)

– This leaves 4 floats and 11 CTD stations.

Parameters (continued)

• Placement of additional 4 floats:– A6: 1 float on outbound track just south of Gulf Stream– A7: 1 float on outbound track halfway between moorings C and B– A8: 1 float on inbound track (between Bermuda and mooring F) at

climatological deepest location of 17C isotherm– A9: 1 float on inbound track just north of Gulf Stream (?)

• Placement of additional CTD stations: – Sampling across southern half of Gulf Stream on outbound track: 4 stations

additional. Positions to be based on SST and altimetry maps– Sampling across southern half of Gulf Stream on inbound track: 4 stations

additional. Positions to be based on SST and altimetry maps (other info? XBT sections?)

• 3 other stations • 1 between moorings D and C: 37N 58.5W • 1 between moorings B and A: 32.5N 57W • 1 between mooring A and Bermuda: 31.5N 62W
