Conductivity-Temperature-Depth (CTD) data including Lowered Acoustic Doppler Current Profiler (LADCP) cast data. Nineteen full-depth CTD stations were occupied during cruise JR158, with one shallow test deployment. Each cast acquired measurements from a Seabird CTD and dissolved oxygen sensor, beam transmissometer, fluorometer, altimeter and 8x10 litre bottle rosette.
Forty surface drifters (drogued at 15m) were deployed from the ship during the cruise and subsequently tracked by satellite. Four ARGO floats were also deployed. These were programmed to drift at a depth of 1000m. They were also programmed to descend to 2000m and then resurface every 10 days in order to complete a full ocean profile
