Conductivity-Temperature-Depth (CTD) profiles collected onboard ship during multiple cruises in the Southern Ocean between Oct 2002 and Jan 2006.
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
Lowered Acoustic Doppler Current Profiler (LADCP) and Conductivity Temperature Depth (CTD) data collected aboard the RRS James Clark Ross during cruises JR80 and JR110 in 2004. Data were used to calibrate instruments on four ocean moorings deployed in Shags Rock Passage, Scotia Sea. Four CTDs were used during JR110. Data includes continuous ocean profile data (surface to sea floor); temperature, salinity, pressure, current.
Argo floats measure temperature and salinity. Seven floats were deployed in November 2004 from the RRS James Clark Ross cruise JR110. Data were transmitted automatically to the British Oceanographic Data Centre (BODC).
Discrete ocean temperature, salinity and current measurements at four locations in Shag Rocks Passage. Moorings were deployed at 4 locations in Shag Rocks Passage (5255.6700S, 4745.5500W), (5255.6530S, 4745.9920W), (5302.5100S, 4802.7700W), (5302.5100S, 4802.3130W), (5309.0180S, 4829.9480W), (5318.2510S, 4854.8280W) from cruise JR080 in May 2004 and recovered on cruise JR110 in November 2004.
