CSIRO has deployed large oceanographic moorings near the South Pole to help scientists better understand ocean dynamics in the ice forming regions around Antarctica. A standard instrument on these moorings is an Acoustic Doppler Current Profiler (ADCP), which provides information on the direction and magnitude of ocean currents in the water column. These instruments use an integrated magnetic compass...
Measuring the surface mixed layer of the Southern Ocean is technically difficult due to the extreme weather conditions. A novel mooring with a surface expression has recently achieved engineering success in this harsh environment over a 6-month deployment. The mooring was the result of numerous prototypes and utilises a mixed design which includes a taut deep section, a long S-tether, a large mass/damper...
The Subtropical Front (STF) in the region south of Australia was surveyed to determine its location, character, and seasonal variation. The survey consisted of two cruises, during summer and winter of 1998, and used a towed CTD system (SeaSoar).Based on observations, the STF does not appear to be continuous between the Indian and Pacific Oceans in the region south of Tasmania during winter; instead,...
