CA 12-13 XXVIII Ita. Esp. New Zealand

TThe R/V Araon left the harbor of Lyttelton (NZ) on 24/01/2012 at 09:00.
XBT launches began on 25/01/2012 at 09:00, in correspondence of the 48th parallel south.
XBT were launched every 0.25 Nm (about 1h10m of navigation time), for a total of 54 probes. The acquisition was interrupted to the parallel 54° 15'due to bad sea weather conditions.

On 29/01/2012 at 03:00 taking advantage of the reduced speed of the ship to make measurements (magnetometry and CTD) it was possible to fix the launch system-acquisition position and then to start XBT operations at a latitude of 62°S, although intermittently. XBT operations lasted until ice presence imposed a final stop at 68.5°S.
