Objectives

1. Recover 8 moorings after their deployment in April 1993 between the Agulhas Plateau and Crozet Islands.
2. Survey the Agulhas, Subtropical and Subantarctic Fronts between 30E and 50E and occupy a complementary section across the Agulhas Current.
3. Survey the Subantarctic Zone north of the Crozet Plateau between 30E and 50E with CTD (plus oxygen, nutrients and CFCs), SeaSoar and acoustic Doppler current profiler.
