1. The main aim of this cruise was to deploy four sub-surface moorings offshore of Mossel Bay, along a transect crossing the central Agulhas Bank and in principle the Cold Ridge when formed. The instruments will measure currents and temperature throughout the water column. We intend to measure these parameters over a 5-month period with a recovery scheduled for end of March 2019. 2. Deployed satellite-tracked surface drifters (SVP) at the mooring locations. 3. Test all scientific equipment and instrumentation in readiness for the main survey in March 2019. 4. Train NMU students on data and sample collection at sea, as well as lab analysis back at NMU. Ideally, these limited data and samples will be contributions to student's research.
