PurposeResearch
ObjectivesThe Dynamics of the Orkney Passage Outflow (DynOPO) cruise had two main goals:
1. Conduct measurements of the hydrographic properties, velocity and turbulent processes of the Antarctic Bottom Water outflow along its pathway through the Orkney Passage region
2. Turn around a set of long-term moorings deployed in the area by BAS and LDEO scientists, including recovery of additional instruments on some of the moorings deployed by DynOPO investigators 2 years previously.

Operations were generally successful. With regard to goal 1, a total of 120 hydrographic and/or microstructure stations were occupied across the study region; 3 focussed surveys of two major sills in the area were performed with the autonomous underwater vehicle Autosub Long Range; and an array of moored sensors measuring turbulent processes at high spatiotemporal resolution was deployed for the duration of the cruise, with partial instrument failures. In respect of goal 2, all moorings were successfully recovered and re-deployed, and the return of additional DynOPO instruments was close to 100%.
