1. To deploy 22 hydrographic/velocity moorings comprising two arrays near Cape Farewell, Greenland: one extending across the east Greenland shelf and slope (the OSNAP East Irminger array), and one extending across the west Greenland shelf and slope (the OSNAP West eastern Labrador array).
2. To deploy 3 sound source moorings for the OSNAP RAFOS float program in the Labrador and Irminger Seas.
3. To carry out a shipboard hydrographic/velocity survey of the region near Cape Farewell, Greenland, including transects along the two mooring array lines.
4. To launch acoustically tracked RAFOS floats at a number of sites near the mooring array lines.

All of the above objectives were successfully met. 25 moorings were deployed, 196 conductivity‐temperature‐depth (CTD) stations were occupied, most of them with a lowered acoustic Doppler current profiler (ADCP) and 18 RAFOS floats were launched. The vessel‐mounted ADCP was operational throughout the cruise and returned a full data set.
