RV Knorr Cruise KN221-02, 9th July – 1st August 2014. OSNAP Mooring Cruise Report

This cruise report details the scientific programme for SAMS led by Professor Stuart Cunningham of the Scottish Association for Marine Science (SAMS) on R/V Knorr cruise 221-02. Cruise 221-02 is a contribution to the international Overturning in the Subpolar North Atlantic Programme (OSNAP). Three additional scientific teams (from Rosentield School of Marine and Atmospheric Sciences, Royal Netherlands Institute for Sea Research, and Woods Hole Oceanographic Institution) participated on this cruise. SAMS objectives were to deploy moorings in the Rockall Trough, measuring temperature, salinity, currents and bottom pressure and; deploy Seaglider SG604 “Jura” in the Hatton-Rockall Basin. The OSNAP array as deployed between June and August 2014 is purposefully designed to provide a continuous record of the full-water column, trans-basin fluxes of heat, mass and freshwater in the subpolar North Atlantic, on a section from Newfoundland to Greenland to Scotland.
