Abstract

Talisker (SAMS Seaglider 156) was deployed west of Tiree on 12 October 2009, to undertake SAMS exploratory mission to monitor the Ellett Line in the North Atlantic using a glider rather than a ship. She was equipped with a Seabird CTD and Oxygen sensor as well as a Wetlabs fluorometer with red and blue backscatter sensors. Before recovery on 9 March 2010 she had made 789 dives, completed four crossings of the Rockall Trough and covered over 3000 km. Although the end of the mission was forced by a failure of the roll motor, by then all objectives had been completed and the glider was about to return home. The mission has thus been judged a success, and marks the start of remote monitoring of the North Atlantic by SAMS.
