ObjectivesThe objectives of this cruise were:
(1) To service current meter moorings at SMBA stations F, M (deep water) and R (shelf edge). Moorings recovered, but not relaid.
(2) To service IOS moorings at four stations in the northern Rockall Channel. Stations could not be visited due to bad weather.
(3) To work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section plus additional CTD sections in the northern Rockall Channel. Stations O to T worked, covering from the slope and outer Hebridean continental shelf plus two sections across the Little Minch and North Minch.
(4) Collect large volume surface water samples for radiocaesium analysis with CTD profiles on the sampling stations. Accomplished with CTD profiles on nine of the ten stations.
