PurposeResearch
ObjectivesA) To service an ADCP and a SmartBuoy at 53 32 N 3 21.8 W.
B) To obtain CTD profiles and water samples at the Coastal Observatory sites.
C) 25 hour CTD and water sample station at 53 32 N 3 21.8 W.
D) Side scan sonar survey in the vicinity of 53 32 N 3 21.8 W.
The cruise is the seventeenth in a series starting in August 2002 to maintain the moorings in objective (A) and to steam round the CTD grid in Liverpool Bay/the eastern Irish Sea, objective (B).
