PurposeResearch
ObjectivesA) To service an ADCP mooring and a Smartbuoy at 53 32N 3 22W.
B) To service an ADCP mooring and a Smartbuoy at 53 27N 3 39W.
C) To obtain CTD profiles and water samples at the Coastal Observatory sites.
D) To recover a current profiler at 53 32N 3 22W.

The cruise is the 29th in a series starting in August 2002 to maintain the moorings in objective (A+B+D) and to steam round a CTD grid in Liverpool Bay / the eastern Irish Sea, objective (C).
