ObjectivesA. To service an ADCP mooring and a Smartbuoy at 53 32N 3 22W.
B. To deploy nutrient analyser at 53 32N 3 22W.
C. To service an ADCP mooring and a Smartbuoy at 53 27N 3 39W.
D. To obtain CTD profiles and water samples at the Coastal Observatory sites.

The cruise is the 42nd in a series starting in August 2002 to maintain the moorings in objective (A+B) and to steam round a CTD grid in Liverpool Bay / the eastern Irish Sea, objective (C).
