PurposeResearch
ObjectivesA) To service an ADCP mooring and a Smartbuoy at 53 32N 3 22W.

B) To deploy an ADCP (Combined setup, for turbulence) & ADV mooring 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 49th 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 (D).
