Objectives

Aims

A. To service a sea bed ADCP frame and SmartBuoy mooring at 53 32N 3 22W.
B. To service a sea bed ADCP frame and SmartBuoy mooring at 53 32.3N 3 38.4W.
C. To obtain CTD profiles, water samples and grab samples at the Coastal Observatory sites.

The cruise is the 74th 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).

Objectives A-C were all sucessfully completed.
