Objectives

Objectives

A. To service a sea bed ADCP frame and SmartBuoy mooring at 53 32N 3 21.8W.
B. To service an 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.
D. To recover a wave buoy at 53 23.6N 3 14.2W.

The cruise is the 69th 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). Objective (A), (B) and (D) were achieved. Measurements were made at 29 out of a possible 34 sites for objective (C).
