PurposeResearch
Objectives1. To service an ADCP and a SmartBuoy at 53 32 N 3 21.8 W.
2. To obtain CTD profiles and water samples at the Coastal Observatory sites.
The cruise is the 19th in a series starting in August 2002 to maintain the moorings in objective (1) and to steam round a CTD grid in Liverpool Bay/the eastern Irish Sea, objective (2).
