Cruise identifierPD41/05
Cruise period2005-10-26 — 2005-10-27
StatusCompleted
Port of departureMenai Bridge, United Kingdom
Port of returnMenai Bridge, United Kingdom
PurposeResearch
ObjectivesA) To service an ADCP mooring and a Smartbuoy at 53 32N 3 22W.
B) To service an ADCP mooring and a Smartbuoy at 53 27N 3 39W.
C) To obtain CTD profiles and water and sediment samples at the Coastal Observatory sites.

The cruise is the 31st 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).
