PD02/05

Cruise period

2005-01-31 — 2005-02-01

Status

Completed

Port of departure

Menai Bridge, United Kingdom

Port of return

Birkenhead, United Kingdom

Purpose

Research

Objectives

A) To service two ADCP moorings and a SmartBuoy at 53 32 N 3 21.8 W
B) To obtain CTD profiles and water samples at the Coastal Observatory sites.
C) To deploy ADCP mooring at 53 27N 3 30.2W
The cruise is the 24th in a series starting in August 2002 to maintain the moorings in objective (A) and to steam round a CTD grid in Liverpool Bay/the eastern Irish Sea, objective (B).
