Menai Bridge, United Kingdom

Port of return

Menai Bridge, United Kingdom

Purpose

Research

Objectives

A) 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).
