Objectives

The work is directed at a better understanding of the dynamics of the North Channel which control the flushing characteristics of the Irish Sea. Net outflow from the Irish Sea is northward but there are apparently long periods of inflow on the western side of the channel. It is not known to what extent outflowing water recirculates and extends southward along the Irish coast or what importance inflows of Atlantic water have on flushing characteristics of the region. Variability in the flow regime and factors governing it are poorly understood. The main sampling aims of the cruise are:
1. To lay and turn round mooring arrays in the North Channel and western Irish Sea, thereby monitoring the flow regime.
2. Deploy and retrieve free floating ARGOS buoys in the North Channel and western Irish Sea to determine the Lagrangian circulation.
3. Undertake associated physical and biological surveys of the region in support of 1) and 2).
4. Perform further trials of the SCANFISH, aimed at meeting the specification defined prior to purchase.
