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 were:
1. To deploy and recover mooring arrays in the North Channel and western Irish Sea.
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 trials of the new Valeport, MAFF sponsored, U-Tow.
5. Lay a short period (1-2 weeks) mooring at a site currently occupied, in order to evaluate the performance of the new Valeport BFM308 current meter in a comparison with an Aanderaa current meter.
6. Conduct a test deployment of a NAS 2 nitrate analyser on the same mooring as the Valeport.
7. Recover POL ADCP and perfom a 12 hour trial of a second ADCP in the North Channel.
