To deploy: (c) A sea bed frame for a 600 kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves (d) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring with Sea-Bird MicroCAT temperature, conductivity loggers at 5m and 10m below the surface.

2) At 53 degrees 27 minutes N 3 degrees 38.6 minutes W (site 21, second site, B)
To recover: (e) A sea bed frame for a 600 kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves (f) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring.
To deploy: (g) A sea bed frame for a 600 kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves (h) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring.

3. To conduct a CTD / LISST survey of 34 sites every 5 miles covering the eastern Irish Sea between the North Wales coast and Blackpool and the Lancashire coast and the Great Orme, to determine the effects of the rivers Dee, Mersey and Ribble on Liverpool Bay.
4. To obtain calibration samples for salinity, transmittance, suspended sediment and for chlorophyll at selected stations.
5. To obtain near surface and bed water samples for nutrient and suspended sediment determination.
6. Collect 10 vertical net hauls at mooring site A.
