To deploy: (h) A sea bed frame for a 600 kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves (i) A CEFAS SmartBuoy (with cellulose bags and trace metal monitor) 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. To obtain trace metal water samples. 7. Collect 10 vertical net hauls at mooring site A. 8. To deploy a directional wave buoy at 53 degrees 23.5 minute |
