PurposeResearch
ObjectivesObjectives
1. At 53° 32'N 3° 21.8'W, half a mile west of the Mersey Bar Light Vessel
To recover: (a) A sea bed frame for a 600 kHz ADCP to measure the mean current profile, pressures and directional waves. A pressure recorder, a transmissometer/ conductivity/temperature logger and a SeaBird MicroCAT were fitted to the frame (b) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and conductivity logger at 10 m below the surface.
To deploy: (c) A sea bed frame for a 600 kHz ADCP (Mean ADCP) to measure the mean current profile, pressures and directional waves. A pressure recorder, a transmissometer/conductivity/temperature logger and a SeaBird MicroCAT were also fitted to the frame (d) A CEFAS SmartBuoy in a single point mooring with a SeaBird MicroCAT temperature, conductivity logger at 5m below the surface and an Aanderaa temperature and conductivity logger at 10 m below the surface (e) A sea bed frame for a 600 kHz ADCP (Telemtry ADCP) to measure mean current profile and pressures. An acoustic modem was also fitted and linked to the ADCP (f) A surface torroid (Telemetry buoy) with an acoustic modem and an Orbcomm satellite communication system.
2. To conduct a CTD/LISST survey of 34 stations 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. To obtain calibration samples for salinity, transmittance, and for chlorophyll at selected stations. To obtain water samples for nutrient determination and grab samples of sediment.
3. At 53° 22'N 3° 55.4'W, Station 34 - to deploy a new WaveBuoy at Station 34 on the outbound leg and to recover it on the inbound leg.

All the mooring objectives were successfully accomplished and 34 out of 35 CTD stations were visited.
