PurposeResearch
Objectives1. At 53° 32´ N 3° 21.8´ W, half a mile west of the Mersey Bar Light Vessel -
To recover: (a) A CEFAS wave buoy (replace batteries) (b) 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 (c) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and conductivity logger at 10 m below the surface (d) A surface torroid (Telemetry buoy) with an acoustic modem and an Orbcomm satellite communication system (e) A sea bed frame for a 600 kHz ADCP (Telemetry ADCP) to measure mean current profile and pressures. An acoustic modem was also fitted and linked to the ADCP.
To deploy: (f) Deploy a Rapid Lander (on test - recovery planned 2 March) (g) 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 (h) 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 (i) A CEFAS wave buoy (j) A sea bed frame for a 600 kHz ADCP (Telemetry ADCP) to measure mean current profile and pressures. An acoustic modem was also fitted and linked to the ADCP (k) 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, suspended sediment and for chlorophyll at selected stations. To obtain water samples for nutrient determination.

Most of the mooring objectives were completed and most of the CTD sites were visited.
