| Short name | PD34/03 |
| Objectives and Narrative |
Objectives
1. At 53deg 32'N 3deg 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 are 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 to measure the mean current profile, pressures and directional waves. A pressure recorder, a transmissometer/ conductivity/temperature logger and a SeaBird MicroCAT are also fitted to the frame. In addition, a 1.2 MHz ADCP interfaced to a SeaBird MicroCAT (RS-485 interface) was fitted for trial purposes (d) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and conductivity logger at 10 m below the surface (e) A toroid with Orbcomm instrumentation in trial mode. 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 and for chlorophyll at selected stations. All of the mooring objectives were accomplished and all 34 CTD sites were visited. |
