| Purpose | Research | ||||||||||||||||||||||||||||||||||||||||||||||||||||
| Objectives | 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 and pressures. A pressure recorder, a transmissometer / conductivity / temperature logger and a SeaBird MicroCat are fitted to the frame. B) A sea bed frame fitted with a 1.2 MHz ADCP, SonTek ADV, LISST-100 and Sontek coherent Doppler on loan. C) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and conductivity logger at 10 m below the surface. D) A development spar buoy. To deploy d) A sea bed frame for a 600 kHz ADCP to measure the mean current profile and pressures. A pressure recorder, a transmissometer / conductivity / temperature logger and a SeaBird MicroCat are also fitted to the frame (recovery a). E) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and conductivity logger at 10 m below the surface. 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 suspended sediment at all stations and for chlorophyll at selected stations. To obtain grab samples of sea bed sediment at selected stations. All the mooring objectives were successfully accomplished and 32 out of 34 CTD sites were visited. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
