PurposeResearch
ObjectivesObjectives

1. At Site A 53 32 N 3 21.8 W, (CTD station 1 and 9)
To recover
a) A sea bed frame containing a 600kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves, Sea-Bird SBE 16plus with pumped conductivity sensor, digiquartz pressure sensor and a SeaPoint turbidity sensor, SonTek ADV and Aanderra oxygen optode.
b) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring. Attached to the mooring wire are SeaBird MicroCat temperature, conductivity loggers at 5 and 10m below the surface and miniloggers at 7.5 and 15 m below the surface.
To deploy
c) an identical bedframe to that which was recovered.
d) an identical CEFAS smartbuoy to that which was recovered
e) Collect 10 vertical zooplankton net hauls (CEFAS).

2. At Site B 53 27 N 3 38.6 W, (CTD station 21)
To recover
a) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring. Attached to the mooring wire are Sea-Bird MicroCat temperature, conductivity loggers at 5 and 10m below the surface and miniloggers at 7.5 and 15 m below the surface.
b) A sea bed frame for a 600 kHz ADCP (waves ADCP) to measure the mean current profile, pressures and directional waves. A Sea-Bird SBE 16plus with pumped conductivity sensor, digiquartz pressure sensor and a SeaPoint turbidity sensor were fitted to the frame. A 1200 kHz telemetry ADCP was fitted to the frame.
c) A telemetry buoy.

f) A telemetry buoy fitted with an ACS and Sea-Bird MicroCat.

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. To obtain calibration samples for salinity, transmittance, suspended sediment and for chlorophyll at selected stations. To obtain near surface and bed water samples for nutrient and suspended sediment determination.

4. Collect sediment samples at each of the CTD sites.

5. Collect near surface water samples for Elena Stoica at stations 1, 21 & the most offshore station. Some of these samples are to be 'fixed' using provided formaldehyde solutions and frozen at -20C and others left in the fridge.

6. To conduct a benthic survey at site 1 and site 21 (five grab samples at each site).
