PurposeResearch
ObjectivesObjectives

1. At Site A 53 32 N 3 21.8 W, (Observatory CTD station 1 and 9)

To recover
a) A sea bed frame containing:
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.
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 VEMCO thermistor miniloggers at 7.5 and 15 m below the surface.

To deploy
an identical bedframe to that which was recovered.
an identical CEFAS smartbuoy to that which was recovered

e) Collect 10 vertical zooplankton net hauls (CEFAS).

2. At Site B 53 27N 3 38.6W (Observatory 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 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.

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.
