Objectives

1.1 At site A, 53° 32′ N, 3° 21.8′ W (CTD station 1)
To recover:
a) A seabed frame containing a 600 kHz RDI ADCP (waves ADCP), SeaBird SBE 16plus, digiquartz pressure sensor, SeaPoint turbidity sensor with wiper; a SeaBird SBE 16plus with an Aanderra oxygen Optode and FSI conductivity, temperature logger.
b) CEFAS SmartBuoy in a single point mooring. Attached to the mooring wire are SeaBird MicroCat temperature, conductivity loggers at 5 m and 10 m below the surface and temperature miniloggers at 7.5 m and 15 m below the surface. Also attached was a Contros pCO2 instrument.
To deploy:
a) A seabed frame containing a 600 kHz RDI ADCP (measuring mean current profile, pressures and directional waves), SeaBird SBE 16plus (with pumped conductivity sensor), digiquartz pressure sensor, a SeaPoint turbidity sensor with wiper and SeaBird SBE 16plus (with an Aanderra oxygen Optode).
b) CEFAS SmartBuoy in a single point mooring. Attached to the mooring wire are SeaBird MicroCat temperature, conductivity loggers at 5 m and 10 m below the surface and temperature miniloggers at 7.5 m and 15 m below the surface. Plus a new WetLabs ACS unit and frame at 5m. To collect ten vertical zooplankton hauls for CEFAS.

1.2 At 'new' site B, 53° 32.3′ N, 3° 38.4′ W (CTD station 20)
To recover:
a) A seabed frame containing a 600 kHz RDI ADCP, a SeaBird SBE 16plus, digiquartz pressure sensor and a SeaPoint turbidity sensor fitted with a wiper.
b) A CEFAS SmartBuoy in a single point mooring. Attached to the mooring wire are SeaBird MicroCat temperature, conductivity loggers at 5 m and 10 m below the surface and temperature miniloggers at 7.5 m and 15 m below the surface.
To deploy:
a) A seabed frame for a 600 kHz RDI ADCP measuring mean current profile, pressures and directional waves; a SeaBird SBE 16plus (with pumped conductivity sensor), digiquartz pressure sensor and a SeaPoint turbidity sensor (fitted with a wiper).
b) A CEFAS SmartBuoy in a single point mooring. Attached to the mooring wire are SeaBird MicroCat temperature, conductivity loggers at 5 m and 10 m below the surface and temperature miniloggers at 7.5 m, 15 m and 20 m below the surface.

1.3 CTD and LISST survey
To conduct a CTD survey including LISST measurements at 34 sites every five nautical miles covering the eastern Irish Sea to determine the effects of the rivers Dee, Mersey and Ribble on Liverpool Bay. The survey covers the area from the coast of North Wales to a line extending westwards from Blackpool, and from the Lancashire coast to a line extending northwards from Great Ormes Head.
To obtain calibration samples for salinity, transmittance and suspended sediment at selected stations. To obtain near surface and bed water samples for nutrient (nitrate, phosphate, silicate) and suspended sediment determination. To obtain surface samples for a Defra pH/Alkalinity study by David Hydes (NOC, at Southampton). NOC Liverpool has supplied filtering equipment and filters for determining concentrations of suspended sediment and chlorophyll-a. CDOM samples will be obtained at some sites.

1.4 Other activities
Collect sediment samples at each CTD site with a Day grab for Andy Plater (University of Liverpool) and Ken Pye (Royal Holloway College). Ken Pye's samples were taken at sites that were missed on the previous cruise.

A pCO2 instrument was installed prior to the survey.

Collect samples for trace metal analysis, for in situ analysis and lab analysis.
