Objectives

Objectives

1.1 At site A, 53° 32′ N, 3° 21.8′ W
To recover:
a) A sea bed 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 a 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 Wetlabs fluorometer on a frame at 5m.
To deploy:
a) A sea bed 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 (including a new weather station system) in a single point mooring. Temperature mini-loggers are attached to the mooring wire at 7.5 m and 15 m below the surface and a SeaBird Microcat temperature and conductivity logger at 10m below the surface. A frame with a WetLabs ACS unit, Wetlabs fluorometer and SeaBird MicoCat is attached at 5m below the surface.

1.2 At 'new' site B, 53° 32.3′ N, 3° 38.4′ W (CTD station 20)
To recover:
a) A sea bed 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), suspended sediment and chlorophyll-a determination. NOC Liverpool has supplied filtering equipment and filters for determining concentrations of suspended
sediment and chlorophyll-a.
To test an OSIL YSI CastAway CTD system

1.4 Other activities
Sea bed sediment analysis. To collect sediment samples at each CTD site with a Day grab for Andy Plater (University of Liverpool).
Zooplankton net hauls: To collect 10 vertical zooplankton net hauls for CEFAS at Site A
