ObjectivesObjectives

1. Site A, 53° 32′ N, 3° 21.8′ W (CTD station 1)
To recover:
a)A sea bed frame containing a 600 kHz RDI ADCP (acoustic Doppler current profiler, 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 Aanderaa oxygen Optode.
b)Cefas SmartBuoy in a single point mooring. A temperature mini-logger is attached to the mooring wire at 7.5 m below the surface and SeaBird MicroCAT temperature and conductivity loggers at 10 m and 15 m below the surface. A frame containing a WET Labs ac-s unit (measuring spectra of absorption and attenuation), WET Labs fluorometer and SeaBird MicroCAT is attached at 5 m below the surface.
To deploy:
c)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 Aanderaa oxygen Optode.
d)Cefas SmartBuoy (including a weather station system) in a single point mooring. SeaBird MicroCAT temperature and conductivity loggers are attached to the mooring wire at 10 m and 15 m below the surface together with a mini-logger at 7.5m. In addition, a frame containing a WET Labs ac-s unit, WET Labs fluorometer and SeaBird MicroCAT is attached at 5 m below the surface.

2. Undertake a CTD survey of up to 34 stations every five nautical miles covering the eastern Irish Sea.

3. Complete a 25-hour station at site A of half-hourly conductivity, temperature and depth (CTD) profiles.

4. Water samples were obtained during the CTD survey and 25-hour station for on-board determination of the electrochemically labile copper. Also at the 25-hour station an in situ sensor was deployed for analysis of electrochemically labile copper.

5. To recover a fast sample 5-beam ADCP which had been deployed at 53° 47.994′ N, 4° 00.291′ W, near to site 29, for a recent turbulence glider mission.

6. Ten vertical zooplankton net hauls are to be collected at Site A to determine species diversity and abundance.
