PurposeResearch
Objectives1. To service the DARD mooring in the western Irish Sea.
2. To investigate the near surface distribution of temperature, salinity and chlorophyll in the Irish Sea.
3. To investigate zooplankton abundance and species composition in relation to environmental variables in the Irish Sea.
4. To relate estimates of primary production to satellite imagery.
5. To undertake a preliminary study of the distribution of stable isotopes in the plankton and benthos in different regions of the Irish Sea.
6. To investigate the distribution of heavy metals associated with suspended particulate material.

Water bottle stationsQuantity: number of recoveries = 1
Description: DARD offshore mooring was serviced and samples taken.
CTD stationsQuantity: number of stations = 5
Description: A line of 5 stations was worked before sailing to Liverpool.
CTD stationsDescription: At DARD mooring site a CTD profile was recorded, water samples were taken for the calibration of the fluorometer and sediment samples for heavy metals.
Subsurface temperature and salinity measurementsDescription: Near surface temperature and sainity samples were taken at 1min intervals on transect across the Irish Sea. Duration of sample taking not specified.

Biology and fisheries 
Phytoplankton pigs (eg chlorophyll, fluorescence)Description: At DARD mooring site a CTD profile was recorded, water samples were taken for the calibration of the fluorometer and sediment samples for heavy metals.
Phytoplankton pigs (eg chlorophyll, fluorescence)Description: Near surface water samples were collected at 30 min intervals for estimation of chlorophyll and concentrations of dissolved inorganic nutrients. Duration of sampling not specified.
