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.

Measurements 
Physical oceanography 
Water bottle stationsQuantity: number of recoveries = 1
Description: DARD offshore mooring was serviced and samples taken.
Water bottle 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.
