PurposeResearch
ObjectivesCEFAS charter. Third in a series of five plankton surveys in the eastern Irish Sea in 2003 to:
1) Determine plaice egg spawning and production.
2) Collect zooplankton samples for copepod production and fish larval feeding studies (not collected on this particular cruise).

Measurements 
Physical oceanography 
CTD stationsQuantity: number of stations = 49
Description: FSI mini-CTD attached to sampler frame to provide profile of conductivity, temperature and depth. Purpose to monitor/ provide information on environmental paramaters.
Subsurface temperature and salinity measurementsQuantity: number of stations = 16
Description: Samples of sea water from surface/nr surface collected during selected tows. Analysed ashore for conductivity to compare to CTD measurements.
Biology and fisheries 
ZooplanktonQuantity: number of stations = 49
Description: Samples collected using Gulf VII plankton sampler, towed from surface to near bottom in 'V' shaped profile. Volume of water filtered calculated from self-logging flow meters inside nose cone. Eggs and larvae collected in 270um mesh net and preserved in formalin for later analysis. Purpose of analysis - to identify and quantify eggs and larvae.
