Ziel der Reise / Objectives of Cruise:

This was the third, of five planned plankton surveys to estimate the spawning stock biomass (SSB) of cod, haddock and plaice in the Irish Sea using the annual egg production method (AEPM).\n1. To conduct a plankton survey using a 76cm Gulf VII plankton sampler to determine the distribution and abundance of cod (Gadus morhua), haddock (Melanogrammus aeglifinus) and plaice (Pleuronectes platessa) eggs.\n2. To remove fish eggs from fresh plankton samples at sea. To measure, stage and preserve these eggs in ethanol prior to species identification using a DNA technique on return to the laboratory.\n3. To collect surface nutrient and chlorophyll samples at each sampling station.\n4. To collect a surface phytoplankton and salinity sample every three sampling stations.\n5. To collect fine mesh (80 micron) PUP net samples for subsequent zooplankton analysis on every Gulf VII deployment.\n6. To continuously monitor sub-surface (3m) salinity, temperature and fluorometer data using the ships pumped seawater supply and onboard CTD.\n\n\n
