ObjectivesThe cruise was the fourth of five plankton surveys in 2010 to estimate the Spawning Stock Biomass (SSB) of plaice, cod and haddock in the Irish Sea by the Annual Egg Production Method (AEPM). These cruises are basically a repeat of a similar series of surveys conducted in 2008.

In addition to plankton sampling at 106 pre-selected stations, various supplementary data was obtained ranging from environmental data to acoustics.
