These samples were loaned to Cefas by ICES WGMEGS participating nations that collected the samples. The dataset consists of 551 samples split across 6 different time periods with a total of 59,160 eggs of which 45,721 identified to 30 different taxa and 78,067 larvae of which 69,894 were identified to 72 different taxonomic groups. Within the data set the date and time is recorded along with the latitude and longitude position. For each entry at maximum depth the profiler reached and the total volume of seawater filtered (m3), calculated by flowmeters, is recorded for each record.
