| Abstract: | The distributions and abundances of copepod and barnacle naupliiare described along a five-station transect in the Irish Seafrom Liverpool Bay, England, to Dundalk Bay, Ireland, in May1989. Correspondence analysis revealed that various hydrographicregions in the Irish Sea are characterized by distinct naupliusassemblages. Acartia, Centropages and Temora nauplii were associatedwith the Welsh coastal water east of the Liverpool Bay front.The western stratified water to the west of the seasonal, westernIrish Sea front was distinguished from the mixed water to theeast by abundances of Calanus, Pseudocalanus, Oithona, Microcalanusand harpacticoid nauplii. The Liverpool Bay and western IrishSea fronts are, apparently, boundaries between coastal and offshoreassemblages of crustacean nauplii. |
