Community Structure of Copepods Associated with Water Mass Replacement in the Coastal Area of the Southwestern Okhotsk Sea During Ice-free Period

Abstract

We investigated relationship between copepod community and seasonal change of water masses during 15 April-5 December 2013. Four seasonal copepod communities（spring/early-summer, summer, fall, and early-winter community）during the ice-fee period were clearly recognized by Bray-Curtis similarity analysis. Successional sequence of copepod community was corresponded with water mass replacement.
