Distribution of zooplankton in the Indian sector of the Southern Ocean
Abstract The community composition of zooplankton with an emphasis on copepods was assessed in the frontal zones of the Indian sector of the Southern Ocean (SO) during summer 2013. Copepods were the dominant group in both the bongo net and multiple plankton sampler across the entire region. High zoo...

Abstract The community composition of zooplankton with an emphasis on copepods was assessed in the frontal zones of the Indian sector of the Southern Ocean (SO) during summer 2013. Copepods were the dominant group in both the bongo net and multiple plankton sampler across the entire region. High zooplankton abundance was recorded along each transect in the Polar Front (PF). Community structure in this front was dominated by common taxa, including Ctenocalanus citer , Clausocalanus spp., Calanoides acutus , Calanus propinquus , Calanus australis and Rhincalanus gigas , which together accounted for > 62% of the total abundance.
