Distribution and Adaptations of Sea Ice Inhabiting Harpacticoida (Crustacea, Copepoda) of the Weddell Sea (Antarctica)
Abstract. Seven harpacticoid species were found to be associated with sea ice collected during 5 Antarctic cruises of the RV Polarstern. Their distribution within the fast ice and pack ice zones of the Weddell Sea is presented. Whereas some individuals probably become entrapped into the ice only acc...
