Parasites of the genus Ellobiopsis and epibiontic ciliates of the genus Paracineta were found on the body surface of some copepod taxa collected in the Kongsfjorden area (west Spitsbergen, Svalbard) during summer 2002. Paracineta sp. individuals were noted in Metridia longa and Paraeuchaeta norvegica (0.5% of the population infected in each species). This study provides the first record of the presence of Paracineta sp. in the latter species. Remarkably, epibionts were attached exclusively to females. Calanus finmarchicus and C. glacialis were invaded by Ellobiopsis spp., but the level of infection was generally low (0.06% and 0.09% of the population infected, respectively). Parasite distribution within both host populations was similar – 80% of infected specimens were at copepodid stage V. This study also provides the first record of C. glacialis serving as a host to Ellobiopsis.

Zooplankton was investigated at fixed site in 24 hours in Kongsfjorden, a glacial fjord situated on the west coast of Spitsbergen (Svalbard) (79°N, 12°E), in order to unveil the level of diurnal variability in community composition and abundance. Parallel to zooplankton study water temperature and salinity were measured while information on local tides and winds was obtained from external sources. Observed changes did not exceed the range of variability regarded intrinsic, resulting from the nature of plankton. Because of this low variability we are of the opinion that the data presented can be regarded a valid measure of the natural heterogeneity of zooplankton communities in hydrologically dynamic Arctic coastal waters in summer. The observed changes in zooplankton were primarily induced by the complex dynamics of the fjord's water masses. In spite of importance of tidal forcing, the variability in zooplankton did not demonstrate similar temporal fluctuations due to modification of the water movement by other irregular forces (local wind). Also, we have not found any indication of diel vertical migration in coastal water in the Arctic under the condition of midnight sun.
