Description: Diel Vertical Migration which is known to be a common behavior in zooplankton and fish in temperate areas was so far considered to be of minor importance in high Arctic ecosystems. We carried out investigations of two fjord ecosystems on northern Svalbard (Kongsfjorden and Rijpfjorden, 79° and 80ºN) as well as two stations in the MYI north from Svalbard at 82°N in September 2004. Acoustics was applied to look for diurnal changes in vertical distribution patterns of pelagic organisms. In addition, we carried out an extensive biological sampling program.
