The influence of advection on zooplankton community composition in an Arctic fjord (Kongsfjorden, Svalbard).
A continuous, high-resolution time series of zooplankton and hydrographic data were collected from Kongsfjorden between April and September 2002 using a sediment trap and instrumentation deployed on a mooring. The time series has, for the first time, demonstrated the close relationship between water...

A continuous, high-resolution time series of zooplankton and hydrographic data were collected from Kongsfjorden between April and September 2002 using a sediment trap and instrumentation deployed on a mooring. The time series has, for the first time, demonstrated the close relationship between water mass advection and changes in zooplankton community structure in Kongsfjorden. Zooplankton identified in the trap samples included 31 species/genera and seven higher taxa representing ubiquitous, boreal and Arctic biogeographic origins. Correspondence Analysis (CA) identified three phases of zooplankton community composition in 2002. Phase I, from 18 April to 29 May, consisted primarily of resident Calanus finmarchicus and Calanus glacialis stage CVI females. Phase 11, from 30 May to 23 June, was dominated by meroplankton, Oikopleura cf. vanhoeffeni, C. finmarchicus early life stages (CI to CIII), Calanus hyperboreus and Themisto abyssorum.
