Zooplankton abundance and community structures were studied in three west Spitsbergen fjords at the beginning of warm phase, which seem to have entered 2006. Sampling was conducted summer 2007 stations distributed along transects Hornsund, Isfjorden Kongsfjorden. Variations zooplankton standing stocks (assessing taxonomic diversity zoogeographical affiliations) analysed relation environmental variables using multivariate techniques. The hydrographic conditions Hornsund influenced by cold...

Atlantic water (AW) carries large amounts of salt, oceanic heat, and biological richness into the Arctic Ocean. The inflow AW has a two-branch structure via West Spitsbergen Current (WSC) in Fram Strait Barents Sea Opening (BSO), impact on Ocean ecosystem depends entrance route. Using data collected during summers 2001–2014, zooplankton standing stock community were studied these two branches. Generally, there was higher abundance biomass Calanus finmarchicus BSO than WSC, where Oithona spp....

The biomass of Calanus spp. in the Norwegian Atlantic Current and West Spitsbergen (2001–2009) was statistically related to a combination salinity, temperature, water depth sea ice concentration. aim this study identify significance these environmental factors for controlling species-specific distribution nature such relationships. finmarchicus dominated entire area its mainly salinity. glacialis found along northwest shelf Barents Sea, but also concentration temperature with critical...

Zooplankton inhabiting the Hornsund and Kongsfjorden fjords on Spitsbergen (Svalbard) were investigated in summer 2013. The goal of study was to determine how zooplankton communities vary environments functioning under different oceanographic regimes. Sampling conducted with nets mesh size selectivity (56 μm WP-2, 180 MultiNet, 1000 Tucker Trawl), which permitted comparing a wide spectrum components. Species composition did not differ substantially between fjords, but almost two times less...

Marine ecosystems in Arctic regions are expected to undergo large changes, driven by sea ice retreat and increasing influence of warmer saline waters. We examined changes the hydrography mesozooplankton from a 14-year long time series West Spitsbergen Current during summer period. The aim was provide contemporary description spatial temporal variations zooplankton community inhabiting surface layer (0-60 m), over an area extending 6 latitudinal degrees nearly 20 longitudinal degrees. A total...
