Kongsfjorden is a glacial fjord in the Arctic (Svalbard) that influenced by both Atlantic and water masses harbours mixture of boreal flora fauna. Inputs from large tidal glaciers create steep environmental gradients sedimentation salinity along length this fjord. The inputs cause reduced biomass diversity benthic community inner Zooplankton suffers direct mortality outflow primary production because limited light levels turbid, mixed waters. magnitude effects diminishes towards outer an...
Abstract The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to thinner and largely seasonal first-year with significant consequences for primary production. One critical challenge understand how productivity will change within the next decades. Recent studies have reported extensive phytoplankton blooms beneath ponded sea during summer, indicating that satellite-based annual production estimates may be significantly underestimated. Here we present unique...
The distribution of Calanus species was investigated in Kongsfjorden summer 1996 and 1997. In both years finmarchicus glacialis dominated, although the boreal C. more abundant than Arctic This coincided with a 2°C higher water temperature at 50 m 1997, indicating stronger influence Atlantic origin that year. Advected occurred deep subsurface layers outer fjord (200 ind. m−3, mainly CIII). A less local population aggregated surface inner (100 m−3). Similarly, advected 1997 (446 CIII CIV) (183...
The largest contribution of oceanic heat to the Arctic Ocean is warm Atlantic Water (AW) inflow through deep Fram Strait. AW current also carries plankton into Basin and this zooplankton biomass Atlantic-Arctic gateway far exceeds shallow Pacific-Arctic gateway. However, because transport has not yet been adequately quantified based on observational data, so that present poorly defined, future changes in communities are difficult project observe. Our objective was quantify Strait during...
Seasonal plankton time-series data are presented from Kongsfjorden two years with contrasting environmental conditions. (west coast of Spitsbergen – 79°N) integrates inputs Atlantic and Arctic waters, glacier run-off, is thus a prime location to study impacts on ecosystem dynamics key drivers that relevant across the Arctic. Despite extensive research in Kongsfjorden, seasonally-resolved scarce. From late April/early May early September 2019 2020, we conducted pelagic sampling at mid-fjord...

Seasonal changes in the zooplankton composition of glacially influenced Kongsfjorden, Svalbard (79°N, 12°E), and its adjacent shelf were studied 2002. Samples collected spring, summer autumn stratified hauls (according to hydrographic characteristics), by means a 0.180-mm Multi Plankton Sampler. A strong front between open sea fjord waters was observed during preventing water mass exchange, but not later season. The considerable seasonal abundance related variation hydrographical regime....

Abstract Copepods of the genus Calanus play a key role in marine food webs as consumers primary producers and prey for many commercially important species. Within genus, glacialis finmarchicus are considered indicator species Arctic Atlantic waters, respectively, changes their distributions frequently used tool to track climate change effects ecosystems northern hemisphere. Despite extensive literature available, discrimination between these two remains challenging. Using genetically...
Diel vertical migration (DVM) of zooplankton is a global phenomenon, characteristic both marine and limnic environments. At high latitudes, patterns DVM have been documented, but rather little knowledge exists regarding which species perform this ecologically important behaviour. Also, in the Arctic, vertically migrating components community are usually regarded as single sound scattering layer (SSL) performing synchronized directly controlled by ambient light. Here, we present evidence for...
Planktonic copepods of the genus Calanus play a central role in North Atlantic/Arctic marine food webs. Here, using molecular markers, we redrew distributional ranges species inhabiting Atlantic and Arctic Oceans revealed much wider more broadly overlapping distributions than previously described. The shelf species, C. glacialis , dominated zooplankton assemblage many Norwegian fjords, where only finmarchicus has been reported previously. In these high occurrences hyperboreus were also...
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 Barents Sea is undergoing rapid ocean warming with less sea ice and increased Atlantic inflow, shifting the pelagic ecosystem towards a more boreal one, process referred to as Atlantification. While such changes have already been documented in southern central Sea, known about degree of Atlantification northern Arctic Ocean. In this seasonal study, we identified mesozooplankton biodiversity, abundance biomass Northern along transect seven stations stretching from (76°N) across shelf...
