Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod. . 410 0$aAdvances in Polar Ecology,$x2468-5712 ;$v4 606 $aEcosystems 606 $aBiodiversity 606 $aAquatic ecology  606 $aClimate change 606 $aPolar regions 606 $aPlant biochemistry 606 $aEcosystems$3https://scigraph.springernature.com/ontologies/product-market-codes/L1904X 606 $aBiodiversity$3https://scigraph.springernature.com/ontologies/product-market-codes/L19031 606 $aFreshwater & Marine Ecology$3https://scigraph.springernature.com/ontologies/product-market-codes/L19066 606 $aClimate Change/Climate Change Impacts$3https://scigraph.springernature.com/ontologies/product-market-codes/313000 606 $aPolar Geography$3https://scigraph.springernature.com/ontologies/product-market-codes/J16020 606 $aPlant Biochemistry$3https://scigraph.springernature.com/ontologies/product-market-codes/L14021 606 $aEcologia marina$2thub 607 $aRegions polars$2thub 608 $aLlibres electrònics$2thub 615 0$aEcosystems. 615 0$aBiodiversity. 615 0$aAquatic ecology . 615 0$aClimate change. 615 0$aPolar regions. 615 0$aPlant biochemistry. 615 14$aEcosystems. 615 24$aBiodiversity. 615 24$aFreshwater & Marine Ecology. 615 24$aClimate Change/Climate Change Impacts. 615 24$aPolar Geography. 615 24$aPlant Biochemistry. 615 7$aEcologia marina 676 $a577.7 702 $aBerge$b Jørgen$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aJohnsen$b Geir$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aCohen$b Jonathan H$4edt$4http://id.loc.gov/vocabulary/relators/edt 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910409699703321 996 $aPOLAR NIGHT Marine Ecology$92528927 997 $aUNINA
