Food for thought Phytoplankton abundances in the Arctic Ocean have been increasing over recent decades as the region has warmed and sea ice has disappeared. The presumptive causes of this increase were expanding open water area and a longer growing season—at least until now. Lewis et al. show that although these factors may have driven the productivity trends before, over the past decade, phytoplankton primary production rose by more than half because of increased phytoplankton concentrations… 
Freshening leads to a three-decade trend of declining nutrients in the western Arctic Ocean
Rapid warming and sea-ice loss in the Arctic Ocean are among the most profound climatic changes to have occurred in recent decades on Earth. Arctic Ocean biological production appears that it may be
Under-Ice Phytoplankton Blooms: Shedding Light on the “Invisible” Part of Arctic Primary Production
The growth of phytoplankton at high latitudes was generally thought to begin in open waters of the marginal ice zone once the highly reflective sea ice retreats in spring, solar elevation increases,
Phytoplankton dynamics in a changing Arctic Ocean
Changes in the Arctic atmosphere, cryosphere and Ocean are drastically altering the dynamics of phytoplankton, the base of marine ecosystems. This Review addresses four major complementary questions
Nutrient pathways and their susceptibility to past and future change in the Eurasian Arctic Ocean
How nutrient dynamics may continue to change, why this is important for regional and international policy-making and relevant research priorities for the future are highlighted are highlighted and suggested.
The Changing CO2 Sink in the Western Arctic Ocean From 1994 to 2019
The Arctic Ocean has turned from a perennial ice‐covered ocean into a seasonally ice‐free ocean in recent decades. Such a shift in the air‐ice‐sea interface has resulted in substantial changes in the
Processes controlling aggregate formation and distribution during the Arctic phytoplankton spring bloom in Baffin Bay
In the last decades, the Arctic Ocean has been affected by climate change, leading to alterations in the sea ice cover that influence the phytoplankton spring bloom, its associated food web, and
Rapid Acidification of the Arctic Chukchi Sea Waters Driven by Anthropogenic Forcing and Biological Carbon Recycling
The acidification of coastal waters is distinguished from the open ocean because of much stronger synergistic effects between anthropogenic forcing and local biogeochemical processes. However, ocean
Around one third of current Arctic Ocean primary production sustained by rivers and coastal erosion
It is suggested that nutrient input from the land is a key process that will affect the future evolution of Arctic Ocean NPP, and an ocean-biogeochemical model is used to estimate that this input fuels 28–51% of annual Arctic Ocean productivity.
. The physical system of the Arctic is changing in profound ways, with implications for the transport of nutrients to and from the Arctic Ocean as well as the internal cycling of material on shelves
Oceanographic and biogeochemical drivers cause divergent trends in the nitrogen isoscape in a changing Arctic Ocean
It is demonstrated that the canonical isotopic gradient between the Pacific and Atlantic sectors of the Arctic Ocean has grown to 3–4‰ and will continue to expand under a high emissions climate change scenario by the end of the twenty-first century.


Primary production in the Arctic Ocean, 1998–2006
[1] Sea ice in the Arctic Ocean has undergone an unprecedented reduction in area and thickness in the last decade, exposing an ever increasing fraction of the sea surface to solar radiation and
Faster Atlantic currents drive poleward expansion of temperate phytoplankton in the Arctic Ocean
The link between the poleward intrusion of the temperate coccolithophore Emiliania huxleyi and the North Atlantic current is revealed, showing evidence for bio-advection as an important mechanism and confirming the biological and physical “Atlantification” of the Arctic Ocean with potential alterations to the Arctic marine food web and biogeochemical cycles.
Are phytoplankton blooms occurring earlier in the Arctic?
Time series of satellite‐derived surface chlorophyll‐a concentration (Chl) in 1997–2009 were used to examine for trends in the timing of the annual phytoplankton bloom maximum. Significant trends
Influence of Phytoplankton Advection on the Productivity Along the Atlantic Water Inflow to the Arctic Ocean
Northwards flowing Atlantic waters transport heat, nutrients, and organic carbon in the form of zooplankton into the eastern Greenland Sea and Fram Strait. Less is known of the contribution of
Secular trends in Arctic Ocean net primary production
[1] A satellite-based study was conducted to document daily changes in net primary production (NPP) by phytoplankton in the Arctic Ocean from 1998 to 2009 using fields of sea ice extent, sea surface
Modeling the impact of declining sea ice on the Arctic marine planktonic ecosystem
[1] We have developed a coupled 3-D pan-Arctic biology/sea ice/ocean model to investigate the impact of declining Arctic sea ice on the marine planktonic ecosystem over 1988–2007. The biophysical
Arctic warming hotspot in the northern Barents Sea linked to declining sea-ice import
The Arctic has warmed dramatically in recent decades, with greatest temperature increases observed in the northern Barents Sea. The warming signatures are not constrained to the atmosphere, but
Increasing cloudiness in Arctic damps the increase in phytoplankton primary production due to sea ice receding
Abstract. The Arctic Ocean and its marginal seas are among the marine regions most affected by climate change. Here we present the results of a diagnostic model used to assess the primary production
