Sinking in Slowly As the Arctic warms and its sea ice continues to melt, more of the ocean surface will be exposed, creating the potential for greater uptake of carbon dioxide from the atmosphere. Cai et al. (p. 556, published online 22 July) present results from a series of Arctic Ocean transects that show that the amount of CO2 in the surface waters has increased greatly recently. This will act as a barrier to future CO2 uptake and suggests that the Arctic Ocean will not become the large CO2… Expand

Further observations of a decreasing atmospheric CO2 uptake capacity in the Canada Basin (Arctic Ocean) due to sea ice loss
[1] Using data collected in 2009, we evaluated the potential for the southeastern Canada Basin (Arctic Ocean) to act as an atmospheric CO2 sink under the summertime ice-free conditions expected inExpand
Carbon Biogeochemistry of the Western Arctic: Primary Production, Carbon Export and the Controls on Ocean Acidification
The Arctic Ocean is an important sink for atmospheric carbon dioxide (CO2) with a recent estimate suggesting that the region accounts for as much as 15 % of the global uptake of CO2. The westernExpand
Distributions and air–sea fluxes of carbon dioxide in the Western Arctic Ocean
Abstract The uptake of carbon dioxide (CO2) by the Arctic Ocean is most likely increasing because of the rapid sea-ice retreat that lifted the barriers preventing gas exchange and light penetrationExpand
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 beExpand
Changes in the Arctic Ocean Carbon Cycle With Diminishing Ice Cover
TLDR
It is suggested that increased ice‐free periods will further increase sea surface pCO2, reducing the Canada Basin's current role as a net sink of atmospheric CO2. Expand
Effects of ocean acidification, warming and melting of sea ice on aragonite saturation of the Canada Basin surface water
[1] In 2008, surface waters in the Canada Basin of the Arctic Ocean were found to be undersaturated with respect to aragonite. This is associated with recent extensive melting of sea ice in thisExpand
Carbon Fluxes Across Boundaries in the Pacific Arctic Region in a Changing Environment
While the inflow of dissolved inorganic carbon (DIC) from the Pacific Ocean is relatively well quantified, the intermittent input from the East Siberian Sea (ESS) is not. The export flux to theExpand
Controlling factors analysis of pCO2 distribution in the Western Arctic Ocean in summertime
The uptake of carbon dioxide (CO2) by the Arctic Ocean has been changing because of the rapid sea-ice retreat with global warming. The Chukchi Sea is the only gateway of the warm and nutrient-richExpand
Tracing environmental variability in the changing Arctic Ocean with optical measurements of dissolved organic matter.
The Arctic Ocean plays an important role on the global hydrological and carbon cycles. It contributes 5–14% to the global balance of CO2 sinks and sources. Carbon is also cycled in the Arctic OceanExpand
Increase in acidifying water in the western Arctic Ocean
Ocean acidification has expanded in the western Arctic Ocean. Observations from the 1990s to 2010 show that aragonite saturation levels have decreased, with low saturation water deepening to 250 mExpand

TLDR
The increase in anthropogenic carbon dioxide emissions and attendant increase in ocean acidification and sea ice melt act together to decrease the saturation state of calcium carbonate in the Canada Basin of the Arctic Ocean. Expand
