At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the
Arctic Ocean takes up carbon dioxide (CO 2) on the order of− 66 to− 199 Tg C year− 1 (10 …

ABSTRACT The Arctic Ocean is a potentially important sink for atmospheric carbon dioxide
(CO₂) with a recent estimate suggesting that the region contributes from 5 to 14% of the …

Climatic changes in the Northern Hemisphere have led to remarkable environmental
changes in the Arctic Ocean, which is surrounded by permafrost. These changes include …

The Arctic Ocean and adjacent continental shelf seas such as the Chukchi and Beaufort
Seas are particularly sensitive to long‐term change and low‐frequency modes of …

Less than three decades ago only a small fraction of the Arctic Ocean (AO) was ice free and
then only for short periods. The ice cover kept sea surface pCO2 at levels lower relative to …

The current downturn of the arctic cryosphere, such as the strong loss of sea ice, melting of
ice sheets and glaciers, and permafrost thaw, affects the marine and terrestrial carbon cycles …

Because of its ice cover the central Arctic Ocean has not been considered as a sink of
atmospheric carbon dioxide. With recent observations of decreasing ice cover there is the …

Rapid climate warming and sea-ice loss have induced major changes in the sea surface
partial pressure of CO2 (p CO 2). However, the long-term trends in the western Arctic Ocean …

Calcium carbonate (CaCO3) mineral saturation states for aragonite (Ωaragonite) and calcite
(Ωcalcite) are calculated for waters of the Chukchi Sea shelf and Canada Basin of the …

The polar oceans are particularly vulnerable to ocean acidification; the lowering of seawater
pH and carbonate mineral saturation states due to uptake of atmospheric carbon dioxide …
