The measurement ofice thickness 158 The intermediate and deep currents in the Arctic Basin are much more difficultto measure, and appear to be quite different in sense from the surface currents. Fig.doi:10.1080/00222936708679718JeffreysJ. Gwyn...
In light of global change, this SLR could be a manifestation of warming in the Arctic coupled with a decrease of sea ice extent, warming of Atlantic waters, changes in the Arctic Ocean circulation, and an increase in coastal erosion and thawing of permafrost.We have analyzed monthly mean sea...

The volume, extent and age of Arctic sea ice is in decline, yet winter sea ice production appears to have been increasing, despite Arctic warming being most intense during winter. Previous work suggests that further warming will at some point lead to a decline in ice production, however a co...
Salinity-driven density stratification of the upper Arctic Ocean isolates sea-ice cover and cold, nutrient-poor surface waters from underlying warmer, nutrient-rich waters. Recently, stratification has strengthened in the western Arctic but has weakened

They predicted a further pH decrease at higher latitudes where sea ice retreat is active, highlighting the urgency to cut carbon emissions to preserve the Arctic ecosystem. "Ocean acidification can exert catastrophic impact on marine life like clam, mussel and conch, which are the staple for the...
The latter is a time interval when the high latitudes were significantly warmer than today. We document that even under such warmer climate conditions, sea ice existed in the central Arctic Ocean during summer, whereas sea ice was significantly reduced along the Barents Sea continental margin ...
