(2022-04-19)It is estimated that the Arctic contains half of the global soil carbon pool, and climate warming will lead to considerable degradation of permafrost. This degradation may lead to the expansion or drainage of Arctic ...
-
(2016-08-26)In mid-nineteenth century Britain, the dramatic disappearance of Sir John Franklin and his men led to a large-scale search conducted throughout the Arctic by sailing ships and steamers. One such ship was HMS Pioneer (formerly ...
-
(2014-04-25)Understanding the climatic drivers of changes in sea ice extent in the Arctic has become increasingly important as record minima in the September sea ice extent continue to be reached. This research therefore addresses the ...
-
(2014-07-30)Shrub expansion is one of the most recognized components of terrestrial Arctic change and has been documented in studies involving fine-scale experimental manipulations or broad-scale satellite remote sensing. The ...
-
(2014-06-24)The Arctic is a unique and complex environment. Many factors play a role in determining the long-term climate of the Arctic, including mesoscale weather systems and many complex ice-albedo feedback mechanisms. Previous ...
-
(2012-04-16)In the past decade there has been an overall decrease in Arctic Ocean sea ice cover. Changes to the ice cover have important consequences for organic carbon cycling, especially over the continental shelves. When sea ice ...
-
(2019-04-02)Species distributions are expected to shift with changes in climate at a global scale. The northern latitudes are warming at a rate three times greater than the global mean, which has resulted in the Arctic tundra undergoing ...
-
(John Wiley and Sons, Inc., 2015)Recent increases in deciduous shrub cover are a primary focus of terrestrial Arctic research. This study examined the historic spatial patterns of shrub expansion on the North Slope of Alaska to determine the potential ...
-
(2021-03-24)Increasing temperatures have been altering hydrological conditions and leading to ecological regime shifts across the Arctic biome, with influences on terrestrial carbon cycling. However, the sign, extent, and magnitude ...
-
(2021-04-16)Rising global temperatures are a threat to Arctic ecosystems. Thawing permafrost is expected to expose previously frozen carbon to microbial decomposition, an action that will promote further warming and have consequences ...
-
(2014-06-02)Changing climatic conditions and shifting global economics have thrust the Arctic into the spotlight for many scientists, academics, and policymakers as well as those in offshore industries, particularly in shipping and ...
