Abstract Although sea-ice ridges are prominent features of the Arctic Ocean, very little is known about their role as habitats and in biogeochemical cycles. Here, we show that ridges provide complex sea-ice habitats whic...

Abstract The observed decline of sea ice in the Arctic, if it persists into the future, can create more favorable conditions for shipping activity in the region. To estimate possible changes in key sea ice characteristic...

Abstract Emission of anthropogenic greenhouse gases has resulted in greater Arctic warming compared to global warming, known as Arctic amplification (AA). From an energy‐balance perspective, the current Arctic climate ...

Abstract Through data analysis and numerical simulations, this study reveals the winter Arctic Warming Pattern (AWP), characterized by anticyclonic anomalies over the North Pacific and the Urals, which plays a pivotal ro...

Relevance. Fundamentally new infrastructure and production solutions implemented in the Arctic macroregion can subsequently be scaled both in the subarctic regions and in the country as a whole, which determines the impo...

The article presents the results of a comprehensive study of strategic directions for improving the quality of life of the population in the Arctic territories of the Republic of Karelia. The relevance of the research is...

Based on a geographical-administrative definition of the region, the theoretical assumptions of contemporary French structuralist geopolitics, cross-sectional data for 1990, 1995, 2000, 2005 and 2010 from the Updated Arc...

Abstract The Arctic Oscillation (AO) is the most significant mode of sea level pressure (SLP) anomalies in the Northern Hemisphere, exhibiting significant multiple‐timescale variability from synoptic to decadal. Using ...

Abstract The crab-eating raccoon (Procyon cancrivorus) is a wild carnivore with a broad geographic distribution, randing from Costa Rica to South America. This species remains understudied, particularly regarding Sarcocy...

Muskox (Ovibos moschatus, Zimmermann 1780), or Umingmak (in Inuktitut), is a critical component of the terrestrial Arctic ecosystem. In many regions, muskoxen are key to Inuit food security and important to cultural iden...

The Alaskan tussock tundra is a strongly nutrient-limited ecosystem, where almost all vascular plant species are mycorrhizal. We established a long-term removal experiment to document effects of arctic plant species on e...

Three digestibility experiments on Arctic foxes were carried out. Control groups were fed standard diets (C1 and C2) composed of fresh or frozen animal by-products and steamed ground grain. Dry experimental diets (E1 and...

Abstract The Arctic is warming faster than any other region on Earth. This warming affects Arctic clouds, both directly and through changes in aerosol concentrations, triggering feedbacks that may further amplify the war...

Abstract We construct a linear model of microseism power as a function of sea‐ice concentration and ocean‐wave activity with a seismic station located on northern Ellesmere Island. The influence of wind‐ice‐ocean...

Increased focus on secure communications has created a growing interest in national and regional satellite systems. An elliptic medium earth orbit satellite system for Nordic/Arctic areas is proposed and investigated. Th...
