Economic theory and development planning in the Arctic regions: A study in plural economy
This is a paper on economic method and strategy, in which the aim is to apply economic theory to the task of practical development planning in a peripheral regional economy. This is done in the form of a case study on the Northwest Territories (NWT), Canada. There are four main sections. First, the …

Durability of Cementitious Materials in Arctic Regions: Investigating Freeze-Thaw Damage and Chloride Ingress Diffusion Mechanisms
Concrete infrastructure in the Arctic coastal region faces durability challenges from freeze-thaw (F-T) cycles and chloride ingress due to seawater and deicing salts, resulting in surface scaling, spalling, and cracking. Climate change exacerbates these issues, particularly in high-latitude areas …

Ice Island Deterioration in the Canadian Arctic: Rates, Patterns and Model Evaluation
… as ice islands, is limited within the Canadian Arctic. This study analyzed ice island deterioration through two aspects: 1) horizontal (areal) and 2) vertical (surface melt or ‘ablation’). Satellite images were digitized to monitor areal dimensions, classify deterioration modes and correlate …

Wrangell Island: From political conflict to Russian sovereignty
… qualify as the first World Heritage Site in the Arctic regions. This designation would permit Russia to advance Arctic conservation achievements, thus allowing Wrangell Island and Herald Island to assume an important place comparable with other World Heritage Site islands such as the Galapagos, …

Crustacea Zooplankton Communities in Icelandic Lakes Comparison Over Time
… trophic levels. Monitoring biodiversity in Arctic and sub-Arctic regions is particularly important given ongoing rapid climate change. Communities were compared using data from two national surveys: the Ecological Survey of Icelandic Lakes (1992–1998) and the Natura Project (2012–2013). …

Observing Seasonal Cycles in Greenhouse Gas Fluxes with Automatic Flushing Chambers in a Low-Arctic Lake
The Arctic is warming nearly four times faster than the global average. Greenhouse gases (GHG) are causing a changing climate which is affecting permafrost thaw, sea ice melt, and changing hydrological dynamics. Lakes in the Arctic and sub-Arctic regions are increasingly recognised as important …

Integrated Terrestrial and Hydrological Carbon Budgets in High Arctic Watersheds
… is important for informing climate models. High Arctic regions are particularly key areas for carbon cycle research because they are understudied relative to other regions, and because accelerated climate change is altering many processes affecting carbon fluxes, with the net effect of these …

Analysis of microtopography, vegetation, and active-layer thickness using terrestrial LIDAR and kite photography, Barrow, AK
Arctic regions underlain by permafrost are among the most vulnerable to impacts from climate change. This study examined changes in the active layer of permafrost near Barrow, Alaska at very fine scale to capture subtle changes related to microtopography and landcover. In 2010, terrestrial LIDAR …

Oceanic Light Absorption Properties: Assessment and Characterization in the Southeastern Bering Sea Using Field and Satellite Observations
… remotely measured optical parameters of sub-arctic regions required for an improved understanding of biological responses to climatic forcing.

A multi-scaled approach to vegetation and landscape assessment in the Barents region: Reindeer habitat in a climate of change
The circumpolar Arctic is predicted to be particularly affected by global change, including climate change. Likely ecological vulnerabilities include flora and dependent fauna. Reindeer (Rangifer tarandus), a keystone Arctic herbivore, are of particular importance, ecologically, as well as …

Assessing the potential for renewable energy systems in remote arctic communities as a means of reducing regional diesel fuel dependence
The Arctic region faces many challenges related to combating the effects of climate change. Research has suggested that the region is overall more impacted by the rise in greenhouse gas emissions than other regions on Earth. More remote Arctic communities are dependent on fossil fuel sources, such …

Network of Conflicts : The obscure legal framework of the Sámi in the Kola Peninsula, Northwest Russia
… attitude of the Russian Federation towards its Arctic regions manifests itself in the primacy of the capitalist benefit of the Kola Peninsula at the expense of the rights and traditions of the Kola Sámi. The results show that during V. V Putin’s current administration, the nature of the rights …

A Unified Model for Multi-Phase Flow and Heat Transfer in Wellbores
… is important in many production operations in arctic regions. A prior knowledge of the temperature and pressure profile enables the operators to take preventive measures against the clogging of pipelines due to hydrate or wax formation. Accurate temperature estimation is also important during …

Numerical modelling of the dynamics response of glacier to changing climates
… at high latitudes. Wetter conditions in these regions are quite plausible with global warming due to warmer sea surface temperatures, melting of sea ice and a greater moisture holding capacity of the atmosphere. Recent observations show a marked increase in precipitation in the High Arctic …

The seasonal dynamics of Arctic surface hydrology in permafrost environments
… and hydrologi- cal cycling. In the Arctic and sub-Arctic permafrost zones, rising air temperatures are warming, and in some regions even thawing, the frozen ground. Permafrost is a carbon sink. The thermal state of the ground therefore has important implications on carbon exchange …

The influence of heat transport on Arctic amplification
The Arctic surface air temperature has warmed nearly twice as much as the global mean since the mid-20th century. Arctic sea ice has also been declining rapidly in recent decades. There is still discussion about how much of this Arctic amplification is caused by local factors, such as changes in …
