Glacial lake outburst floods (GLOFs) significantly affect downstream communities in Alaska. Notably, GLOFs originating from Suicide Basin, adjacent to Mendenhall Glacier, have impacted populated areas in Juneau, Alaska since 2011. On the Kenai Peninsula, records of GLOFs from Snow Glacier date as far back as 1949, affecting downstream communities and infrastructure along the Kenai and Snow river ...

Infrastructure systems, such as wind farms, are prone to various human-induced and natural disruptions such as extreme weather conditions. There is growing concern among decision makers about the ability of wind farms to withstand and regain their performance when facing disruptions, in terms of resilience-enhanced strategies. This paper proposes a probabilistic model to calculate the resilience of ...

The article discusses China’s policies in and towards the Arctic and Africa within a comparative perspective. To what extent is China’s policy adaptable to different conditions? What does this adaptability tell us about China’s ascendant great-power role in the world in general? What is the message to the Arctic and Africa respectively? The article concludes that China’s regional strategies aptly ...

This study presents a deep learning framework to support regional ship behavior prediction using historical AIS data. The framework is meant to aid in proactive collision avoidance, in order to enhance the safety of maritime transportation systems. In this study, it is suggested to decompose the historical ship behavior in a given geographical region into clusters. Each cluster will contain trajectories ...

Unmanned Aerial Vehicles (UAV) technology has found its way into several civilian applications in the last 20 years, predominantly due to lower cost and tangible scientific improvements. In its application to structural bridge inspection, UAVs provide two main functions. The first, being the most common, detect damage through visual sensors. The 2 D image data can be used to quickly establish a basic ...

Longyearbyen has been hit by two avalanches in 2015 and 2017 causing severe damages to housing and two fatalities. In this study we investigate organised learning processes regarding emergency preparedness and response following the avalanches. Longyearbyen provides a case of particular interest as climatic change rapidly is altering the environmental conditions, including the risk of avalanches.< ...

The article is an analytical state-of-the-art review of the Russian Federation’s critical infrastructure policy, starting from the 1990s but zooming in on the current situation. The article discusses what does critical infrastructure mean in the Russian context. It explores the country’s threat scenarios in this field, and asks what part is played by cyber security threats in this context. Further, ...

The Arctic is frequently framed as a region of disaster and conflict, as well as of opportunity and cooperation. Disaster diplomacy is one approach for examining how dealing with disasters might or might not affect conflict and cooperation, yet little work on Arctic disaster diplomacy has been completed, especially regarding specific bilateral relations. This paper contributes to filling in this gap ...

The time required for rescue is a critical factor for surviving a marine incident. The regulatory framework, International Maritime Organization (IMO) Polar Code, utilizes a risk-based approach. It states that the vessel operators are to define the time required for rescue but never less than 5 days. Based on experience from the classification society DNV GL, utilization of the minimum requirement ...
