Svalbard is a High Arctic Archipelago at 74–81°N and 15–35 °E under the sovereignty of Norway. All settlements in Svalbard, including the capital of Longyearbyen (population 2400), currently have isolated energy systems with coal or diesel as t

The Arctic plays a key role in understanding and mitigating the challenge of climate adaptation. Indeed, the observed Arctic warming is more than twice the global mean, implying that the Arctic may serve as an ‘early warning region’ in terms of c

It is frequently observed that long cracks in sea-ice tend to form between parallel channels during ice management operations. The long cracks that develop play an important role in reducing the size of the managed ice floes, which is one of the main

On the decay of first-year ice ridges: Measurements and evolution of rubble macroporosity, ridge drilling resistance and consolidated layer strength

In this study, four first-year ice ridges (R1, R2, R3 and R4) were measured during the transition from the “main” phase to the “decay” phase. The measurements were conducted on two ice floes in the Arctic Ocean northwest of Svalbard during Ma

The consolidation of saline ice blocks in water of varying freezing points: Laboratory experiments and computer simulations

Publikováno v: Cold Regions Science and Technology. 122:71-79

The thermodynamic consolidation of ice rubble in the ridge keel is an important mechanism both in global heat balance and when it comes to offshore structure interaction. Classically, it is considered that consolidation in the keel occurs due to rese
