Agree – Disagree: Comparing Traffic Limitations in the Kara Sea
(Chapter, 2021)This study investigates variability of ships’ operational limitations for ice conditions in view of national rules and international recommendations (the Rules for Navigation in the Water Area of the Northern Sea Route and ... -
Barents Sea Oil and Gas 2025: Three Scenarios
(Chapter, 2015) -
Consolidation of fresh ice ridges for different scales
(Peer reviewed; Journal article, 2020)This study characterizes the refreezing process of deformed ice. Twenty laboratory experiments in ice ridge consolidation were conducted to study the influence of ridge blocks size, initial temperature, and top surface ... -
Different mechanisms of Arctic first-year sea-ice ridge consolidation observed during the MOSAiC expedition
(Peer reviewed; Journal article, 2023)Sea-ice ridges constitute a large fraction of the ice volume in the Arctic Ocean, yet we know little about the evolution of these ice masses. Here we examine the thermal and morphological evolution of an Arctic first-year ... -
Location of studies and evidence of effects of herbivory on Arctic vegetation: a systematic map
(Peer reviewed; Journal article, 2021)Herbivores modify the structure and function of tundra ecosystems. Understanding their impacts is necessary to assess the responses of these ecosystems to ongoing environmental changes. However, the effects of herbivores ... -
Predicting vessel speed in the Arctic without knowing ice conditions using AIS data and decision trees
(Peer reviewed; Journal article, 2021)The vessel speed is one of the important parameters that govern safety, emergency, and transport planning in the Arctic. While previous studies have traditionally relied on physics-based simulations to predict vessel's ... -
Quantifying false bottoms and under-ice meltwater layers beneath Arctic summer sea ice with fine-scale observations
(Peer reviewed; Journal article, 2022)Kartlegging av ferskvannslag og dannelse av falsk bunnis under sjøisen ved sommarsmelting i sentrale Polhavet Sjøisen i Polhavet er i rask endring. Den er blitt mye tynnere i løpet av de siste tiårene, havet og atmosfæren ... -
A risk assessment review of mercury exposure in Arctic marine and terrestrial mammals
(Peer reviewed; Journal article, 2022)There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) ... -
Sea or summit? Wild reindeer spatial responses to changing high-arctic winters
(Peer reviewed; Journal article, 2021)Because of climate change, wildlife is facing altered environments, including profound shifts in temperature and precipitation regimes. In snow-dominated ecosystems, winter warming and resulting changes in snowpack properties ... -
Supplementing remote sensing of ice: Deep learning-based image segmentation system for automatic detection and localization of sea ice formations from close-range optical images
(Peer reviewed; Journal article, 2021)This paper presents a three-stage approach for the automated analysis of close-range optical images containing ice objects. The proposed system is based on an ensemble of deep learning models and conditional random field ...
