Field study of a direct absorption solar collector with eco-friendly nanofluid
(Peer reviewed; Journal article, 2024)The concept of direct absorption solar collector (DASC) was introduced in the 1970s. Multiple laboratory studies proved that nanofluid-based DASCs presented a fruitful alternative to conventional solar collectors. However, ... -
Study on Certification Criteria of Building Energy and Environmental Performance in the Context of Achieving Climate Neutrality
(Journal article, 2023)Increased greenhouse gas emissions have led to a global warming threat. As a result, countries have tended to focus their decision-making attention on energy-saving strategies. Specifically, the concept of green building ... -
Ice geometry and thermal regime of Lyngmarksbræen Ice Cap, West Greenland
(Peer reviewed; Journal article, 2023)Observations remain sparse for peripheral glaciers and ice caps in Greenland. Here, we present the results of a multi-frequency radar survey of Lyngmarksbræen Ice Cap in West Greenland conducted in April 2017. Radar ... -
Surge-type glaciers in Kalaallit Nunaat (Greenland): distribution, temporal patterns and climatic controls
(Peer reviewed; Journal article, 2023)We present the first systematic inventory of surge-type glaciers for the whole of Greenland compiled from published datasets and multitemporal satellite images and digital elevation models. The inventory allows us to define ... -
Saproxylic beetles' morphological traits and higher trophic guilds indicate boreal forest naturalness
(Peer reviewed; Journal article, 2023)Forests contribute to numerous ecosystem functions and services and contain a large proportion of terrestrial biodiversity, but they are being negatively impaced by anthropogenic activities. Forests that have never been ... -
Permafrost trapped natural gas in Svalbard, Norway
(Peer reviewed; Journal article, 2023)Permafrost is widespread in the High Arctic, including the Norwegian archipelago of Svalbard. The uppermost permafrost intervals have been well studied, but the processes at its base and the impacts of the underlying geology ... -
Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway
(Peer reviewed; Journal article, 2023)The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway. Jostedalsbreen and its meltwater contribute to global sea-level rise and ... -
Plate and stiffener buckling in transversely loaded steel panels
(Journal article, 2023)Stiffened plates may be loaded by axial forces in two directions, i.e., along and transverse to the stiffeners, by in-plane shear force, and by out-of-plane loads as from traffic or water pressure. Special care must be ... -
Antarctic Bedmap data: Findable, Accessible, Interoperable, and Reusable (FAIR) sharing of 60 years of ice bed, surface, and thickness data
(Peer reviewed; Journal article, 2023)One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for predicting future ice loss and the ensuing sea ... -
Multimodal Asynchronous Kalman Filter for monitoring unstable rock slopes
(Peer reviewed; Journal article, 2023)Unstable rock slopes pose a hazard to inhabitants and infrastructure in their vicinity, necessitating advanced monitoring methodologies for timely risk assessment and mitigation. Recent geotechnical monitoring techniques ... -

Seasonal Snowpack Microbial Ecology and Biogeochemistry on a High Arctic Ice Cap Reveals Negligible Autotrophic Activity During Spring and Summer Melt
(Peer reviewed; Journal article, 2023)Snowpack ecosystem studies are primarily derived from research on snow-on-soil ecosystems. Greater research attention needs to be directed to the study of glacial snow covers as most snow cover lies on glaciers and ice ... -
Constraining the tectonic evolution of rifted continental margins by U–Pb calcite dating
(Peer reviewed; Journal article, 2023)We employ U–Pb calcite dating of structurally-controlled fracture fills within crystalline Caledonian basement in western Norway to reveal subtle large-scale tectonic events that affected this rifted continental margin. ... -
Icescape-scale metabolomics reveals cyanobacterial and topographic control of the core metabolism of the cryoconite ecosystem of an Arctic ice cap
(Peer reviewed; Journal article, 2023)Glaciers host ecosystems comprised of biodiverse and active microbiota. Among glacial ecosystems, less is known about the ecology of ice caps since most studies focus on valley glaciers or ice sheet margins. Previously we ... -
Effects of glacier retreat upon glacier-groundwater coupling and biogeochemistry in Central Svalbard
(Peer reviewed; Journal article, 2023)The hydrology and biogeochemistry of perennial groundwater springs emerging in the forefields of retreating Svalbard glaciers are considered through a single-site, multi-year study at Foxfonna, and a multi-site spatial ... -
Use climatic space-for-time substitutions with care: Not only climate, but also local environment affect performance of the key forest species bilberry along elevation gradient
(Peer reviewed; Journal article, 2023)An urgent aim of ecology is to understand how key species relate to climatic and environmental variation, to better predict their prospects under future climate change. The abundant dwarf shrub bilberry (Vaccinium myrtillus ... -
Hydrogen og samspillet mellom teknologi, organisasjon, og diskurs
(Bachelor thesis, 2023)Verden står ovenfor en akselererende klima- og naturkrise, hvor mulighetsvinduet for å forhindre katastrofale konsekvenser er i ferd med å lukke seg. Norge forpliktet seg juridisk til Parisavtalen, og har følgelig mål om ... -
Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen, western Norway
(Peer reviewed; Journal article, 2023)The Jostedalsbreen is the largest ice cap in Norway and mainland Europe. Rapid retreat of many of its outlet glaciers since the 2000s has led to the formation of several glacial lakes. Processes causing the formation and ...
