Five decades of warming: impacts on snow cover in Norway
(Journal article, 2018)Northern latitudes are experiencing faster warming than other regions in the world, which is partly explained by the snow albedo feedback. In Norway, mean temperatures have been increasing since the 1990s, with 2014 being ... -
Flame curtain kilns produce biochar from dry biomass with minimal methane emissions
(Peer reviewed; Journal article, 2023) -
Flow cone – new CPTU add-on module trialled in Halden silt
(Chapter, 2022) -
Fluid flow and pore pressure development throughout the evolution of a trough mouth fan, western Barents Sea
(Peer reviewed; Journal article, 2018)Using a combination of geophysical and geotechnical data from Storfjorden Trough Mouth Fan off southern Svalbard, we investigate the hydrogeology of the continental margin and how this is affected by Quaternary glacial ... -
Fluid‐Rock Interactions in Clay‐Rich Seals: Impact on Transport and Mechanical Properties
(Chapter, 2018)Fluid‐rock interaction in low‐permeable clay‐rich seal units is an important topic for the evaluation of the long‐term seal integrity during geological storage of CO2. In low‐permeable sealing units, the diffusion of CO2 ... -
Fluorinated Precursor Compounds in Sediments as a Source of Perfluorinated Alkyl Acids (PFAA) to Biota
(Peer reviewed; Journal article, 2020)The environmental behavior of perfluorinated alkyl acids (PFAA) and their precursors was investigated in lake Tyrifjorden, downstream a factory producing paper products coated with per- and polyfluorinated alkyl substances ... -
Fonnbu, a new (old) platform for snow and avalanche research.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)One of the first tasks of the newly established avalanche group at the NGI in 1973 was the selection of a suitable location for an avalanche research station. The choice was on Grasdalen, north of the Jotunheimen mountains, ... -
Forcasting snow avalanche days from meteorological data using classification trees; Grasdalen, Western Norway
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)Avalanches pose one of the most serious problems to infrastructure and people in the mountains in Norway. Processes leading to avalanche release are deterministic but the time and place of avalanche release is notoriously ... -
Forecast of avalanche danger for the intracontinental regions of Northeast of Eurasia
(NGI Publication;203, Chapter, 1998)The research area includes the Kolyma riverhead with tributaries. For this territory the extreme continental climate with very frost winters is common. The duration of snow cover is 200-230 days. The domination of low ... -

Forecasting the fatal Longyearbyen avalanche. Possibilities and challenges
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)One of the main questions after the fatal avalanche in Longyearbyen in December 2015, where two persons perished and eleven houses were destroyed, was whether an active avalanche warning system would have identified the ... -
Formation and availability of methylmercury in mercury-contaminated sediment: effects of activated carbon and biochar amendments
(Peer reviewed; Journal article, 2022)Purpose As the formation of toxic and bioaccumulative methylmercury (MeHg) in Hg-contaminated sediments is of great concern worldwide, suitable remediation options are needed. Activated carbon (AC) amendment is a contested ... -
Formulation of non-coaxial plastic dissipation and stress–dilatancy relations for geomaterials
(Peer reviewed; Journal article, 2020)Stress–dilatancy theories play a central role in the modeling of the plastic dissipation of geomaterials. There exist several mathematical frameworks for describing the stress–dilatancy behavior of soils. One of the limiting ... -
Fourfold Increase in Pumpkin Yield in Response to Low-Dosage Root Zone Application of Urine-Enhanced Biochar to a Fertile Tropical Soil
(Journal article, 2015)A widely abundant and invasive forest shrub, Eupatorium adenophorum, was pyrolyzed in a cost-efficient flame curtain kiln to produce biochar. The resulting biochar fulfilled all the requirements for premium quality, according ... -
Fracture attribute scaling and connectivity in the Devonian Orcadian Basin with implications for geologically equivalent sub-surface fractured reservoirs
(Peer reviewed; Journal article, 2020)Fracture attribute scaling and connectivity datasets from analogue systems are widely used to inform sub-surface fractured reservoir models in a range of geological settings. However, significant uncertainties are associated ... -
Fragility Assessment of Transportation Infrastructure Systems Subjected to Earthquakes
(Chapter, 2018)This paper provides a review of the different methodologies for the fragility assessment of critical transportation infrastructure subjected to earthquake excitations with emphasis placed on geotechnical effects. Available ... -
Fragility of transport assets exposed to multiple hazards: State-of-the-art review toward infrastructural resilience
(Journal article; Peer reviewed, 2019)Vulnerability is a fundamental component of risk and its understanding is important for characterising the reliability of infrastructure assets and systems and for mitigating risks. The vulnerability analysis of infrastructure ... -
Framework for Planning and Evaluation of Nature-Based Solutions for Water in Peri-Urban Areas

Frictional Properties and Seismogenic Potential of Caprock Shales
(Peer reviewed; Journal article, 2020)Fractures and faults are critical elements affecting the geomechanical integrity of CO2 storage sites. In particular, the slip of fractures and faults may affect reservoir integrity and increase potential for breach, may ...
