The light in the dark: In-situ biorefinement of crude oil to hydrogen using typical oil reservoir Thermotoga strains
(Peer reviewed; Journal article, 2021)H2 is a CO2 free energy carrier that can be produced biologically through dark fermentation using specific bacteria. In general, biological production of H2 needs a carbon source and is more efficient at higher temperatures. ... -
LIME: Software for 3-D visualization, interpretation, and communication of virtual geoscience models
(Peer reviewed; Journal article, 2019)The use of three-dimensional (3-D), photo-textured representations of topography from laser scanning and photogrammetry is becoming increasingly common across the geosciences. This rapid adoption is driven by recent ... -
Limits of 3D target detectability of logging while drilling deep-sensing electromagnetic measurements from numerical modeling
(Peer reviewed; Journal article, 2023)Subsurface energy resources are often found in three-dimensional and non-spatially continuous rock formations that exhibit electrical anisotropy. Deep-sensing tri-axial borehole electromagnetic measurements are currently ... -
Linking scales of sea ice surface topography: evaluation of ICESat-2 measurements with coincident helicopter laser scanning during MOSAiC
(Peer reviewed; Journal article, 2023)Information about sea ice surface topography and related deformation is crucial for studies of sea ice mass balance, sea ice modeling, and ship navigation through the ice pack. The Ice, Cloud, and land Elevation Satellite-2 ... -
A locally conservative multiphase level set method for capillary-controlled displacements in porous media
(Peer reviewed; Journal article, 2021)We present a multiphase level set method with local volume conservation for capillary-controlled displacement in porous structures. Standard numerical formulations of the level set method for capillary-controlled (or, ... -
Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation
(Peer reviewed; Journal article, 2020)Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ... -
Long-Term Water Surface Area Monitoring and Derived Water Level Using Synthetic Aperture Radar (SAR) at Altevatn, a Medium-Sized Arctic Lake
(Peer reviewed; Journal article, 2019)Monitoring water storage in lakes and reservoirs is critical to water resource management, especially in a changing climate. Satellite microwave remote sensing offers a weather and light-independent solution for mapping ... -
Lumikot: Fast auroral transients during the growth phase of substorms
(Peer reviewed; Journal article, 2019)The development of a magnetospheric substorm may be classified into three phases: growth, expansion, and recovery. The growth phase is important as it includes processes that lead to the expansion. In a recent growth-phase ... -
Machine learning reveals regime shifts in future ocean carbon dioxide fluxes inter-annual variability
(Peer reviewed; Journal article, 2024)The inter-annual variability of global ocean air-sea CO2 fluxes are non-negligible, modulates the global warming signal, and yet it is poorly represented in Earth System Models (ESMs). ESMs are highly sophisticated and ... -
Manx Arrays: Perfect Non-Redundant Interferometric Geometries
(Peer reviewed; Journal article, 2022)Interferometry applications (e.g., radio astronomy) often wish to optimize the placement of the interferometric elements. One such optimal criterion is a uniform distribution of non-redundant element spacings (in both ... -
Mapping and characterization of unstable slopes with Sentinel-1 multi-geometry InSAR (activity line 2: public sector applications)
(Research report, 2020)This is a high-level report that summarizes the main achievements and results of the research and development conducted in the project “Mapping and Characterization of unstable slopes with Sentinel-1 multi-geometry InSAR ... -
Marginalized iterative ensemble smoothers for data assimilation
(Journal article; Peer reviewed, 2023)Data assimilation is an important tool in many geophysical applications. One of many key elements of data assimilation algorithms is the measurement error that determines the weighting of the data in the cost function to ... -

Mathematics and Medicine: How mathematics, modelling and simulations can lead to better diagnosis and treatments
(Peer reviewed; Journal article, 2019)Starting with the discovery of X-rays by Röntgen in 1895, the progress in medical imaging has been extraordinary and immensely beneficial to diagnosis and therapy. Parallel to the increase of imaging accuracy, there is the ... -
Measurement of snow water equivalent using drone-mounted ultra-wide-band radar
(Peer reviewed; Journal article, 2021)The use of unmanned aerial vehicle (UAV)-mounted radar for obtaining snowpack parameters has seen considerable advances over recent years. However, a robust method of snow density estimation still needs further development. ... -
The Melanocortin System in Atlantic Salmon (Salmo salar L.) and Its Role in Appetite Control
(Peer reviewed; Journal article, 2020)The melanocortin system is a key neuroendocrine network involved in the control of food intake and energy homeostasis in vertebrates. Within the hypothalamus, the system comprises two main distinct neuronal cell populations ... -
Memento: Localized time‐warping for spatio‐temporal selection
(Peer reviewed; Journal article, 2019)Interaction techniques for temporal data are often focused on affecting the spatial aspects of the data, for instance through the use of transfer functions, camera navigation or clipping planes. However, the temporal aspect ... -
Metamodeling of the Electrical Conditions in Submerged Arc Furnaces
(Peer reviewed; Journal article, 2021)Physics-based Finite Element Methods models can be used to investigate the electrical conditions in submerged arc furnaces (SAFs). However, their explicit solution may be very demanding in terms of time and computational ... -
Metanfangst fra melke- og kjøttproduksjon i driftsbygninger
