Rapid Landscape Changes in Plastic Bays Along the Norwegian Coastline
(Journal article; Peer reviewed, 2021)The Norwegian Coastal Current transports natural debris and plastic waste along the Norwegian coastline. Deposition occurs in so-called wreck-bays and includes floating debris, such as seaweed, driftwood and volcanic pumice, ... -
Structure-Activity-Relationship-Aided Design and Synthesis of xCT Antiporter Inhibitors
(Journal article; Peer reviewed, 2021)The xCT antiporter is a cell membrane protein involved in active counter-transportation of glutamate (outflux) with cystine (influx) over the human cell membrane. This feature makes the xCT antiporter a crucial element of ... -
A deep learning-based method to identify and count pelagic and mesopelagic fishes from trawl camera images
(Journal article; Peer reviewed, 2021)Fish counts and species information can be obtained from images taken within trawls, which enables trawl surveys to operate without extracting fish from their habitat, yields distribution data at fine scale for better ... -
Physical and nutrient stimuli differentially modulate gut motility patterns, gut transit rate, and transcriptome in an agastric fish, the ballan wrasse
(Journal article; Peer reviewed, 2021-02-11)The effects of nutrient and mechanical sensing on gut motility and intestinal metabolism in lower vertebrates remains largely unknown. Here we present the transcriptome response to luminal stimulation by nutrients and an ... -
Diversity, distribution and phylogenetic affinities of deep-sea lithistids (Porifera, Heteroscleromorpha) of the Azores archipelago
(Journal article; Peer reviewed, 2021-05-28)Lithistid sponges are globally distributed in temperate and sub-tropical areas, constituting an important component of deep-sea benthic communities where they form structurally complex and vulnerable marine ecosystems ... -
Automatic interpretation of salmon scales using deep learning
(Journal article; Peer reviewed, 2021)For several fish species, age and other important biological information is manually inferred from visual scrutinization of scales, and reliable automatic methods are not widely available. Here, we apply Convolutional ... -
Ignition of high-pressure hydrogen releases – Experimental study of impinging and non-impinging releases through a fast-acting valve, with and without a burst disc downstream of the valve
(Master thesis, 2021-09-14)A wide consensus of climate research indicates that anthropogenic greenhouse gas emissions affect the climate and causes the global mean temperature to rise compared to preindustrial levels. International treaties such as ... -
Pasteurella atlantica in Norwegian lumpsuckers : Characterisation, pathogenicity, vaccine development and immune responses
(Doctoral thesis, 2021-12-16)Lumpsuckers (Cyclopterus lumpus L.) have gained popularity as a cleaner fish to biologically control salmon lice infestations in farmed Atlantic salmon in Norway. Starting in 2012, most producers in Norway have been raising ... -
Seismic modelling and deconvolution of prestack depth migrated images through ray-based Point-Spread Functions
(Doctoral thesis, 2021-12-15)Seismic modelling involves simulating the propagation of waves through an Earth model to retrieve information about the subsurface. If an a priori Earth model is known, seismic modelling allows geoscientists to assess how ... -
Optimizing storage of fish feed – An experimental study on maximizing the available space at Skretting's storage facility.
(Master thesis, 2021-10-17)In this Master's thesis I develop a mixed integer linear programming (MILP) optimization model. The model is designed to propose storage placements for upcoming production of fish feed. -
Land-use and climate impacts on drought resistance and resilience in coastal heathland ecosystems
(Doctoral thesis, 2021-12-15)Background: Coastal heathlands of north-western Europe are semi-natural landscapes of high conservation value. These are ancient and historically widespread landscapes, but anthropogenic land-use and climate change are now ... -

Water shutoff and conformance improvement: an introduction
(Journal article; Peer reviewed, 2021)This paper provides an introduction to the topic of water shutoff and conformance improvement. After indicating the volumes of water produced during oilfield operations, a strategy is provided for attacking excess water ... -
A Microbial Nitrogen Engine Modulated by Bacteriosyncytia in Hexactinellid Sponges: Ecological Implications for Deep-Sea Communities
(Journal article; Peer reviewed, 2021-03-17)Hexactinellid sponges are common in the deep sea, but their functional integration into those ecosystems remains poorly understood. The phylogenetically related species Schaudinnia rosea and Vazella pourtalesii were herein ... -
Material properties particularly suited to be measured with helium scattering: selected examples from 2D materials, van der Waals heterostructures, glassy materials, catalytic substrates, topological insulators and superconducting radio frequency materials
(Journal article; Peer reviewed, 2021)Helium Atom Scattering (HAS) and Helium Spin-Echo scattering (HeSE), together helium scattering, are well established, but non-commercial surface science techniques. They are characterised by the beam inertness and very ... -
Microbial colonization and community stability in a marine post-smolt RAS inoculated with a commercial starter culture
(Journal article; Peer reviewed, 2021)The performance of a commercial starter culture was investigated in a new marine post-smolt RAS, analyzing the microbial communities of 100 samples collected monthly over a year from biofilter biofilm carriers, tank wall ... -
Signal estimation in on/off measurements including event-by-event variables
(Journal article; Peer reviewed, 2021)Signal estimation in the presence of background noise is a common problem in several scientific disciplines. An “on/off” measurement is performed when the background itself is not known, being estimated from a background ... -
In Vacuo Dispersion-Like Spectral Lags in Gamma-Ray Bursts
(Journal article; Peer reviewed, 2021)Some recent studies exposed preliminary but rather intriguing statistical evidence of in vacuo dispersion-like spectral lags for gamma-ray bursts (GRBs), a linear correlation between time of observation and energy of GRB ... -
Semi‐automatic Ice Rafted Debris quantification with Computed Tomography
(Journal article; Peer reviewed, 2021)Sedimentary ice-rafted debris (IRD) provides critical information about the climate sensitivity and dynamics of ice sheets. In recent decades, high-resolution investigations have revelated ice rafting events in response ... -
Impact of the Agulhas Current on Southern Africa Precipitation: A Modeling Study
(Journal article; Peer reviewed, 2021)The Agulhas Current (AC) creates a sharp temperature gradient with the surrounding ocean, leading to a large turbulent flux of moisture from ocean to atmosphere. We use two simulations of the Weather Research and Forecasting ...
