Targeted risk assessment of mercury exposure of recreational fishers: Are nephrops fishers in Norway at risk?
(Journal article; Peer reviewed, 2021)Recreational fishers often consume their catch, which may expose them to environmental contaminants. However, targeted risk assessment for exceeding the tolerable weekly intake (TWI) of a specific contaminant is often ... -
Trophic structure of mesopelagic species in the Northeast Atlantic Ocean based on stable isotopes of carbon and nitrogen
(Master thesis, 2021-09-03)The mesopelagic zone is one of the largest, yet among the least explored habitats of the planet. Possible estimates of fish living in this zone range from around 1 to 15 billon tones of biomass which is 10 to 15 times that ... -
Calibration of oxygen 1s ionization energies. Accurate energies for CO2, H2O, CO, and O2
(Journal article; Peer reviewed, 2021)Access to accurate reference data is a prerequisite in order to translate chemical shifts to an absolute scale for inner-shell ionization energies. Calibration standards for oxygen 1s (O 1s) ionization energies are less ... -
Coastal submesoscale processes and their effect on phytoplankton distribution in the southeastern Bay of Biscay
(Journal article; Peer reviewed, 2021)Submesoscale processes have a determinant role in the dynamics of oceans by transporting momentum, heat, mass, and particles. Furthermore, they can define niches where different phytoplankton species flourish and accumulate ... -
Polar lows – moist-baroclinic cyclones developing in four different vertical wind shear environments
(Journal article; Peer reviewed, 2021)Polar lows are intense mesoscale cyclones that develop in polar marine air masses. Motivated by the large variety of their proposed intensification mechanisms, cloud structure, and ambient sub-synoptic environment, we use ... -
The Covid-19 shutdown: when studying turns digital, students want more structure
(Journal article; Peer reviewed, 2021)In March 2020, universities in Norway and many other countries shut down due to the Covid-19 pandemic. The students lost access to classrooms, libraries, study halls, and laboratories. Studying turned digital. Because it ... -
Probabilistic Tsunami Hazard and Risk Analysis: A Review of Research Gaps
(Journal article; Peer reviewed, 2021)Tsunamis are unpredictable and infrequent but potentially large impact natural disasters. To prepare, mitigate and prevent losses from tsunamis, probabilistic hazard and risk analysis methods have been developed and have ... -
Improved seismic monitoring with OBS deployment in the Arctic: A pilot study from offshore western Svalbard
(Journal article; Peer reviewed, 2021)The mid‐ocean ridge system is the main source of earthquakes within the Arctic region. The earthquakes are recorded on the permanent land‐based stations in the region, although, smaller earthquakes remain undetected. In ... -
Integrating Cognitive Learning Strategies into Physics Instruction : Developing students’ approaches to physics and learning
(Doctoral thesis, 2021-03-24)Introductory physics courses are obligatory for many disciplines outside of physics. As experienced by many students, they are notoriously difficult, often with high failure rates. Many students, whether they passed or ... -
Mostar index and edge Mostar index of polymers
(Journal article; Peer reviewed, 2021)Let G=(V,E) be a graph and e=uv∈E. Define nu(e,G) be the number of vertices of G closer to u than to v. The number nv(e,G) can be defined in an analogous way. The Mostar index of G is a new graph invariant defined as ... -
Effect of different arachidonic acid levels in broodstock diet on egg quality of ballan wrasse (Labrus bergylta)
(Master thesis, 2021-07-31)The production of ballan wrasse (Labrus bergylta) is growing and is becoming a focus area for the aquaculture industry. As a result of rising louse numbers and problems with resistance, biological methods such as cleaner ... -
Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
(Journal article; Peer reviewed, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
Teaching with digital geology in the high Arctic: opportunities and challenges
(Journal article; Peer reviewed, 2021)The Covid-19 pandemic occurred at a time of major revolution in the geosciences – the era of digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric ... -
Semantics of multiway dataflow constraint systems
(Journal article; Peer reviewed, 2021)Multiway dataflow constraint systems (MDCS) is a programming model where statements are not executed in a predetermined order. Rather, individual methods are selected from specific method sets and then executed to achieve ... -
Specifying with syntactic theory functors
(Journal article; Peer reviewed, 2020)We propose a framework, syntactic theory functors (STFs), for creating syntactic structuring mechanisms for specification languages. Good support for common reuse patterns is important for systematically developing ... -

Typical Sequences Revisited - Computing Width Parameters of Graphs
(Journal article; Peer reviewed, 2021)In this work, we give a structural lemma on merges of typical sequences, a notion that was introduced in 1991 [Lagergren and Arnborg, Bodlaender and Kloks, both ICALP 1991] to obtain constructive linear time parameterized ... -
Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning?
(Journal article; Peer reviewed, 2021)Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ... -
Pre-catch and discard mortality in Northeast Atlantic herring and mackerel fisheries: consequences for stock estimates and advice
(Journal article; Peer reviewed, 2021)Unaccounted mortality caused by discarding or pre-catch losses is a major challenge for fisheries management. In pelagic fisheries, a considerable proportion of catches may be lost due to intentional release of unwanted ... -
Lower-thermosphere–ionosphere (LTI) quantities: current status of measuring techniques and models
(Journal article; Peer reviewed, 2021)The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the lower part of the ionosphere and as such comprises a complex system coupled to both the atmosphere below and space above. The atmospheric ...
