Changes in water temperature and oxygen: the effect of triploidy on performance and metabolism in large farmed Atlantic salmon
(Peer reviewed; Journal article, 2018)In salmon farming, the use of sterile triploids (3N) can mitigate the problem of escapees interbreeding with wild salmon. However, triploid salmon appear less tolerant to high water temperatures and low oxygen levels ... -
Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient
(Peer reviewed; Journal article, 2017)Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ... -
Changing provenance and stratigraphic signatures across the Triassic–Jurassic boundary in eastern Spitsbergen and the subsurface Barents Sea
(Journal article; Peer reviewed, 2022)A change to more sandstone dominated deposits and increasing condensation across the Triassic–Jurassic boundary is generally associated with improved reservoir quality in the Barents Sea. However, spatial and temporal ... -
Characteriazation of immunogenic surface proteins of Pasteurella altantica genomvar salmonicida
(Master thesis, 2024-06-03)Pasteurellosis caused by Pasteurella atlantica genomvar salmonicida has been an emerging disease in Norway since 2018, causing poor fish welfare and mortalities in the fish farming industry. The development of a commercial ... -
Characterisation of a Digital Sampling Calorimeter Prototype for Proton Computed Tomography With Electron Beams
(Master thesis, 2020-12-19)Proton CT is a novel imaging modality designed to improve dose planning and treatment monitoring in proton therapy. The precision of the beam of charged particles, like protons, requires accurate diagnostics, to avoid ... -
Characterisation of extensional faults in carbonate rocks (Suez Rift, Egypt); with particular focus on the role of shale smear
(Master thesis, 2012-04-27)The distribution, composition and flow-properties of fault core and shale smear along faults in carbonate reservoirs is less well understood compared to faults in siliciclastic rocks. This study uses field data to characterize ... -
Characterisation of Single Wind Turbine Wakes with Static and Scanning WINTWEX-W LiDAR Data
(Peer reviewed; Journal article, 2015)With further development of LiDAR technology wake measurements by use of LiDAR became of common interest in the wind energy community. To study new measurement strategies of scanning and nacelle LiDARs, in combination with ... -
Characterisation of the paralytic shellfish toxin biosynthesis gene clusters in Anabaena circinalis AWQC131C and Aphanizomenon sp. NH-5
(Peer reviewed; Journal article, 2009-03-30)Background: Saxitoxin and its analogues collectively known as the paralytic shellfish toxins (PSTs) are neurotoxic alkaloids and are the cause of the syndrome named paralytic shellfish poisoning. PSTs are produced by a ... -
Characterising Mesoscale Fast Flow Channels in the Polar Cap Ionosphere
(Doctoral thesis, 2021-01-22)The large-scale ionospheric convection that circulates in the high-latitude polar caps was initially assumed to be a smooth, laminar flow. However, it has now come to light that this is an oversimplified understanding of ... -
Characterising the local and intense water cycle during a cold air outbreak in the Nordic Seas
(Journal article; Peer reviewed, 2018)Air masses in marine cold air outbreaks (CAOs) at high latitudes undergo a remarkable diabatic transformation because of the uptake of heat and moisture from the ocean surface, and the formation of precipitation. In this ... -
Characteristics and Meteorological Environment of Terrestrial Gamma-ray Flashes
(Doctoral thesis, 2021-05-28)This thesis investigates the geographic and meteorological conditions in which Terrestrial Gamma-ray Flashes (TGFs) are produced. TGFs are submillisecond bursts of gamma radiation produced inside thunderclouds in association ... -
Characteristics and Transformation of Pacific Winter Water on the Chukchi Sea Shelf in Late Spring
(Peer reviewed; Journal article, 2019)Data from a late spring survey of the northeast Chukchi Sea are used to investigate various aspects of newly ventilated winter water (NVWW). More than 96% of the water sampled on the shelf was NVWW, the saltiest (densest) ... -
Characteristics of 454 pyrosequencing data—enabling realistic simulation with flowsim
(Peer reviewed; Journal article, 2010)Motivation: The commercial launch of 454 pyrosequencing in 2005was a milestone in genome sequencing in terms of performance and cost. Throughout the three available releases, average read lengths have increased to ∼500 ... -
Characteristics of Cold-Air Outbreak Events and Associated Polar Mesoscale Cyclogenesis over the North Atlantic Region
(Journal article; Peer reviewed, 2021)Equatorward excursions of cold polar air masses into ice-free regions, so-called Cold Air Outbreaks (CAO), are frequently accompanied by the development of severe mesoscale weather features. Focusing on two key regions, ... -
Characteristics of cyclones following different pathways in the Gulf Stream region
(Journal article; Peer reviewed, 2021)The Northwest Atlantic is a region of strong temperature gradients and hence is a favourable location for wintertime cyclone intensification co-located with the storm track. The temperature gradient is associated with both ... -
Characteristics of DNA polymerase I from an extreme thermophile, Thermus scotoductus strain K1
(Journal article; Peer reviewed, 2021)Several native and engineered heat-stable DNA polymerases from a variety of sources are used as powerful tools in different molecular techniques, including polymerase chain reaction, medical diagnostics, DNA sequencing, ... -
Characteristics of fragmented aurora-like emissions (FAEs) observed on Svalbard
(Journal article; Peer reviewed, 2021)This study analyses the observations of a new type of small-scale aurora-like feature, which is further referred to as fragmented aurora-like emission(s) (FAEs). An all-sky camera captured these FAEs on three separate ... -
