Calibration of the ALICE Photon Spectromter (PHOS) using the neutral pion to gamma gamma decay
(Master thesis, 2009-09-01)The Large Hadron Collider (LHC) is under construction beneath the border between Switzerland and France. If it is successful, it will accelerate and collide protons at 7 T eV per proton in center of mass. Furthermore, it ... -
Calibration of the photon spectrometer PHOS of the ALICE experiment
(Peer reviewed; Journal article, 2019)The procedure for the energy calibration of the high granularity electromagnetic calorimeter PHOS of the ALICE experiment is presented. The methods used to perform the relative gain calibration, to evaluate the geometrical ... -
Calibration, validation and application of the foraminiferal Mg/Ca. Reconstructing the intermediate water masses structure and origin in the Western Tropical Atlantic
(Doctoral thesis, 2015-05-22)The Atlantic Meridional Overturning Circulation (AMOC) plays a central role in the northward distribution of heat. It is a key mechanism in the climatic system that needs to be further understood. Most studies focused on ... -
Caligus elongatus and Lepeophtheirus salmonis infestation on farmed and wild fish.
(Master thesis, 2022-02-07) -
Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
(Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
Caligus rogercresseyi acetylcholinesterase types and variants: a potential marker for organophosphate resistance
(Peer reviewed; Journal article, 2018-10-30)Background Control of the sea louse Caligus rogercresseyi in the Chilean salmonid industry is reliant on chemical treatments. Azamethiphos was introduced in 2013, although other organophosphates were previously used. In ... -
CALOTRITON: a convective boundary layer height estimation algorithm from ultra-high-frequency (UHF) wind profiler data
(Journal article; Peer reviewed, 2024)Long time series of observations of atmospheric dynamics and composition are collected at the French Pyrenean Platform for Observation of the Atmosphere (P2OA). Planetary boundary layer depth is a key variable of the climate ... -
Calving rates at tidewater glaciers vary strongly with ocean temperature
(Peer reviewed; Journal article, 2015-10-09)Rates of ice mass loss at the calving margins of tidewater glaciers (frontal ablation rates) are a key uncertainty in sea level rise projections. Measurements are difficult because mass lost is replaced by ice flow at ... -
Cambrian (Series 3 - furongian) conodonts from the alum shale formation at Slemmestad, Oslo region, Norway
(Peer reviewed; Journal article, 2018-05-09)Nine samples from the Alum Shale of Slemmestad, Oslo Region, were processed for conodonts. The limestone-rich interval extending from the mid Cambrian Paradoxides paradoxissimus trilobite Zone to the Lower Ordovician ... -
Can a dual pulsed lidar system measure the lateral coherence of turbulence?
(Master thesis, 2023-08-10)Characterizing the coherence of turbulence in the marine boundary layer faces a significant challenge due to the limited availability of offshore measurements within the relevant altitude ranges, particularly up to 250 m. ... -
Can an old alien benefit from rising ocean temperatures? An experimental and field study on the growth and local distribution of Codium fragile subsp. fragile (Chlorophyta)
(Peer reviewed; Journal article, 2017-06)Codium fragile subsp. fragile (hereafter C. fragile) is a widespread non-native chlorophyte. Experimental and observational approaches were used to examine the influence of temperature on its growth and local distribution ... -
Can Areawide Building Retrofitting Affect the Urban Microclimate? An LES Study for Berlin, Germany
(Journal article; Peer reviewed, 2022)In this work, we investigate the effect of areawide building retrofitting on summertime, street-level outdoor temperatures in an urban district in Berlin, Germany. We perform two building-resolving, weeklong large-eddy ... -
Can bryophyte groups increase functional resolution in tundra ecosystems?
(Journal article; Peer reviewed, 2021)The relative contribution of bryophytes to plant diversity, primary productivity, and ecosystem functioning increases towards colder climates. Bryophytes respond to environmental changes at the species level, but because ... -
Can catch data from small meshed gears in shallow waters be used to estimate recruitment indices of Norwegian coastal cod, Northeast Arctic saithe and pollack along the Norwegian coast?
(Master thesis, 2019-06-21)Shallow waters (<30 meters) are important nursery areas for coastal cod, saithe and pollack, before they recruit to their respective fisheries at an age around 3 years old. Still, no study provides information on fish ... -
Can enrichment improve the post-release survival of hatchery-reared Atlantic salmon fry (Salmo salar)? – A field experiment
(Master thesis, 2018-06-26)Release of captive-reared fish to supplement reduced, wild populations has become a common tool for conservation and management. Such attempted population enhancements have, however, had limited success, and several previous ... -
Can environmental toxins increase parasite fitness? Ecotoxicological studies on the effects of microcystin on the host-parasite dynamics of Schistocephalus solidus
(Master thesis, 2020-08-21)Background: Eutrophication of aquatic biomes and exacerbated climate change effects are expected to result in a global increase in harmful cyanobacterial blooms. Cyanotoxins are detrimental to animal health, but how they ... -
