Trends and internal variability in Brazilian hydropower catchments
(Master thesis, 2023-06-01)Hydropower is a major energy source in Brazil, and long-term hydropower production planning is crucial both for maintaining energy and water security in the country. The amount of water that is available to electricity ... -
Predicting next day’s production in run-of-river hydropower plants using machine learning
(Master thesis, 2023-06-01)This master thesis focuses on time series forecasting using machine learning to predict hourly production in run-of-river hydropower plants. As electrical energy cannot be easily stored, it must be produced and consumed ... -
A Comparative Analysis of Ground Source and Air Source Heat Pumps for Heating of an Office Building in Bergen
(Master thesis, 2023-06-01) -
Experimental Investigation of Silicon Dust Explosions in Pipes
(Master thesis, 2023-06-01)This thesis presents an experimental study of silicon dust explosions in different pipe configurations. The experimental configuration involved a 32-litre explosion vessel connected to pipes of different dimensions, ... -
An Optimization Model for Short-Term Routing and Scheduling of Offshore Wind Maintenance
(Master thesis, 2023-06-01)Maintenance costs constitute a significant portion of the total costs for offshore wind investments. Consequently, a substantial amount of research aims to mitigate these costs. Studies targeting short-term decision-making ... -
The Effects of Diabatic Heating on the Paradigmatic LC1 and LC2 Baroclinic Lifecycles
(Master thesis, 2023-06-01)Extratropical cyclones play a crucial role in determining mid-latitude weather, where the atmosphere is on average inducive to baroclinic instability. Literature has identified two lifecycle behaviors, one that is predominantly ... -
Dealing with uncertainty in ecosystem models along three axes; resolution, forcing and projections
(Doctoral thesis, 2023-05-24)With the imminent threat of climate change, there is an urgent need to understand how warmer temperatures will affect marine ecosystems. Models provide the best tools to study the future, but although great efforts have ... -
Marine Plastic Drift from the Mekong River to Southeast Asia
(Journal article; Peer reviewed, 2023-04-26)Southeast Asia is the world’s most polluted area in terms of marine plastics. The Mekong River is one of the largest rivers in the area, and ranked as somewhere between the 8th- and 11th-biggest contributor to plastics in ... -
A status assessment of selected data synthesis products for ocean biogeochemistry
(Journal article; Peer reviewed, 2023-04-26)Ocean data synthesis products for specific biogeochemical essential ocean variables have the potential to facilitate today’s biogeochemical ocean data usage and comply with the Findable Accessible Interoperable and Reusable ... -
Current shear and turbulence during a near-inertial wave
(Journal article; Peer reviewed, 2023-04-11)Surface currents and turbulent mixing were observed during a near-inertial wave (NIW) using an accousting doppler current profiler (ADCP) and satellite-tracked drifters. Drifter trajectories sampled at three depth levels ... -
Design of Grid-Tied Converter Using AFE
(Master thesis, 2023-03-18)The predicted increase in electricity demand from electrification of the transportation sector has led to research of bidirectional \gls{EV} chargers becoming an ever more popular research topic. With bidirectional chargers, ... -
Leveraging Soil Moisture Assimilation in Permafrost Affected Regions
(Journal article; Peer reviewed, 2023-03-10)The transfer of water and energy fluxes between the ground and the atmosphere is influenced by soil moisture (SM), which is an important factor in land surface dynamics. Accurate representation of SM over permafrost-affected ... -
Factors influencing interannual variability of Belg rain in Ethiopia
(Master thesis, 2023-03-01) -
Development of advanced tools in computational nonlinear aeroelasticity
(Master thesis, 2023-01-04)In this work, the development of a two dimensional computational model for predicting the aeroelastic response is presented. In the aeroelastic model presented here, the aeroedynamic and the structural models are considered ... -
Southern Ocean Control of 2°C Global Warming in Climate Models
(Journal article; Peer reviewed, 2023)Global warming will soon reach the Paris Agreement targets of 1.5°C/2°C temperature increase above pre-industrial levels. Under a business-as-usual scenario, the time to reach these targets varies widely among climate ... -
Rapid sea ice changes in the future Barents Sea
(Journal article; Peer reviewed, 2023)Observed and future winter Arctic sea ice loss is strongest in the Barents Sea. However, the anthropogenic signal of the sea ice decline is superimposed by pronounced internal variability that represents a large source of ... -
Coupled atmosphere–ocean observations of a cold-air outbreak and its impact on the Iceland Sea
(Journal article; Peer reviewed, 2023)Marine cold-air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for the majority of wintertime oceanic heat loss from the subpolar seas of the North Atlantic. However, the impact ... -
Early detection of anthropogenic climate change signals in the ocean interior
(Journal article; Peer reviewed, 2023)Robust detection of anthropogenic climate change is crucial to: (i) improve our understanding of Earth system responses to external forcing, (ii) reduce uncertainty in future climate projections, and (iii) develop efficient ... -
Reconciling conflicting evidence for the cause of the observed early 21st century Eurasian cooling
(Journal article; Peer reviewed, 2023)It is now well established that the Arctic is warming at a faster rate than the global average. This warming, which has been accompanied by a dramatic decline in sea ice, has been linked to cooling over the Eurasian ...
