An Assessment of CO2 Storage and Sea-Air Fluxes for the Atlantic Ocean and Mediterranean Sea Between 1985 and 2018
(Journal article; Peer reviewed, 2024)As part of the second phase of the Regional Carbon Cycle Assessment and Processes project (RECCAP2), we present an assessment of the carbon cycle of the Atlantic Ocean, including the Mediterranean Sea, between 1985 and ... -
In the Wake of Deeper Convection: Nonsteady State Anthropogenic Carbon in the Greenland Sea
(Journal article; Peer reviewed, 2024)We evaluate changes in dissolved inorganic carbon (DIC) in the Greenland Sea between 2002 and 2016, a period characterized by increasing convection depths. We find a mid-depth maximum in anthropogenic carbon (Cant) ... -
Simulated Abrupt Shifts in Aerobic Habitats of Marine Species in the Past, Present, and Future
(Journal article; Peer reviewed, 2024)The physiological tolerances of marine species toward ambient temperature and oxygen can jointly be evaluated in a single metric: the metabolic index. Changes therein characterize a changing aerobic habitat tailored to ... -
The Troll Observing Network (TONe): plugging observation holes in Dronning Maud Land, Antarctica
(Journal article; Peer reviewed, 2024)Understanding how Antarctica is changing and how these changes influence the rest of the Earth is fundamental to the future robustness of human society. Strengthening our understanding of these changes and their implications ... -
Observed Seasonal Evolution of the Antarctic Slope Current System off the Coast of Dronning Maud Land, East Antarctica
(Journal article; Peer reviewed, 2024)The access of heat to the Antarctic ice shelf cavities is regulated by the Antarctic Slope Front, separating relatively warm offshore water masses from cold water masses on the continental slope and inside the cavity. ... -
Implementation of a Simple Actuator Disk for Large-Eddy Simulation in the Weather Research and Forecasting Model (WRF-SADLES v1.2) for wind turbine wake simulation
(Journal article; Peer reviewed, 2024)In this study, we present the development of a Simple Actuator Disk model for Large-Eddy Simulation (SADLES), implemented within the Weather Research and Forecasting (WRF) model, which is widely used in atmospheric research. ... -
An experimental study of foams stabilized by anionic and non-ionic surfactants for geological carbon storage in saline aquifers.
(Master thesis, 2024-06-17)CCS (Carbon Capture and Storage) is regarded as an important contributor in mitigating CO2 emissions and combating climate change. With increased focus on CCS as an option to reduce CO2 emissions, new CCS projects include ... -
Investigating voltage ripple effects in PEM electrolysis: test protocol development and experimental characterisation
(Master thesis, 2024-08-01)PEM water electrolysis is a key technology for producing high-purity hydrogen with a compact design. However, the widespread adoption of PEM electrolysers faces challenges such as the high cost associated with the power ... -
More Frequent Abrupt Marine Environmental Changes Expected
(Journal article; Peer reviewed, 2024)We quantify an elevated occurrence of abrupt changes in ocean environmental conditions under human-induced climate forcing using Earth system model output through a novel analysis method that compares the temporal evolution ... -
A Matheuristic Algorithm for an Offshore Multi-period Location Routing Problem
(Master thesis, 2024-06-28)With the recent increase in energy production generated by offshore wind farms, regular maintenance is important for wind farm owners to ensure that they remain operational. Currently, maintenance tasks are performed by ... -
Bifurcation Points for Tropical Cyclone Genesis and Intensification in Sheared and Dry Environments
(Journal article; Peer reviewed, 2023)The combination of moderate vertical wind shear (VWS) and dry environments can produce the most uncertain scenarios for tropical cyclone (TC) genesis and intensification. We investigated the sources of increased uncertainty ... -
Hyperheuristic Frameworks for Combinatorial Optimization Problems using Deep Reinforcement Learning
(Master thesis, 2024-06-17)Many metaheuristic frameworks exist for solving different combinatorial optimization problems. Despite formulating general strategies that can be applied to many problems, they often rely on problem-specific implementation. ... -
Rogue waves: Results of the ExWaMar project
(Journal article; Peer reviewed, 2024)Rogue waves, also known as freak waves, have received much attention in the scientific community as well as in media and the marine industry in the past two decades. Forecasts of extreme weather events have always been ... -
Projecting Spring Consecutive Rainfall Events in the Three Gorges Reservoir based on Treble-Nested dynamical downscaling
(Journal article; Peer reviewed, 2024)Spring consecutive rainfall events (CREs) are key triggers of geological hazards in the Three Gorges Reservoir area (TGR), China. However, previous projections of CREs based on the direct outputs of global climate models ... -

Modeling and stability analysis of a sliding bead from a problem-based learning perspective
(Journal article; Peer reviewed, 2023)In this work, we adopt a problem-based learning approach to develop an integrative bachelor project that relies on competences acquired from basic courses in mathematics, mechanics and computation. In this sense, the ... -
Characterizing Atlantic interhemispheric teleconnection established by South American monsoon in austral summer
(Journal article; Peer reviewed, 2023)This study aims to characterize the interhemispheric teleconnection pattern, which is established by the South America (SA) summer monsoon over the Atlantic Ocean during January and February, and referred it as the Atlantic ... -
Evaluation of sea surface roughness parameterization in meso-to-micro scale simulation of the offshore wind field
(Journal article; Peer reviewed, 2023)Accurate parameterization of the wind-induced effects on the Marine Atmospheric Boundary Layer (MABL) is of fundamental importance for many applications including weather forecasting and offshore wind energy. Roughness ... -
Long-time principal geodesic analysis in director-based dynamics of hybrid mechanical systems
(Journal article; Peer reviewed, 2023)In this article, we investigate an extended version of principal geodesic analysis for the unit sphere S2 and the special orthogonal group SO(3). In contrast to prior work, we address the construction of long-time smooth ... -
