Linking scales of sea ice surface topography: evaluation of ICESat-2 measurements with coincident helicopter laser scanning during MOSAiC
(Peer reviewed; Journal article, 2023)Information about sea ice surface topography and related deformation is crucial for studies of sea ice mass balance, sea ice modeling, and ship navigation through the ice pack. The Ice, Cloud, and land Elevation Satellite-2 ... -
Using Mask R-CNN for Underwater Fish Instance Segmentation as Novel Objects: A Proof of Concept
(Journal article; Peer reviewed, 2023)Instance Segmentation in general deals with detecting, segmenting and classifying individual instances of objects in an image. Underwater instance segmentation methods often involve aquatic animals like fish as the things ... -
Environmental risk assessment of an underwater acoustic mobile network
(Lecture, 2022)Underwater vehicles make inspections and surveillance safer and with a lower carbon footprint than ship-based operations. However, to effectively operate them, they need robust positioning and communication systems. One ... -
Sea surface height anomaly and geostrophic current velocity from altimetry measurements over the Arctic Ocean (2011–2020)
(Peer reviewed; Journal article, 2023)Satellite altimetry missions flying over the ice-covered Arctic Ocean have opened the possibility of further understanding changes in the ocean beneath the sea ice. This requires complex processing of satellite signals ... -
Microbial hydrogen consumption leads to a significant pH increase under high-saline-conditions: implications for hydrogen storage in salt caverns
(Peer reviewed; Journal article, 2023)Salt caverns have been successfully used for natural gas storage globally since the 1940s and are now under consideration for hydrogen (H2) storage, which is needed in large quantities to decarbonize the economy to finally ... -
The evolution of the Fram Strait sea ice volume export decomposed by age: estimating with parameter-optimized sea ice-ocean model outputs
(Peer reviewed; Journal article, 2023)Sea ice export through the Fram Strait is crucial in the dynamic evolution of Arctic sea ice and can further modulate Arctic sea ice mass balance as well as the ocean thermohaline circulation. In this study, based on outputs ... -
HYDROGEN POWERED VESSELS AT SEA:FUEL CELL & BATTERY UPSCALING
(Chapter, 2022)There is today a strong effort in developing fuel cell / battery systems for ship propulsion to achieve zero-emission maritime transport, in accordance with UN sustainability goals and the Fit For 55 plan to achieve the ... -
Promoting exercise training and physical activity in daily life: a feasibility study of a virtual group intervention for behaviour change in COPD
(Peer reviewed; Journal article, 2018)Background Physical inactivity is associated with poor health outcomes in chronic obstructive pulmonary disease (COPD). It is therefore crucial for patients to have a physically active lifestyle. The aims of this feasibility ... -
Deep learning for graphs
(Chapter, 2018)Deep learning for graphs encompasses all those neural models endowed with multiple layers of computation operating on data represented as graphs. The most common building blocks of these models are graph encoding layers, ... -
Treatment fidelity in a pragmatic clinical trial of music therapy for premature infants and their parents: the LongSTEP study
(Peer reviewed; Journal article, 2023)Background Treatment fidelity (TF) refers to methodological strategies used to monitor and enhance the reliability and validity of interventions. We evaluated TF in a pragmatic RCT of music therapy (MT) for premature ... -
Automatic Measurement of the Dependence on Pressure and Temperature of the Mass Density of Drilling Fluids
(Peer reviewed; Journal article, 2022)Drilling fluids are subject to substantial variations in pressure and temperature while they are circulated in a well. These changes are so great that the mass density of the drilling fluid varies significantly during ... -
The Extended Timing Annotation Dataset for Sentinel-1-Product Description and First Evaluation Results
