Expanding the scientific basis for how the world can monitor and manage natural resources.
(University of Copenhagen, and NORDECO (Nordic Foundation for Development and Ecology), Copenhagen, Denmark, 2016)
This D.Sc. thesis presents research into the theory, practice, application and results of ‘citizen science’ as applied in the developing world (Africa, South East Asia, Latin America) and in the Arctic (Greenland). It ...
Learning Polar Encodings for Arbitrary-Oriented Ship Detection in SAR Images.
(2021)
Common horizontal bounding box-based methods are not capable of accurately locating slender ship targets with arbitrary orientations in synthetic aperture radar (SAR) images. Therefore, in recent years, methods based on ...
Prediction of Dominant Ocean Parameters for Sustainable Marine Environment.
(2021)
Prediction of ocean parameters is the rising interest in ocean-related fields to perceive variations in climatic conditions. Most of the existing methods reveal that predictions involve a single parameter, namely Sea Surface ...
Pollution in the Arctic Ocean: An overview of multiple pressures and implications for ecosystem services.
(2022)
The Arctic is undergoing unprecedented change. Observations and models demonstrate significant perturbations to the physical and biological systems. Arctic species and ecosystems, particularly in the marine environment, ...
Impacts of Oil Spills on Arctic Marine Ecosystems: A Quantitative and Probabilistic Risk Assessment Perspective.
(2020)
Oil spills resulting from maritime accidents pose a poorly understood risk to the Arctic environment. We propose a novel probabilistic method to quantitatively assess these risks. Our method accounts for spatiotemporally ...
Trait-based approaches in rapidly changing ecosystems: A roadmap to the future polar oceans.
(2018)
Polar marine regions are facing rapid changes induced by climate change, with consequences for local faunal populations, but also for overall ecosystem functioning, goods and services. Yet given the complexity of polar ...
Computer Prediction of Seawater Sensor Parameters in the Central Arctic Region Based on Hybrid Machine Learning Algorithms.
(2020)
In recent years, with the large-scale reduction of Arctic sea ice, the supplement of chlorophyll sensor data in seawater has become an essential part of environmental assessment. Accurately predicting the chlorophyll sensor ...
Trends in Winter Light Environment Over the Arctic Ocean: A Perspective From Two Decades of Ocean Color Data.
(2020)
The last few decades have seen a decrease in Arctic ice cover, leading to changes in the structure and function of marine ecosystems. Yet sustained long-term observations of the marine environment are difficult to acquire. ...
Retrieval of Sea Surface Wind Speed from Spaceborne SAR over the Arctic Marginal Ice Zone with a Neural Network.
(2020)
In this paper, we presented a method for retrieving sea surface wind speed (SSWS) from Sentinel-1 synthetic aperture radar (SAR) horizontal-horizontal (HH) polarization data in extra-wide (EW) swath mode, which have been ...
Effect of data assimilation in the Polar WRF with 3DVAR on the prediction of radiation, heat flux, cloud, and near surface atmospheric variables over Svalbard.
(2022)
Although the Polar Weather Research and Forecasting (PWRF) model has been developed for polar environments, simulations of atmospheric states in the polar region still have large uncertainties. Therefore, the effects of ...
