Dietary and seasonal variability in trophic relations at the base of the North Sea pelagic food web revealed by stable isotope and fatty acid analysis
(Journal article; Peer reviewed, 2018-11)A two-dimensional biomarker approach including fatty acids and stable isotopes of seston and copepods was applied to examine how the variability at the base of the food web affects trophic interactions between primary ... -
Different topologies of natural vortex dislocations in Mode A wake
(Peer reviewed; Journal article, 2022)The mode A wake behind a circular cylinder at Reynolds number 200 was simulated by directly solving the three-dimensional Navier–Stokes equations. A more detailed investigation of different topologies of natural vortex ... -
Direction, not detail: Progress towards consensus at the fourth intergovernmental conference on biodiversity beyond national jurisdiction
(Peer reviewed; Journal article, 2022)After a two year delay caused by the COVID-19 pandemic, the fourth intergovernmental conference (IGC-4) in the negotiations for a new UN treaty to address the conservation and sustainable management of biodiversity beyond ... -
Directional wave spectrum estimation with ship motion responses using adversarial networks
(Peer reviewed; Journal article, 2022)The external environmental conditions around a vessel are essential for efficient and safe ship operation, among which the sea state is of key importance. Considering the ship as a large wave buoy, the sea state can be ... -
Discrimination between weaned and unweaned atlantic cod (Gadus morhua) in capture-based aquaculture (CBA) by X-ray imaging and radio-frequency metal detector
(Journal article; Peer reviewed, 2014-04-17)The aim of this study was to investigate the feasibility of two detection methods for use in discrimination and sorting of adult Atlantic cod (about 2 kg) in the small scale capture-based aquaculture (CBA). Presently, there ... -
