Relative dispersion and relative diffusivities in an ocean-wave coupled model of the North Sea Open
The study analyzes the impact of various wave-induced processes on relative dispersion and diffusivities in the North Sea using OpenDrift, a Lagrangian particle-drift model driven by a fully coupled NEMO-WAM model. The coupled model parame…

Sources, pathways, and abatement strategies of macroplastic pollution: an interdisciplinary approach for the southern North Sea Open
The issue of marine plastic pollution has been extensively studied by various scientific disciplines in recent decades due to its global threat. However, owing to its complexity, it requires an interdisciplinary approach to develop effecti…
Numerical modelling of extreme wave events in the Southwestern South Atlantic Open
Severe ocean surface waves generated by wind (hereafter waves) have a strong impact on socio-economic activities such as navigation, harbours, oil exploitation, and coastal infrastructure. The South Atlantic monitoring remains behind regar…

Relative dispersion and relative diffusivities of model-runs in the North Sea Open
We examined the relative dispersion and relative diffusivities of model-runs in the North Sea for the period Oct-Dec 2018 and Jan 2019. The role of the different wave-induced processes is investigated using a fully coupled (NEMO-WAM) model…
Long-term interannual changes in extreme winds and waves in the Black Sea Open
This study aims to analyse long-term interannual changes in extreme winds and waves in the Black Sea. Severe wave conditions from 1979 to 2020 are detected using the 99th percentile of the significant wave height (SWH), based on the method…
Monitoring and Forecasting the Ocean State and Biogeochemical Processes in the Black Sea: Recent Developments in the Copernicus Marine Service Open
The Black Sea Monitoring and Forecasting Center (BS-MFC) is the European reference service for the provision of ocean analyses, forecasts, and reanalyses in the Black Sea basin. It is part of the Copernicus Marine Environment and Monitorin…

Effects of Wave-Induced Processes in a Coupled Wave–Ocean Model on Particle Transport Simulations Open
This study investigates the effects of wind–wave processes in a coupled wave–ocean circulation model on Lagrangian transport simulations. Drifters deployed in the southern North Sea from May to June 2015 are used. The Eulerian currents are…

Lagrangian Methods for Visualizing and Assessing Frontal Dynamics of Floating Marine Litter with a Focus on Tidal Basins Open
Lagrangian methods are a common tool in physical oceanography. Due to the quasi-Lagrangian characteristics of floating marine litter (FML) and the chemical substances released from it, Lagrangian methods can be used to study this environme…
Numerical Eddy-Resolving Modeling of the Ocean: Mesoscale and Sub-Mesoscale Examples Open
Purpose. The study addresses rotational motion of geophysical fluids in the horizontal and vertical planes. It is aimed mainly at tracing the development of high-resolution numerical modeling of the ocean, as well as at demonstrating new p…

Relative Dispersion of Surface Drifters in the North Sea: The Effect of Tides on Mesoscale Diffusivity Open
We examine the relative dispersion and the contribution of tides on the relative diffusivities of surface drifters in the North Sea. The drifters are released in two clusters, yielding 43 pairs, in the vicinity of a tidal mixing front in t…
Circulation of the European northwest shelf: a Lagrangian perspective Open
The dynamics of the European northwest shelf (ENWS), the surrounding deep ocean, and the continental slope between them are analysed in a framework of numerical simulations using Lagrangian methods. Several sensitivity experiments are carr…
Interactions between barotropic tides and mesoscale processes in deep ocean and shelf regions Open
The interactions between barotropic tides and mesoscale processes were studied using the results of a numerical model in which tidal forcing was turned on and off. The research area covered part of the East Atlantic Ocean, a steep continen…
