Tidal river plumes dominate many shelf seas, transporting freshwater, sediment, nutrients, pollutants and larvae downstream. The Rhine River Plume is one of the largest in Europe, under typical discharge conditions it is dominated by tidal plume fron

In the face of climate change and changing sea levels, it is important to understand the different drivers of sea-level variability. Tides and atmospheric forcing are the major drivers of sea-level variability, while steric contributions are often ne

The position and properties of a river plume strongly depend on the wind conditions. Upwelling-favourable winds force the plume offshore, while the freshwater layer thins. Downwelling-favourable winds confine the plume against the coast, resulting in

A study by Afrasteh et al. (2021) has shown that combining model-based hydrodynamic leveling data with data of the Unified European Leveling Network (UELN) has great potential to improve the quality of the European Vertical Reference Frame (EVRF). In

Satellite observations can help in the retrieval of constituents in shallow waters. Noise contamination, however, makes smaller constituents irretrievable and large sources of error. Throughout shallow areas, the constituent’s relevancy changes. Fo

Model-based hydrodynamic leveling allows transferring heights between tide gauges by means of model-derived mean water level (MWL) differences between them. In this study, we aim to exploit the technique to improve the quality of the European Vertica

Tidal constituents obtained from satellite radar altimeter derived water levels are widely used for ocean-related applications. However, in coastal waters, the tidal signal's complexity increases due to non-linear interactions between tidal constitue

The sound speed provides insight in ocean properties, as it depends on depth, temperature and salinity. Here, we propose a method to invert sound speed profiles (SSPs) from multibeam echosounder (MBES) measurements, providing a SSP for every ping. Us

The Rhine River discharges freshwater into the North Sea, forming one of the largest Regions of Freshwater Influence (ROFI) in Europe. Every tidal cycle, a freshwater lens is released. These fronts were captured by the STRAINS (STRAtification Impacts
