Postdoc position: "The Dutch Wadden Sea as an event-driven system"

NIOZ Royal Netherlands Institute for Sea Research

Netherlands 🇳🇱

Job description


The department of Estuarine and Delta Systems research (EDS, NIOZ-Yerseke) studies how the interplay between biota, hydrodynamics, sediment dynamics and biochemistry shapes the estuarine, deltaic and coastal environments in the context of natural and human-induced environmental changes. Central to our department is a multidisciplinary holistic approach that combines state-of-the-art biophysical, biochemical, ecological, physiological measurements, remote sensing, and manipulative experiments with mathematical and numerical modelling to create in-depth understanding of the processes that control estuarine and delta systems.


The Wadden Sea is the largest back barrier tidal system in the world and a UNESCO world heritage site because of its ecological significance. A key governing component of the overall system is the exchange of water, salt, nutrients, sediment, larvae, etc. between basins and with the North Sea. Recently, we have shown that the nature of this exchange is very different than previously thought due to the dominant role of the wind, which imposes an enormous variability, with storms having a disproportionately high impact. This view of the Wadden Sea as an event-driven system means that understanding and quantifying the exchanges and transports requires the inclusion of a wide range of forcing conditions over a long time span. 

In this ENW/NWO project, we investigate the exchange between the tidal basins and the North Sea for the period 1980-2015 in the Dutch Wadden Sea.

This project is a collaboration between the Royal Netherlands Institute for Sea Research (NIOZ, Yerseke), the Department of Applied Physics at Eindhoven University of Technology, and the Leibniz Institute for Baltic Sea Research (IOW), WarnemĂĽnde, Germany.

In this position you will develop and apply new tools to quantify the exchange, the flushing characteristics of the basins, and the connectivity in the system, accounting for its event-driven character, and will analyze results of new long-term numerical simulations of the hydrodynamics to link the variability in the forcing to the exchange and transport in the region. This will provide a comprehensive view of the variability in the state of the system and in the exchanges at a wide range of time scales.
