PhD position on Effect of Arctic and Antarctic changes on coastal sea level extremes

Updated: about 2 months ago
Deadline: 02 Nov 2021

To strengthen our new 'Dutch Polar Climate and Cryosphere Change Consortium' or DP4C project team we are looking for a PhD candidate. DP4C is a multi-disciplinary project funded by NWO as as part of the Netherlands Polar Programme policy-driven research funding. It is led by Prof. Roderik van der Wal of Utrecht University in close collaboration with Groningen University, VU Amsterdam, NIOZ, KNMI, Deltares and TU Delft.

Climate change is amplified in polar regions, with sea-ice and ice sheets retreating and thinning. In fact, climate change in polar regions is profound and changes are accellerating. Changes in polar regions will not only be felt there, but also impact the Netherlands. Most prominently extreme sea level events will increase in frequency due to an increase in relative sea level which is largely driven by the mass loss of land ice. As a result, coastal risks will increase strongly if no further adaptation measures are taken. The DP4C project aims to further our understanding of the cryosphere and its changes and translate these results to the implications for the Dutch coast. It aims to contribute to research on sea ice changes (P1),ocean circulation in the Arctic (P2), changes in Greenland and Antarctica (P3 and P4), mass loss observations from space (P5), relative sea level (P6) and extreme sea level events (P7).

Position at EEMCS/DIAM (P7): The aim of this part of the project is to translate how observed and modelled changes in the cryosphere affect storm surges and extreme

sea-level along the coasts, especially the Dutch coast. You will develop improved global projections of extreme sea level, using the latest version of our Global Tide Surge Model. This requires an new parametrization of the air-sea momentum transfer under ice-coverage, which is very variable and critical to simulate storm surges. Further improvements are expected from new climate model results and updated estimates from P1 and P6. Finally, you will identify exceptional events and explore what are possible tales of future weather, exploring physically plausible what-if scenarios for the Dutch coastal safety.

The PhD candidate will be supervised by Prof. Martin Verlaan and Dr. Sanne Muis
