‘A realistic picture of the sea level along the coast’

At the NIOZ Sea Level Research Centre, climatologist Aimée Slangen calculates how global sea-level changes translate into effects along the coast. ‘I’m probably one of the few NIOZ researchers who never has to make fieldwork trips, because climate science is something that is mainly done behind a computer screen. For example, we receive concrete measurements of sea levels from satellites down to an accuracy of 1 mm. Then it is a question of calculating computer scenarios. However, we cannot simply translate the scenarios for the Atlantic Ocean into those for the North Sea or the Wadden Sea, because there are many regional effects. We are now trying to calculate these with an accuracy of seven by seven kilometres.’

Sand and concrete

‘In the regional sea-level scenarios for the Wadden Sea, we need to deal with factors such as soil subsidence, sand transport, wind and waves. The scenarios for the Zeeland and South Holland Delta are different, because more coastlines are protected by concrete structures, amongst other things. Due to all these different effects, we also need to try and combine many different models into a single scenario. In doing this, we now produce calculations beyond the year 2100, because large structures like dykes and delta works are not merely built for a period of twenty years.’

Living in a bathtub

‘I am currently one of the five Dutch representatives for part one of the three-part report that the United Nations climate panel IPCC will publish in 2021. This first part investigates the physical aspects of climate change. For example, we can see that the sea level rises due to the melting of glaciers and expansion of increasingly warm water, and that the contribution of the melting ice sheets on Greenland and Antarctica continues to increase. An awful lot of water is enclosed in those ice sheets. For a rich country like the Netherlands, sea-level rise can still be accommodated for a while. But at a certain moment, we will be faced with an almost philosophical question: do we want to live in the Netherlands that is a figurative bathtub – surrounded by dykes that need to be built increasingly higher? With my research, I hope to contribute to a realistic picture of what we can expect in the coming years in our delta on the North Sea.’

Research interests

I am interested in understanding and projecting (regional) sea-level changes, and on translating these to the coastal/delta/estuarine environment. I like to take a broad approach and study both global and regional sea-level changes, by include all relevant contributions. My focus is on understanding the recent past (20th century) change and projecting future changes for the 21st century and beyond.

About me

I joined the NIOZ Royal Netherlands Institute for Sea Research in January 2017. Working in the Department of Estuarine & Delta Systems (EDS), I am responsible for sea-level change research, both in the open ocean and towards the coast. I am also part of the NIOZ Sea Level Centre of expertise. I am a lead author on the forthcoming IPCC AR6 report, on the chapter on Oceans, Cryosphere and Sea Level Change. Before coming to NIOZ, I did a PhD at IMAU (Utrecht University, The Netherlands) and postdocs at CSIRO Ocean and Atmosphere (Hobart, Australia) and IMAU.

Sea levels rising ever faster according to IPCC climate report 2021
In 3,000 years, the average sea level has never risen as fast as in the last century, during which it has risen by 20 centimetres. And the sea level is rising faster and faster. Another 20 centimetres will be added in the next thirty years. If…

Exploring Sources of Uncertainty in Steric Sea‐Level Change Estimates
Ocean temperature and salinity variations lead to changes in sea level, known as steric sea‐level change. Steric variations are important contributors to sea‐level change and reflect how the oceans have been responding to global warming. For this…
