MSc thesis opportunity

At NIOZ, we are often looking for students to help us out with our sea-level research. Currently in our group we have an opportunity for a student to analyse sea-level change along the Brazilian coast, under the supervision of PhD candidate Carolina Machado.

If you are interested in this project, please get in touch: carolina.camargo[at]


Present-day sea-level change along the coast of Brazil

Project Summary

Sea-level change is not a spatially uniform process. On the contrary, regional differences from the global mean sea-level change (~3 mm/yr from 1993-2017), can be large, reaching up to 15 mm/yr depending on the study region. Thus, understanding sea-level change regionally is critical for adaptation policies.

Contrasting with the high number of studies focusing on European and North-American sea-level change, sea-level change at the coast of Brazil has been poorly investigated over the last decades. One of the reasons is the lack of data available in the region. Along the…

A new chapter in the IPCC adventure

It's been a while since my last post, and with good reason: from September to January I've been super busy writing the second order draft for the IPCC AR6 report (I'm planning to write a blogpost about my IPCC work in a while). Review for this draft will be open to experts and governments from 2 March to 26 April, so we invite everyone to have a look and provide us with feedback. 

In the mean time, I've also supervised my students, given guest lectures at Utrecht University, co-organised the NIOZ days and finished my management course.

Also, there has been some good news for my lab:

* the first paper of Tim Hermans, PhD student in my group, has been accepted for publication in Climate Dynamics

* An H2020 proposal for the PROTECT consortium I'm part of has been granted. The project focuses on the contributions of ice sheets and glaciers to sea-level change, and the coastal impacts. At NIOZ we will be hiring 1 postdoc on this project, so if you're looking for a postd…

GIA summer school

Sea level doesn’t only increase when the sea rises, but also when the land subsides! In the end, it’s all relative. To learn more about vertical land motion, Carolina and I attended the Glacial Isostatic Adjustment training school at Lantmäteriet in Gävle, the Swedish mapping, cadastral and land registration authority.
Glacial Isostatic Adjustment, or GIA for short, refers to the adjustment of the Earth to the loading and unloading of large ice sheets. The adjustment leads to land uplift underneath former ice sheets, and subsidence around its margins. Sweden has many examples of GIA: you can find beaches that have been raised to heights of 200m over the past thousands of years. Once you could swim here, but now the sea is kilometers away!
The training school held at Lantmäteriet was well organized, with very interesting lectures covering land uplift, sea-level change, geodetic observations, ice sheet dynamics and more. It was a great experience!

A day on the Navicula

On the 6th of June, Tim and me joined Long and Theo at the RV Navicula to help with a 13hr station in the Oosterschelde. Both of us being modellers, it was a good experience to board a research vessel and help to collect data. We helped out with CTDs and Niskin Bottles, to sample how the properties of the Oosterschelde change during a tidal cycle. It was a fun day and we were lucky enough to have good weather!

A Royal day

On the 20th of May, the Dutch King and Queen visited the IOW institute for Baltic Sea research in Warnemunde, Germany. On this occasion, a Letter of Intent was signed for increased collaboration between Dutch and German Oceanographic research, of which NIOZ was one of the signatories. 

Carolina en me were asked to present our work on sea-level change at the workshop that was held at IOW on the day of the visit, which was quite an honour. In the evening all workshop participants were invited to join the trade dinner. We had a great day!

1Vandaag: zeespiegelstijging in de Waddenzee

De Waddenzee is een uniek gebied in Nederland, waar zee, land en ecologie samenkomen. 1Vandaag vroeg mij naar de scenarios voor zeespiegelstijging voor de Waddenzee.
