Sea level @ NIOZ

PhD position: “Reconstructing regional sea-level change in the 20th century using observations" Yerseke , Zeeland , Netherlands         Job description New job opportunity at the Royal NIOZ: the  department of Estuarine and Delta Systems (EDS) is looking for an enthusiastic and motivated PhD candidate to address the challenge of reconstructing 20 th century regional sea-level changes. Do you want to use state-of-the-art observations and model simulations to unravel the 20 th century sea-level puzzle? Do you want to use climate models to simulate past regional sea-level changes, and close the 20 th century regional sea-level budget? We offer this 4-year position in the NWO-funded Vidi project ‘ DARSea : Detection and Attribution of 20 th century Regional Sea-level change’. The position is in the research group of Dr. Aimée Slangen, in close collaboration with Utrecht University (Department of Physical Geography). THE DEPARTMENT   The department of Estuarine and Delta Sy

  Two NIOZ researchers have receive Vidi grants of 800,000 euros. The laureates are Dr Aimée Slangen, for solving the regional sea-level puzzle and Dr Rick Hennekam, for investigating tipping points in climate and ocean systems. These grants will enable them to develop an innovative line of research over the next five years and further expand their own research group. Project DARSea: Solving the regional sea-level puzzle Sea-level change is driven by a combination of different processes, each acting on their own temporal and spatial scales. It is a complex puzzle, which has not yet been solved on a regional scale. This Vidi project will combine observations and models of regional sea-level change with a new approach to find optimal regions which allow for the puzzle to be solved. The goal is to better understand the different causes of regional sea-level change in the 20th century, which leads to better future projections.   In this Vidi project, I will use improved observations and st

Last Thursday, 15 June, Carolina sucessfully defended her PhD at TU Delft.  In the presence of her family and friends, she responded to the tough questions from the examination panel. The questions covered all aspects of her thesis, from the steric and mass contributions, to the budget and the tools used to find optimal regions.  Her thesis contains her three published papers: Exploring Sources of Uncertainty in Steric Sea‐Level Change Estimates Trends and Uncertainties of Regional Barystatic Sea-level Change in the Satellite Altimetry Era   Regionalizing the Sea-level Budget With Machine Learning Techniques   After the defense, Carolina was awarded the title of Dr!  Carolina will now move to Woods Hole Institute in the US for a postdoctoral fellowship. We are sad to see her leave and will miss her, but ofcourse we wish her lots of fun and interesting science in her next endeavours!  

Assessment of How Climate Scientists Communicate Risk Shows Imperfections, Improvements The hardest part, experts find, is communicating “unquantifiable” uncertainty Scientists have long struggled to find the best way to present crucial facts about future sea level rise, but are getting better at communicating more clearly, according to an international group of climate scientists, including Aimée Slangen from NIOZ and Tim Hermans from Utrecht University. The consequences of improving communications are enormous, the scientists said, as civic leaders actively incorporate climate scientists’ risk assessments into major planning efforts to counter some of the effects of rising seas. Writing in Nature Climate Change, the scientists review the language and graphics used in climate “assessment” reports between 1990 and 2021 by members of the United Nations’ Intergovernmental Panel on Climate Change (IPCC). “Future sea level rise emerges from a lot of different

PhD Thesis submitted! Great news! Carolina has now submitted her PhD thesis, entitled "The causes of regional sea-level change since 1993". She will defend her PhD this June.  Carolina has already landed an exciting postdoc position at Woods Hole, where she will start in July.    IPCC synthesis report It's been a pretty intense spring period, with Aimée travelling to the IPCC synthesis report approval in Interlaken in March. It was a week like no other in climate science - being part of the approval process and being on stage in front of delegates from all over the world is something else. The SPM is a great piece of text, with awesome visuals, made by an amazing and smart group of people from all working groups of the IPCC and from all over the world, and I'm honoured to have been part of the Core Writing Team. 1953 flood disaster On 1 februari 2023 it was 70 years ago that a devasting flood hit the southwest of the Netherlands. I was asked to be part of the presen

 In the past months, we have said goodbye to Tim Hermans and welcomed Jeemijn Scheen.  Tim has moved on to a postdoc position at IMAU, at Utrecht University, where he will work on projecting sea-level extremes. As he will be working in the PROTECT consortium, we will continue to work together in the coming years.  Jeemijn has come over from Bern, where she was doing her PhD at the University of Bern with Thomas Stocker. At NIOZ, she will work in the HiRise consortium, making regional sea-level projections.  In the mean time, Carolina is in the final year of her PhD and well underway to finishing her thesis. So this is our present group: Aimée, Carolina, Victor and Jeemijn. Also, two new papers have been accepted for publication: Nienhuis, J.H., W. Kim, G.A.Milne, M. Quock, A.B.A. Slangen and T.E.

It's been a while since our previous post, time for an update! First of all, Tim successfully defended his PhD and may now call himself Dr. Hermans! He will leave NIOZ and start at IMAU in Utrecht from August onwards. Very happy and thankful for getting my PhD degree yesterday, amazing end of a great journey thanks to @DrSealevel @CaroMLCamargo @LaurenWiesebron @NIOZnieuws @GRS_TUDelft and so many others!🌊🌊🎉🎊 pic.twitter.com/oQcQWycL46 — Tim Hermans (@HermansTHJ) July 8, 2022 We've also attended the WCRP sea level conference, some of the group members in real life in Singapore, some attending online. It was great to be together with the sea level community again and catch up, and we got some good feedback on our various posters and talks. In the evenings, we met up with colleagues; had a dinner with the Dutch Ambassador in Singapore, Margriet Vonno; and met with our European PROTECT colleagues. As of October we'll be welcoming a new group member for the NWO-
