Title Rates of relative sea-level rise during the final stage of the last deglaciation Degree of recognition International Media name/outlet Facebook Media type Social Media Country/Territory United States Date 21/03/25 Description Rates of relative sea-level rise during the final stage of the last deglaciation, the early Holocene, are key to understanding future ice melt and sea-level change under a warming climate. Data about these rates are scarce, and this limits insight into the relative contributions of the North American and Antarctic ice sheets to global sea-level rise during the early Holocene.
A team of researchers recently constructed an early Holocene sea-level curve based on 88 sea-level data points (13.7–6.2 thousand years ago (ka)) from the North Sea (Doggerland). After removing the pattern of regional glacial isostatic adjustment caused by the melting of the Eurasian Ice Sheet, the residual sea-level signal highlights two phases of accelerated sea-level rise.

Tijdens het staartje van de laatste ijstijd en de millennia daarna, tussen de 13.700 en 6.200 jaar geleden, steeg de zeespiegel met snelheden tot bijna een centimeter per jaar. Dat schrijven onderzoekers van onder meer het Nederlandse kennisinstituut Deltares deze week in Nature. De periodes met extra snelle stijging werden veroorzaakt door het smelten van de Noord-Amerikaanse en Antarctische ijskappen. Die snelheden geven een inkijkje in wat ons de komende eeuwen mogelijk te wachten staat.Producer/Author NRC/Gemma Venhuizen URL https://www.nrc.nl/nieuws/2025/03/20/na-de-laatste-ijstijd-steeg-de-zeespiegel-elk-jaar-een-centimeter-en-verdween-doggerland-a4887047 Persons Marc Hijma, Kim Cohen Title Wetenschappers vinden bewijs voor extreme zeespiegelstijging na laatste ijstijd Degree of recognition National Media name/outlet NU.nl Media type Web Country/Territory Netherlands Date 19/03/25 Description Wetenschappers hebben ontdekt dat de zeespiegel vlak na de laatste ijstijd snel steeg.

Title Hoe snel steeg de zeespiegel na de laatste ijstijd? Degree of recognition National Media name/outlet UU.nl/niews Media type Web Country/Territory Netherlands Date 20/03/25 Description Dankzij een unieke dataset uit de bodem van de Noordzee kunnen we de zeespiegelstijging van vlak na de laatste ijstijd aanzienlijk nauwkeuriger in kaart brengen. In die periode, vanaf 11.700 jaar geleden, steeg de zeespiegel in een snel tempo door de opwarming van de aarde en het smelten van de enorme ijskappen die toen grote delen van Noord-Amerika en Noord-Europa bedekten. Iedere eeuw weer stond het waterpeil een meter of wat hoger. Uit die geschiedenis kunnen we belangrijke lessen trekken: voor het begrijpen van snel smeltende ijskappen bij opwarming destijds, en daarmee ook voor het testen van modellen die moeten beschrijven hoe een toekomstige zeespiegelstijging zich zal voltrekken. De gegevens uit de Noordzeebodem zijn verzameld door een groep onderzoekers instituten in binnen- en buitenland, waaronder Deltares, Universiteit Utrecht, NIOZ en TNO Geologische Dienst Nederland. De resultaten zijn vandaag gepubliceerd in het gerenommeerde vaktijdschrift Nature.

Degree of recognition International Media name/outlet UU.nl/en/news Media type Web Country/Territory Netherlands Date 20/03/25 Description After the last ice age, some 11,700 years ago, sea levels rose rapidly due to global warming and the melting of the huge ice sheets that covered large parts of North America and Europe. During the early Holocene, the period after the last ice age, sea levels rose by about one metre a century at some stages. This rapid rise is seen as an important reference point for predicting future sea level rise, particularly now when we are seeing a similar situation with rapidly melting ice sheets due to global warming.

Degree of recognition International Media name/outlet LinkedIn Pulse Media type Social Media Country/Territory Netherlands Date 20/03/25 Description Thanks to a unique dataset collected from the bottom of the North Sea, we can reconstruct sea level rise that occurred after the last ice age considerably more accurately. During this period, some 11,700 years ago, sea levels rose rapidly due to global warming and the melting of the huge ice sheets that covered large parts of North America and Europe. This rapid rise is seen as an important reference point for predicting future sea level rise, particularly now when we are seeing a similar situation with rapidly melting ice sheets due to global warming. The data from the North Sea bed were collected by a group of researchers institutes in the Netherlands and abroad, including Deltares, Utrecht University, NIOZ and TNO Geological Survey of the Netherlands.

Degree of recognition National Media name/outlet TNO news room Media type Web Country/Territory Netherlands Date 19/03/25 Description Until now, the rates and extent of sea level rise during the early Holocene were poorly understood because of a lack of sound geological data from this period. Researchers from Deltares, the Netherlands Organisation for Applied Scientific Research (TNO) and, among others, Utrecht University, Delft University of Technology, the Netherlands Institute for Marine Research, Wageningen University and Research and the University of Amsterdam have now been able to draw on a unique dataset from the North Sea region to make highly accurate estimates of sea level rise in the early Holocene for the first time.
