PhD Defence | September 8 | Martha Kosters
Free access, but don't be late! In case a layman’s talk is included in the ceremony, this will start 15 minutes ahead of the time that is announced below!

On Tuesday September 8th at 10.15h, Martha Kosters will defend her dissertation 'Micromagnetic Tomography: Insights from a single Hawaiian basalt'. Her (co-)promotores are Prof. Wout Krijgsman and Dr Lennart de Groot.

Paleomagnetism is the art of retrieving the direction and intensity of the Earth Magnetic Field from rock samples of varying ages and locations. This data can be used for a wide variety of Earth Scientific purposes, from reconstructing plate tectonics to modeling the geodynamo. Micromagnetic Tomography (MMT) is a newly developed technique to retrieve the magnetic signal from individual magnetic grains using a Quantum Diamond Microscope (QDM).

Go-ahead for monitoring well for underground heat storage at the Utrecht Science Park

Utrecht University is taking an important step towards making its energy supply more sustainable. The Executive Board has given the go-ahead for the next phase of the high-temperature thermal storage (HTS) project. During this phase, a monitoring and exploration well will be installed to further map the characteristics of the subsurface.

npj CLEAN WATER | Rising competition for clean water in the future.

Water scarcity is not just a matter of a lack of supply. What if there is enough water available, but its quality leaves much to be desired? And what if the interests of the various sectors - households, agriculture, industry and energy producers - also clash with each other? In a large overview study, Utrecht researchers are the first to provide an overview of these different interests, broken down by region, and of the deficits that lurk with unchanged policy. "Because otherwise, by the end of this century, almost two-thirds of the world's population will have to contend with too little water or poor quality water." They therefore argue for firmer policy. "In the end, it's not just about how much water is available, but also whether it has the right quality for its intended use."

NATURE GEOSCIENCE | Geological evidence questions the role of Agulhas Leakage in Atlantic Ocean Circulation.

For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contribution to the Atlantic Meridional Overturning Circulation (AMOC), a component of the global ocean conveyor system. New research led by an international team from the Netherlands, USA, China and UK suggests that the mechanism linking leakage of Indian Ocean water and deep-water formation was and is not as straightforward as previously thought. This research contributes to a better understanding of the AMOC, a key regulator of the Earth’s climate.

NATURE GEOSCIENCE | Triassic Inferno: Fires raged across Europe for thousands of years during past global warming.

The end-Triassic mass extinction, 201 million years ago, is linked to volcanism that resulted from the break-up of Pangea and which pumped out vast amounts of CO2 into the atmosphere causing extreme global warming of 5 to 10 degrees Celsius. As a result, tree-dominated vegetation collapsed and the highly disturbed landscapes were colonized by ferns that formed savannahs across large swaths of what is now Northwest Europe. New research by an international team led by earth scientists from Utrecht University has found that these fern savannahs were prone to large-scale burning, whereby the ferns themselves acted as the fuel that fanned the flames.

It's 50 years after Viking 1 landed on Mars! Read the interview with Inge Loes ten Kate here:

Exactly 50 years ago today, Viking 1 landed on Mars. The spacecraft was part of the only mission ever to have searched for extraterrestrial life. With calls growing for humans to be sent there too, astrobiologist Prof. Inge Loes ten Kate is calling for a new unmanned life-detection mission.

Two NWO-veni-grants awarded in the Faculty of Geosciences!

Today, NWO announced 205 laureates for the veni-grants in the 2025 application round. Among these are Melanie During and David Gold.

Melanie will start her project 'Was the last mass extinction less severe in the Southern Hemisphere?' as a postdoc in the department of Earth Science, in the group of Douwe van Hinsbergen.

David is assistant professor in the department of Physical Geography. His project is called 'Integrated Multi-Risk Decision Support for Climate-Resilient Water Systems'.

An overview of all 205 laureates. including small project summaries, can be found on the website of NWO:
