New study on the oceanic conditions of the last glacial period

Professor Marit-Solveig Seidenkrantz and assistant professor Christof Pearce show in the study that there was a stronger influx of Atlantic Water into the Labrador Sea region than today during the Last Glacial Maximum (23-19,000 years ago), suggesting a much more vigorous North Atlantic Ocean circulation than previously assumed.

Goodbye to Delphini-1

On Sunday 14 March 2021, the student satellite Delphini-1 from Aarhus University burned up in the atmosphere after a long period of faithful service. The satellite stayed up for quite a bit longer than expected. The project has been a great success with many involved from various Departments at Aarhus University, including Geoscience. Read more.

Danish students will launch their own satellite next summer

The satellite will be launched on a Falcon-9 rocket in the Summer of 2022. The satellite will include a number of smaller student experiments as well as serve as a communications station for radio amateurs around the world. Christoffer Karoff from the Department of Geoscience is part of the project.

New studies support that agricultural lime affects strontium analyzes

Erik Thomsen and Rasmus Andreasen from the Department of Geoscience demonstrate in two new scientific articles that strontium from agricultural lime is leached from the upper soil layers and thus affects the strontium isotope values in the environment. Thus, a number of hypotheses about the origins of prehistoric humans should be revised.

Hadal trenches are dynamic hotspots for early diagenesis in the deep sea

Professor Sanei in collaboration with an international research team have explored sediment characteristics and in-situ benthic oxygen uptake along two trenches in the Pacific Ocean. They have concluded that hadal trenches represent deep sea hotspots for early diagenesis and are more diverse and dynamic environments than previously recognized.

Mysteries of organic matter in the 120-million-year old rocks of the Danish North Sea

The secrets of how organic matter got into the rocks, its evolution, and what role it may play in storing energy and greenhouse gases are now unraveled, thanks to the new research conducted by Arka Rudra, Hamed Sanei, Carlette Blok, and Stéphane Bodin of the Department of Geoscience in collaboration with GEUS.
