MSc Geology student Julius C. Havsteen starts his thesis project in January 2018, where he will be exploring changes in the the globally integrated ocean oxygenation state during the Silurian Lau event. The Lau event is the largest carbon isotope excursion in the Phanerozoic, recording a brief period of dramatic changes in the Earth system. Nevertheless, the driving … Read More

Welcome to PhD student Alvaro Del Rey
On September 1, Alvaro del Rey joined the lab as a PhD fellow in geobiology and experimental isotope geochemistry. Alvaro has a background in igneous petrology and will now be working on uranium isotopes in carbonate rocks during Mid-Paleozoic events.
Publication: Molybdenum interacts directly with organic matter in sulfidic environments
Molybdenum is one of the most powerful elements used to track hydrogen sulfide and oxygen in the ocean from the geological record. Still, we have an incomplete understanding of the chemical removal pathway between ocean and sediments. Sediments deposited under anoxic and sulfidic waters display tight correlations between their contents of molybdenum (Mo) and total organic matter (TOC). Yet, association does not mean causation. Instead, … Read More
Dr. Li Da is visiting from Nanjing University
Dr. Li Da is visiting the our research group to carry out isotope analyses of approx. 525 million years old limestone from China. These limestone comes from the Cambrian explosion, a period of approx. 540-520 million years ago, when skeletonized, marine animals suddenly diversified into new species. The study will compare the stable isotopic composition of uranium deposited in a Chinese … Read More
Outreach video: Bioturbation and the rise of animals
As part of his MSc thesis work, Sune explores how worms digging in mud affect seawater chemistry. You can now join us in the field by watching the movie produced by Underground Channel.
