In a paper published in Chemical Geology entitled: “Molybdenum isotope fractionation and speciation in a euxinic lake—Testing ways to discern isotope fractionation processes in a sulfidic setting”, we compare molybdenum isotope and speciation data from lake sediments deposited under euxinic (anoxic and sulfidic) waters. We conclude that the chemical Mo species present in sediments did not … Read More

Call for applications: PhD in geochemistry / geobiology. Deadline April 30
The project is to study how the invasions of land plants influenced the oxygenation state of Earth’s oceans. The project will include experimental geochemistry (laboratory work), field work and geochemical modelling. Check out the official call here: We are looking for a self-driven student with a background in experimental geochemistry (or equivalent) and a strong motivation to conduct research in Earth history. Please … Read More
Molybdenum review: The answer is 42
Molybdenum is element number 42 in the periodic table. Although, this element is a trace constituent in the Earth and life, it currently deserves a lot of attention. With Brian Kendall and Ariel Anbar, I have written a review that brings the latest update on the various aspects of molybdenum isotopes and their current use in geochemistry, cosmochemistry and … Read More
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.
