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 […]

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 […]

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, […]

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 […]

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.

Article in PNAS: Humble moss created modern O2 levels

In a new modeling study led by Tim Lenton from University of Exeter, we found that the earliest land plants caused atmospheric O2 levels to increase above the “fire limit”, where stuff will ignite and burn. This result fits nicely with available geochemical and paleontological evidence, but previous theoretical models predicted either an earlier or a later rise of […]

Outreach: Lundbeck Foundation sponsors “Microbial World and the Evolution of Life”

Inspired by the Boston Science Club for Girls, the Young Academy under the Royal Danish Academy of Sciences and Letters, have initiated a new mentor program for primary schoolers called “Videnskabsklubben” (The Science Club). The Science club creates a program for enthusiastic children, who wish to explore the natural world. Junior mentors from 8th-9th grade act as junior mentors […]

Eva enrolls as Summer Undergraduate Research Fellow at Caltech

Eva will be working on her own research project on Mg(2+)-Fe(2+) zonation in olivine minerals using X-Ray Diffraction (XRD). This may allow for reassessment of olivine minerals found on Mars’ surface. Prof. Ed Stolper will serve as advisor in this SURF project. Eva returns to Copenhagen on September 1.
