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 […]
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.
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 […]
IGCP 653 conference on “The onset of the Great Ordovician Biodiversity Event” at Durham University Sunday, 25 September 2016 – Saturday, 1 October 2016 More info: www.igcp653.org Registration
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 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.
Tais will present isotope evidence for a brief oxygenation episode during the Cambrian explosion of animal life 520 Myr. The event reflects a reorganization of Earth’s global biogeochemical cycles driven by faster biological pump. One explanation is that animals themselves accelerated the transport of organic matter out of the oceans and into the sediments; for example as a result of creating larger faecal pellets, […]

Tais speaks at the workshop on molybdenum biogeochemistry in Stockholm, arranged by Swedish University of Agricultural Sciences and Swedish Nuclear Fuel and Waste Management Company.
