PhD student Álvaro Del Rey and MSc Julius Havsteen participated in the Uranium Biogeochemistry Conference in Ascona (Switzerland). Results from Julius’ thesis were presented at the poster session Wednesday afternoon, which put forward new constraints on the global oxygenation state of the Late Silurian ocean and discuss the use of brachiopods instead of bulk carbonate samples […]
Our group will give several presentation at the Nordic Winter Meeting at DTU in Lyngby, Denmark Wednesday Jan 10, 2018 10.00-11.00 Student poster presentations Magnus A. R, Harding “Surface analyses of fossil leaves” Julius C. Havsteen “The Silurian Lau event – testing plant weathering as driver for ocean anoxia and animal extinction” Thursday Jan 11, […]
Beginning in January 2018, Magnus A. R. Harding will continue working in the group now as a research assistant. Magnus’ main focus will be to extend ongoing studies of the chemical composition of fossil plant leaves.
A new paper on the redox conditions in the oceans after the Sturtian and before the Marinoan ‘Snowball’ glaciations is now press in Precambrian Research. Our results suggest that oceans remained largely anoxic after the Sturtian glaciation and that something else triggered oxygenation of the Ediacaran oceans after the Marinoan glaciation. This ‘something’ could be due to the way animals affect the global […]
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 […]
