MSc student in Geology, University of Copenhagen
My main interests within geology are geobiology and geochemistry. Geobiology is the study of how all the living (the biosphere) interacts with all the non-living (the geosphere, the atmosphere and the hydrosphere). Geochemistry is one of the main tools used to study patterns and cycles within geobiology. What I find very interesting about geobiology is, that it tells the story of the coevolution between life and Earth. For example, is it due to an at least 2.4 billion years old evolutionary innovation (oxygenic photosynthesis) that the atmosphere contains free oxygen today. It is such evolutionary revolutions that has subsequently shaped both the evolution of life and the planet. In my master’s thesis I investigate a 420 million year old climatic event – the Silurian “Lau event” and study how the emergence of vascular plants might have affected the oxygenation state of the Silurian oceans. To constrain this, I use stable uranium isotopes.
