Scientists share multidisciplinary discoveries at 'Earth System Processes'

J. Bjerrum, Danish Center for Earth System Science at the University of Copenhagen, will postulate that due to the limited availability of phosphorous, a principle nutrient in limiting carbon production, photosynthesis was depressed in cyanobacteria during the Archean and early Proterozoic.
  • Christopher House, a microbial geobiologist from Pennsylvania State University, will provide further evidence for a newly discovered archaeal bacterial lineage that consumes methane anaerobically. He gathered this evidence using FISH and iron microbe techniques to measure carbon isotope depletion.
  • Martin Brasier, Earth Sciences at the University of Oxford, will provide a new look at whether or not morphological remains of fossils thought to be photosynthetic are as old as previous estimates have stipulated. This is important as it is some of the most quoted evidence for the antiquity of oxygenic photosynthesis.
  • Janet Siefert will present data that uses some of the most basic molecules for biochemistry, iron-sulfur clusters, to determine the sequence of metabolic events that may have occurred in the Archean timeframe.
  • George Fox, Department of Biology and Biochemistry at the University of Houston, will give a genomic perspective of what the Archean contemporary cyanobacteria must have contained as its genomic component. This is an important piece of molecular evidence that can be compared to the morphological fossil record and the proposed atmospheric conditions prior to the rise of oxygen.
