Biogeochemistry and Oxygenic Photosynthesis
February 8, 2007 / Posted by: Shige Abe
Researchers from NAI’s University of Colorado, Boulder Team recently reported in Earth and Planetary Science Letters their new biogeochemical model relating to the Great Oxidation Event. With ion microprobe data for individual sulfides from water-lain sedimentary units in the 2.45–2.22 Ga Huronian Supergroup, the team proposes a new model where enhanced weathering rates during interglacial thawing stimulated blooms of oxygenic photosynthesis, the demise of methane, and ultimately the irreversible rise in atmospheric oxygen between the first and second Huronian glaciations. The paper’s lead author was also the recipient of an NAI Research Scholarship in 2004.
