The Department of Geosciences and Princeton University congratulates Brandon T. Stackhouse on successfully defending his Ph.D. thesis: "The Effects of Physical and Biogeochemical Changes on Carbon Emissions from Mineral Cryosols from the Canadian Arctic."
A concern among scientists is that higher Arctic temperatures brought about by climate change could result in the release of massive amounts of carbon locked in the region’s frozen soil in the form of carbon dioxide and methane. New research led by researchers at the Department of Geosciences and published in The ISME Journal suggests that, thanks to methane-hungry bacteria, a majority of Arctic soil might be able to absorb methane from the atmosphere rather than release it.
