I have been awarded a fellowship from the Deep Carbon Observatory's Deep Life Modeling and Visualization program, to support research investigating the energy fluxes and carbon transformations in deep ocean sediments. Super grateful to the organization , supported by the Alfred P. Sloan Foundation, for funding this important work.
Having worked a couple of seasons at 78° north in the High-Arctic (Svalbard), I am currently 78° south of the equator, only 850 miles from the South Pole. I'm is part of an international team of researchers investigating the microorganisms that tolerate (dare I say thrive) the extreme conditions of the Ross Sea and surrounding region.
The annual meeting of the American Geophysical Union (AGU) takes place in New Orleans this year. Catch my invited presentation in session B11A: Bioenergetics as a Driver of Biogeochemical Processes and Cycling, on Monday. I've calculated the importance of various energy sources in keeping alive some ancient microorganisms buried in multi-million year-old sediments underlying the South Pacific Gyre.
