John Kessler

Dr. John Kessler Ph.D. Earth System Science Dr. Kessler is a chemical oceanographer who focuses onisotope biogeochemistry to eluciade how gases in the ocean cycle and ultimatelyparticipate in global climate change. He is particularly interestedin oceanic methane which, due to the dynamic nature and massive size of therelatively unexplored oceanic methane system, has the potential for feedbackswith climate. Dr. Kessler's research strives to quantify sources,sinks, and fluxes of oceanic methane using analytical chemistry measurementswith particular emphasis on stable and radiocarbon isotopes.
