Organization: Biosphere 2 – University of Arizona
Duties: The postdoc will take a leadership role in evaluating a suite of carbon cycle tracers including carbonyl sulfide (COS), oxygen isotopes of CO2 (18O-CO2), and solar induced fluorescence (SIF). Photosynthesis cannot be directly measured at the ecosystem or global scale; thus independent tracers for photosynthesis are needed to reduce uncertainty in the responses of photosynthesis and respiration to global change to better project biosphere-atmosphere feedbacks. Carbon cycle tracers will be evaluated at Biosphere 2’s flagship research infrastructure, the Landscape Evolution Observatory (LEO, http://biosphere2.org/research/projects/landscape-evolution-observatory), which is the world’s largest laboratory experiment in the interdisciplinary Earth sciences and boasts an unrivaled capability to close water, carbon, and energy balance at the landscape scale. The cycling of these tracers in LEO and the B2 biomes (rainforest, desert, savanna, mangrove, ocean) will be compared to relevant genomic traits in leaves and soils.
Desired qualifications: Biosphere 2 is looking for a creative post-doctoral scientist with a strong background in instrumentation and isotope and/or trace gas biogeochemistry to join an interdisciplinary “ecosystem genomics” team seeking to link biotic and abiotic processes from pores to the ecosystem scale.
Application deadline: Application review begins March 1, 2017.
