*Postdoctoral Position at the University of Arizona and Biosphere 2*

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. This is a
one-year position with the possibility of renewal.

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,
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.

The candidate will manage cutting edge trace gas and stable isotope
instrumentation, deployed at Biosphere 2, lead interpretation of data
collected from the hundreds of sampling locations in LEO, and work as part
of a multidisciplinary team studying the co-evolution of biotic and abiotic
features of landscapes. The candidate will add new measurement capabilities
to the LEO system, which will involve the construction of new systems for
gas flow, calibration, and data collection and their automation. The
position is based at University Arizona, but will involve significant time
commitments at Biosphere 2. These requirements will provide exceptional
opportunities to learn new techniques and to make major scientific
contributions to problems of both scientific and societal interest using
cutting-edge technology.
