Post-doctoral Fellow Job Announcement: Tidal Wetland Ecosystem Process Modeler
Smithsonian Environmental Research Center, and Oak Ridge National Laboratory

Position Summary: Tidal wetland ecosystem process modeler exploring water, 
carbon, and nutrient interactions with experimental warming and elevated CO2.

Details:
A postdoctoral research position is available, working with an 
interdisciplinary team on an exciting new manipulative experiment that examines 
the interactions of warming, elevated CO2, and inundation frequency in coastal 
wetland marsh ecosystems. The position focuses on the development, application, 
and analysis of new computational models that couple energy, water, carbon, and 
nutrient dynamics in tidal wetland systems. This new position will collaborate 
as part of an active modeling team and will be expected to interact closely 
with the teams of researchers working in the field.

The project focuses on a unique manipulative experiment located at the 
Smithsonian Environmental Research Center (SERC) in Edgewater, MD. The 
manipulative experiment is already underway, and both pre- and post-treatment 
results are now available for use by the modeling team. A broad array of 
measurements is being gathered routinely, including marsh height, water levels, 
meteorological conditions, vegetation community distribution and productivity, 
plant traits, soil biogeochemistry, and CO2 and CH4 fluxes. Thanks to a long 
history of research at the site, a wealth of observational and experimental 
data is available to inform model construction and to evaluate model 
performance. The primary objective of the study is to test the hypothesis that 
warming will increase both plant production and decomposition, but that the net 
effect will be an increase in soil carbon storage.

This position will work directly with the land model component of the new 
Department of Energy Earth System Model. The full model is known as ACME 
(Accelerated Climate Model for Energy), and the land component used as a 
starting point for this activity is the ACME Land Model (ALM) version 1.0. That 
model includes sophisticated carbon, nitrogen, and phosphorus biogeochemistry 
and vegetation physiology, but has never been enabled for simulation in a tidal 
wetland system. New development led by this position will include introduction 
of redox and pH controls on soil biogeochemistry (some early work is available 
as a starting point), introduction of external forcing for water height to 
mimic tidal variation, and parameterization of high marsh and low marsh 
physical environment and vegetation community. The new position will have 
excellent opportunity for creative freedom to explore alternative approaches 
and to design the most effective interactions with observational and 
experimental project elements.

A strong background in computational modeling is a requirement, with experience 
in land, wetland, or tidal system modeling desirable. A demonstrated record of 
scientific productivity and strong written and oral communication skills are 
also required for this position. Experience collaborating with 
observationalists and experimentalists is highly desirable. The ALM v1.0 model 
uses Fortran90, and so Fortran experience is desirable, but not necessary.

This is a two-year position funded by SERC, but the successful candidate will 
work at the Climate Change Science Institute at Oak Ridge National Laboratory, 
located in the lush temperate forest biome near Knoxville, in eastern 
Tennessee. Abundant local recreational opportunities include hiking, biking, 
camping, and wildlife observation, in the Tennessee River valley, in the Smoky 
Mountains to the east, and on the Cumberland Plateau to west. Numerous rivers 
and lakes provide abundant opportunity for all sorts of boating and fishing. 
Regular visits to interact with project members and measurement activities at 
the experimental site in Maryland will be expected, with all travel expenses 
covered by the project.

To apply, please e‐mail a short letter of interest that describes your 
experience and qualifications (1‐2 pages), CV, and list of references by 1 Dec 
2016 to Dr. Patrick Megonigal (<megonigalp@si.edu>). Review of applications 
will begin immediately, and the search will continue until a suitable applicant 
is found. The candidate is expected to start between January and March 2017. 
Questions about this position can be directed to Peter Thornton
(<thorntonpe@ornl.gov>) or Patrick Megonigal.
