Postdoctoral Position in Trace Metal Biogeochemistry 
Smithsonian Environmental Research Center


A two year Postdoctoral Fellowship is available at the Smithsonian
Environmental Research Center to study the mercury biogeochemistry as part
the METAALICUS project. The Mercury Experiment to Assess Atmospheric Loading
in Canada and the United States (METAALICUS) project is a whole-watershed Hg
loading experiment being conducted in Lake 658 at the Experimental Lakes
Area (ELA) in northwestern Ontario. The METAALCUS team, a multidisciplinary
team of researchers from the U.S. and Canada, designed the study to test the
response of ecosystems to changing mercury deposition. The L658 watershed,
labeled over the last 7 years with atmospherically-relevant loads of
traceable, enriched stable Hg isotopes, provides a one-of-a-kind chance to
study the fate of Hg in watersheds and aquatic ecosystems.

The Postdoctoral Fellow will be expected to develop and lead a project on
the complexation and bioavailability of Hg within the L658 ecosystem, with a
focus on the interactions between mercury and dissolved organic matter.
Broad opportunities exist to examine the biogeochemical controls on
retention and transport in the L658 watershed, to study the bioavailability
of Hg in the L658 system for methylation, and/or to study microbial mercury
uptake mechanisms. 

A Ph.D. in biogeochemistry or a related field (e.g. Microbial Ecology,
Environmental Chemistry) is required. Research experience in either 1) the
biogeochemistry of DOC and/or trace metals or 2) the uptake of trace metals
by microorganisms is required. Analytical and field experience is preferred. 

The available position is funded through a 3 year grant from the NSF to A.
Heyes and C. Gilmour.  Smithsonian Postdoctoral Fellows receive an annual
stipend of $42,000 plus health benefits and limited relocation expenses.
Start date is as soon as is possible, with the hope that the Fellow would be
in place for the 2009 field season. This position will be based at SERC but
will involve significant travel to the Experimental Lakes Area (ELA) during
the field season. 

Please provide a CV and a statement of your research interests, including a
brief statement of your potential research direction. For non-US citizens,
please include citizenship, country of Permanent Residence, date and place
of birth, type of Visa if currently in the U.S., and length of time on
current visa. The Smithsonian Institution is an equal opportunity employer.
