Ponds and lakes receive, transport and are sites of transformation of carbon from terrestrial ecosystems. Some of that carbon is stored in the sediments, but a large portion is emitted to the atmosphere as methane (CH4) and carbon dioxide (CO2). Quantification of lake atmosphere exchange is therefore critical to understanding landscape level carbon dynamics.

The goal of this project is to quantify the effects of physical and biological controls of the exchange of carbon trace gases in a dynamic mire and lake landscape that is changing due to regional warming. The project designers hope to develop a biogeochemical understanding that can be linked to the physics via addressing the flow of carbon from land, to lakes, to exchange with the atmosphere. The project is now recruiting a student that will develop his / her doctoral research within the context of the goals of this project.

This is a cooperative project with colleagues at the University California at Santa Barbara, the State University of New York in Albany, and the Department of Geology and Geochemistry, at Stockholm University.

The joint effort reflects the interdisciplinary scope of the project that will combine elements of boundary layer dynamics, physical limnology and biogeochemistry. The program will be an intensive field measurement program, with most of the fieldwork located in northern Sweden.

Applicants should have an undergraduate degree in geochemistry, biogeochemistry, marine chemistry, chemistry, physical limnology, meteorology or similar discipline and meet the requirements for admission to the PhD program in Geochemistry at the Department of Geology and Geochemistry, at Stockholm University. The starting date is negotiable.

The application, citing the reference number SU 617-1787-08, should arrive no later than Friday, 4 July 2008. Applications should include:

- A personal letter expressing interest in the project

- Two personal letters of reference

- A resume including, name, address, telephone number, email address, education (degrees), work experience, abstracts/publications, and description of any research skills or experience

- Transcripts of all university courses and degrees

Please mail applications to:
Stockholm University
S-106 91 Stockholm

Applications via email ( or fax: +46-8-163-866 will be accepted, but must immediately be complemented by a signed hard-copy original.
