Thesis Methane distribution in the water column of a Thermokarst Lake
Background and Tasks
Research Division: Shelf Sea System Ecology & Periglacial ResearchMethane and carbon dioxide are prominent greenhouse gases. Especially arctic lakes are estimated to contribute to a large extent to the increasing atmospheric concentration of methane in the arctic. However, the details of the methane cycle in such thermocarst lakes are not well known, yet. Therefore, in a holistic approach, several working groups will focus on one thermocarst lake in Siberia trying to understand the different processes forming this lake and its carbon turnover. Our group will focus on the distribution of methane in the water column under ice or open water and try to verify which sedimentary structures result in increased methane concentrations.
With a cavity ring-down spectroscopic instrument we will measure methane concentration in high spatial resolution in spring and summer conditions.
Requirements
- Experience in gas analysis
- Experience data analysis (such as R)
Additional skills and knowledge
- Ability to participate in field trips to Siberia
