Understanding climate change requires knowledge of climatic effects on global carbon (C) cycling in coupled land-water-atmospheric systems. One aspect that isn't well understood so far is the role of inland waters (both lakes and streams) in the C cycling. It has been confirmed that inland waters not only process, transport and burry C, but may also act as potential hotspots of greenhouse gas emissions (CO2 and CH4) into the atmosphere.
In my PhD project I focus on quantifying greenhouse gas emissions from inland waters located in one of the least studied but largest terrestrial northern ecosystems in the world – Western Siberia. The area is considered to be a huge C stock of global significance, the fate of which concerns many scientists around the world. As climate warms, there is a growing uncertainty in how this climate-sensitive system will respond to the ongoing warming trends and what consequences it will have for the future.
My research will inform how biogeochemistry, hydrology and permafrost dynamics interact and impact C cycle in permafrost-affected environments.
