Climate relevant gases
We study the formation and transformation/consumption of climate-relevant gases (CH4, DMS, etc.) in sea-ice, water column and sediments.
In-situ and ex-situ measurements of concentrations as well as the isotopic composition of trace gases in sea ice, sea water, pore waters and groundwater are used to understand the underlying biogeochemical processes.
We estimate fluxes at the sea-ice-water interface, through the water column and exchanges at the sediment-water interface. Through this approach, we calculate budgets and determine the sources and sinks of gases in biogeochemical cycles.
