Research Topic

Microbial Oceanography of Polar Seas

Research Interest

Polar seas are more affected by climate change and take up more fossil fuel-derived carbon dioxide than lower latitude oceanic regions. Consequently, marine biogeochemical cycles in the water column of polar seas, governed by the delicate interplay between the physical structure of the water column and the microbial plankton community, might be subjected to substantial alterations in the future. We are studying the link between the large-scale water mass transport and microbial community composition and activity in the Arctic Sea and the Southern Ocean.
