Cyanobacteria in the Baltic Sea

I have worked with filamentous cyanobacteria in the Baltic Sea since 2010. I use single-cell methods to study nitrogen fixation on species level in mixed populations, combined with biogeochemical models and long-term monitoring data to study trends across recent centuries along with climate change.
