Climate change implications
Dive into the groundbreaking discovery of nitrogen-fixing microbes thriving beneath Arctic sea ice, a phenomenon once thought impossible. These non-cyanobacterial diazotrophs (NCDs) could boost marine ecosystems, enhance algae growth, and even help absorb more CO2 amid rapid ice melt.
In this video, we explore how scientists from the University of Copenhagen found these resilient bacteria in the Central Arctic Ocean and Eurasian Arctic. Previously believed exclusive to warm waters, these microbes possess the genetic tools for nitrogen fixation, potentially fueling richer food webs from plankton to fish.
As Arctic ice fringes host higher activity, climate change may amplify their role, altering global models. Learn why incorporating Arctic nitrogen fixers is crucial for accurate predictions on ocean health and atmospheric CO2 levels.
