Tiny photosynthetic organisms help transport carbon to the depths of the Baltic Sea

Researchers at Stockholm University have found that specific picocyanobacteria in the Baltic Sea form aggregates that help transport carbon to the ocean floor. This process is vital for understanding how marine ecosystems regulate atmospheric CO2 levels.
Why it matters
As climate change alters ocean conditions, understanding the biological carbon pump is essential for predicting future atmospheric carbon concentrations.
