Ocean zine making in the pub during #OSM26! Please join waterwayscollective.org and the @mastscot.bsky.social Energyscapes Working Group for an evening of #zines and collage in a cosy #Glasgow pub, following day 1 of the 2026 Ocean Sciences Meeting. Sign-up link below, spread the word!

We usually think of photosynthetic bacteria as the main N2 fixers in the world's oceans . Using a mechanistic model we estimate that heterotrophic bacteria are responsible for 10% of the global N2 fixation. And it also occurs temperate waters. www.science.org/doi/10.1126/...

Particle-associated N2 fixation by heterotrophic bacteria in the global ocean

Heterotrophic bacteria fix N2 in more diverse environments than previously thought, critical for the oceanic nitrogen cycle.
