Introducing the NUM model version 1.0 (github.com/Kenhasteande...): a validated plankton community model designed for global plankton ecology on a laptop. No more phyto/zooplankton but a modern description of mixotrophs and multicellular plankton.

Computational library for the nutrient-unicellular-multicellular plankton modeling framework v. 1.0
Abstract. The nutrient-unicellular-multicellular (NUM) model is a trait-based model of unicellular and multicellular plankton that uses body size as the main structuring variable for community composi...

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.

Squid die when they reproduce. We estimate that sinking squid carcasses locks away 11-12 Mt carbon/year in the deep oceans. Increasing squid fisheries interrupts this sequestration and sends it to our dinner plates - where it is respired to the atmosphere. www.sciencedirect.com/science/arti...
