Equatorial upwelling of phosphorus drives Atlantic N2 fixation and Sargassum blooms - Nature Geoscience
High near-surface nitrogen-fixation rates that promoted the recent growth of the Great Atlantic Sargassum Belt were tied to greater upwelling of phosphorus from the equatorial Atlantic, according to c...

The driver of Sargassum blooms in the Atlantic Ocean:
Upwelling of phosphorus-rich deep water promotes an N-fixing symbiont of the Sargassum algae giving it a competitive advantage.
