Global dispersal of macroalgae-derived recalcitrant DOC may substantially contribute to deep-ocean carbon storage
Macroalgae, the dominant primary producers of Earth’s most productive coastal vegetated ecosystems and a vital component driving ocean carbon sequestration, produce ∼5 to 80% of their net primary productivity as dissolved organic carbon (DOC). However, the global extent, fate, and contribution of this macroalgae-derive...
