The coupling of Phanerozoic continental weathering and marine phosphorus cycle
"Organic matter production and decomposition primarily modulate the atmospheric O2 and CO2 levels. The long term marine primary productivity is controlled by the terrestrial input of phosphorus (P), while the marine P cycle would also affect organic matter production. In the past 540 million years, the evolution of terrestrial system, e.g. colonization of continents by vascular land plants in late Paleozoic, would certainly affect terrestrial P input into the ocean, which in turn might have impacted the marine primary productivity and organic carbon burial.
