Drivers of the global phosphorus cycle over geological time
Phosphorus is a key limiting nutrient of terrestrial and marine primary production. Thus, the global phosphorus cycle is intimately linked with the…

The history of Earth’s sulfur cycle
Sulfur is a critical component of Earth’s surface evolution owing to its dynamic roles as a redox buffer and nutrient as well as forming the bas…
Biogeochemical consequences of marine fisheries and aquaculture
Marine fisheries and aquaculture are important contributors to global food security but disturb biogeochemical cycles from local to global scales. …
Seasonal productivity of the equatorial Atlantic shaped by distinct wind-driven processes
The eastern equatorial Atlantic hosts a productive marine ecosystem that depends on upward supply of nitrate, the primary limiting nutrient in this…
Decadal persistence of grassland soil organic matter derived from litter and pyrogenic inputs
The stabilization of carbon (C) and nitrogen (N) from organic inputs in soil organic matter constitutes a critical process in ecosystem biogeochemi…
Contribution of sandy beaches to the global marine silicon cycle
Dissolved silicon levels in the ocean, which can shape marine carbon cycling owing to silicon’s role as a nutrient, are largely controlled by inf…
