Natural forcing of the North Atlantic nitrogen cycle in the Anthropocene [Earth, Atmospheric, and Planetary Sciences]

Human alteration of the global nitrogen cycle intensified over the 1900s. Model simulations suggest that large swaths of the open ocean, including the North Atlantic and the western Pacific, have already been affected by anthropogenic nitrogen through atmospheric transport and deposition. Here we report an ∼130-year-long record of the 15N/14N...
