Title: "Impacts of atmospheric anthropogenic nitrogen on the open ocean"
Duce et al.
The paper is the culmination of a project involving 30 researchers from the UK, the US, Germany, Italy, China, the Netherlands, Switzerland, Canada and Chile.
The study found that increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for around one third of the ocean’s external (non-recycled) nitrogen supply and up to three per cent of the annual new marine biological production.
While the increased biological activity has the beneficial effect of drawing down man-made CO2 from the atmosphere, the researchers found that around two-thirds of this is offset by the increase in harmful N2O emissions.
