RESEARCH: Atmospheric deposition of nitrogen

Atmospheric deposition of nitrogen increases with increasing combustion of fossil fuels. The nitrogen in atmospheric deposition has increasingly been recognized as important source of nitrogen fueling phytoplankton in regions of the ocean downstream from regions of high rates of fossil fuel consumption. Additionally, atmospheric deposition has geochemical signatures, including N:P ratios > 16:1 and δ¹⁵N values similar to those associated with N₂ fixation.
