The magnitude and impacts of anthropogenic atmospheric nitrogen inputs to the ocean/Величина и влияние антропогенного поступления атмосферного азота в океан

Издание на английском языке
This report provides a new estimate of how much of the fixed nitrogen emitted to the atmosphere from fossil fuel burning and agriculture reaches the ocean in atmospheric deposition - rain and dustfall. The report compares these fixed nitrogen inputs to those from rivers and natural biological nitrogen fixation.
