Abstract
Atmospheric deposition of nitrogen is one of the most important external nutrient sources. We investigated the concentrations of NO3− and NH4+ in airborne particles at both an offshore and an inshore site in the Yellow Sea. At the offshore site, devoid of local sources and located downwind from the highly developed areas of Korea and China, the concentrations of atmospheric particulate NO3− and NH4+ were ∼88 ± 101 nmol m−3 and ∼102 ± 102 nmol m−3, respectively, likely due to the transboundary long-range transport of pollutants. The inshore site showed a concentration ∼2 times higher than the offshore site. Considering not only dry inorganic nitrogen deposition but also wet and organic material deposition, the total atmospheric nitrogen deposition was estimated to contribute roughly 10 % to the new production in the Yellow Sea.
