In most areas of the (sub)tropical surface ocean, the concentrations of dissolved organic nitrogen (DON) are 1‐3 orders of magnitude higher than nitrate and ammonium. However, the role of of DON in the upper ocean nutrient cycling is not well understood. In a new study, Prof. Xingchen (Tony) Wang and an international team uses nitrogen isotopes to study the cycling of dissolved organic nitrogen in the South China Sea. They found evidence for both production and consumption of DON in the shallow waters of the SCS, indicating that DON is actively participating in the biological N cycle. This article, entitled "Dissolved organic nitrogen cycling in the South China Sea from an isotopic perspective”, was published in AGU’s Global Biogeochemical Cycles.
