Nitric oxide (NO) in the Bohai Sea and the Yellow Sea

Data sets

Nitric oxide (NO) concentration in the Bohai and Yellow Seas during June 2011, with a set up combined with purge-and-trap setup and a fluorometric detection of NO Y. Tian https://doi.org/10.1594/PANGAEA.907361

Short summary

Nitric oxide (NO) seems to be widespread, with different functions in the marine ecosystem, but we know little about it. Concentrations of NO were in a range from below the limit of detection to 616 pmol L⁻¹ at the surface and 482 pmol L⁻¹ at the bottom of the Bohai and Yellow seas. The study region was a source of atmospheric NO. Net NO sea-to-air fluxes were much lower than NO photoproduction rates, implying that the NO produced in the mixed layer was rapidly consumed before entering the air.
