Nitrous oxide (N2O) is an important greenhouse gas, playing a significant role in the global climate system. The world ocean is believed to be a net natural source of atmospheric N2O, among which the coastal ocean is responsible for a large part of the oceanic N2O emissions. In this paper, the present research progresses of the marine N2O dissolution, fluxes and behavior are reviewed, and in addition, new methods determining the dissolved N2O are introduced, including stable isotopes application and wavelength-scanned cavity ring-down spectrophotometer, so as to provide novel techniques for researching of ocean N2O cycle in the future.
