摘要:
氧化亚氮(N2O)是主要的温室气体之一，影响全球气候，对大气化学也有着重要作用。而海洋是大气中N2O的重要排放源，特别是在近岸海区，N2O的释放量尤为显著。本文概述了海洋中N2O的分布特征、产生和消耗的控制机理及海–气N2O交换通量，并展望了海水N2O的新技术方法，如稳定同位素技术和波长扫描–光腔衰荡光谱技术，以期成为今后海洋N2O的研究利器。
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.
