[1]海洋中溶解惰性气体的测量产生了关于水团形成过程的重要信息。我们目前氩，氮，氖数据从副热带和副极地北太平洋和副热带北大西洋。所有三种气体在表面都过饱和。在深海，Ar和N-2是不饱和的，而Ne保持过饱和。所有的数据都落在由准稳态混合层模型预测的范围内，该模型只允许温度变化，以及扩散和气泡介导的气体交换。这一结果表明，这三个过程是对全球海洋惰性气体饱和度分布的一级控制。
[1] Dissolved inert gas measurements in the ocean yield important information about processes that occur during water mass formation. We present argon, nitrogen, and neon data from the subtropical and subpolar North Pacific and the subtropical North Atlantic. All three gases were supersaturated at the surface. In the deep ocean, Ar and N-2 were undersaturated while Ne remained supersaturated. All the data fell within the range predicted by a quasi-steady-state mixed-layer model that allows only temperature change, and diffusive and bubble-mediated gas exchange. This result suggests that these three processes are the first order controls on the global oceanic distribution of inert gas saturations.
