海洋气溶胶已从南大洋边界层取样。通过X射线光谱法，已研究了单个颗粒的元素组成。这些数据揭示了在南大洋上发生的两个化学过程：（1）海盐被酸性物质改变，其中Cl−被SO 42 −和/或NO3−取代;（2）蒸发的海水滴中的部分重结晶，随后破碎。当有来自自由对流层的质量转移时，这些现象的影响似乎同时增强。
Marine aerosols have been sampled from the boundary layer over the Southern Ocean. By means of X-ray spectrometry, elemental compositions of individual particles have been studied. The data reveal the occurrence of two chemical processes over the Southern Ocean: (1) modification of sea salts by acidic materials, where Cl−is replaced by SO42−and/or NO3−and (2) fractional recrystallization within evaporating seawater drops followed by shattering. The effects of these phenomena appear to be simultaneously enhanced when there is mass transfer from the free troposphere.
