pH微电极法原位直接测定海水微表层的厚度

借助pH微电极和超微游标移动装置, 首次提出和建立了原位直接测定海水微表层厚度的方法, 这是海水微表层取样和研究上的重大创新. 应用直线相交法, 测定的海水微表层厚度约60 μm; 这不仅与按传统的平板玻璃法和“海水物理-化学突变层”测定的海水厚度为(50±10) μm一致, 也与国际文献报道的结果一致. 文中方法在海洋化学上将有重要的海洋生物地球化学意义.     

Direct determination of thickness of sea surface microlayer using a pH microelectrode at original location

The sea surface microlayer (SML) is the interface layer between seawater and atmosphere, which is a new study field developed from the intersecting and infiltration of ocean science and atmosphere science, including the SML physics, the SML chemistry, the SML biology etc. It in-volves the recip rocity of sea-air, the globe cycle and flux of substances, so it is a key item of the global cooperative research on ocean science[1,2]. It should also be an important research field of SOLAS (sur…
