The abundance of organic compounds at the surface of oceans provides a link between ocean biogeochemistry and the atmospheric chemistry of the marine boundary layer through physicochemical processes at and near the air-water interface. These processes, in turn, affect the formation and growth of marine boundary layer aerosols, being involved in primary and secondary aerosol formation and evolution in the atmosphere. The photochemistry and photosensitizing properties of the kinds of biogenically derived organic coatings present at the ocean surface have until now only been suggested but never fully addressed. We present the current state of understanding, and make some suggestions for where the field may go, for greater understanding of the possible feedbacks of air/sea exchanges on air quality and climate change.
海洋表面有机化合物的丰度通过气-水界面及其附近的物理化学过程,将海洋生物地球化学与海洋边界层的大气化学联系起来。这些过程反过来又影响海洋边界层气溶胶的形成和生长,参与大气中一次和二次气溶胶的形成和演化。目前只是提出了海洋表面存在的生物衍生有机涂层的光化学和光敏特性,但从未得到充分解决。我们介绍了目前的认识状况,并就该领域如何进一步了解空气/海洋交换对空气质量和气候变化的可能反馈提出了一些建议。
