Ocean spray aerosol formed by bubble bursting are at the core of a broad range of atmospheric processes: they are efficient cloud condensation nuclei and carry a variety of chemical, biological, and biomass material from the surface of the ocean to the atmosphere. The origin and composition of these aerosols is sensibly controlled by the detailed fluid mechanics of bubble bursting. This perspective summarizes our present-day knowledge on how bursting bubbles at the surface of a liquid pool contribute to its fragmentation, namely to the formation of droplets stripped from the pool, and associated mechanisms. In particular, we describe bounds and yields for each distinct mechanism, and the way they are sensitive to the bubble production and environmental conditions. We also underline the consequences of each mechanism on some of the many air-sea interactions phenomena identified to date. Attention is specifically payed at delimiting the known from the unknown and the certitudes from the speculations.
它们是高效的云凝结核，将各种化学、生物和生物质材料从海洋表面输送到大气中。这些气溶胶的起源和组成受到气泡破裂详细流体力学的显著控制。这一观点总结了我们目前关于液池表面的破裂气泡如何导致其破碎，即形成从液池中剥离的液滴以及相关机制的认识。特别是，我们描述了每种不同机制的界限和产量，以及它们对气泡产生和环境条件的敏感程度。我们还强调了每种机制对迄今为止所确定的众多海气相互作用现象中的一些现象的影响。特别关注区分已知与未知、确定与推测。
