Volatile organic compounds (VOCs) play a vital role in the global carbon budget and in the regional formation of ozone in the troposphere, and are emitted from both natural and anthropogenic activities. They can also serve as a source of secondary organic aerosol (SOA). Field and model studies showed evidences of a strong marine biogenic influence on marine aerosols. Although knowledge of terrestrial VOC emissions and SOA formation mechanisms has been advanced considerably over the last decades, processes constraining marine VOC emissions and marine SOA formation remain poorly understood. Seawater contains an extremely complex, diverse, and largely unidentified mixture of VOCs. Despite the fact that the ocean covers 70% of the earth’s surface, the role of the ocean in the global budget of VOCs is still unclear. The distribution and emission of sea surface VOCs exhibit considerable spatial-temporal variation, with higher concentrations often, but not always, correlated with biological activities. VOCs in surface seawater have been measured in various geographic regions, however, knowledge of the distribution of marine VOCs and the role of the oceans in the global atmospheric chemistry is still insufficient due to the paucity of measurements. This study reviews marine VOCs in terms of current analytical methods, global marine VOCs measurements, their effects on SOA, and future needs for understanding the role of marine VOCs in the chemistry of the atmosphere.

挥发性有机化合物（VOC）在全球碳预算和对流层臭氧的区域形成中起着至关重要的作用，并且是自然活动和人为活动排放的。它们还可以用作二次有机气溶胶（SOA）的来源。现场和模型研究表明，海洋生物气溶胶对海洋气溶胶具有很强的影响力。尽管在过去几十年中已经大大提高了对地面VOC排放和SOA形成机制的了解，但对限制海洋VOC排放和海洋SOA形成的过程的了解仍然很少。海水中含有非常复杂，多样且基本上无法识别的挥发性有机化合物。尽管海洋覆盖了地球表面的70％，但海洋在挥发性有机化合物全球预算中的作用仍不清楚。海面VOC的分布和排放表现出相当大的时空变化，较高的浓度通常但并非总是与生物活动有关。已在各个地理区域对地表海水中的VOC进行了测量，但是由于测量的匮乏，对海洋VOC的分布以及海洋在全球大气化学中的作用的了解仍然不足。这项研究从当前的分析方法，全球海洋VOC的测量，其对SOA的影响以及对理解海洋VOC在大气化学中的作用的未来需求等方面对海洋VOC进行了综述。已在各个地理区域对地表海水中的VOC进行了测量，但是由于测量的匮乏，对海洋VOC的分布以及海洋在全球大气化学中的作用的了解仍然不足。这项研究从当前的分析方法，全球海洋VOC的测量，其对SOA的影响以及对理解海洋VOC在大气化学中的作用的未来需求等方面对海洋VOC进行了综述。已在各个地理区域对地表海水中的VOC进行了测量，但是由于测量的匮乏，对海洋VOC的分布以及海洋在全球大气化学中的作用的了解仍然不足。这项研究从当前的分析方法，全球海洋VOC的测量，其对SOA的影响以及对理解海洋VOC在大气化学中的作用的未来需求等方面对海洋VOC进行了综述。
