海面可以通过多种机制产生气泡，但主要来源是破碎波浪中夹带的空气。气泡将从周围的水中清除物质，从而促进溶解的有机物质和颗粒有机物质的循环。当它们在海面破裂时，这些气泡会产生海盐气溶胶，被从海面微层及其以下清除的物质污染。当气泡浸没时，气泡与周围的水之间会发生气体交换。此外，破碎的波浪和浮出水面的气泡羽流会破坏表面微层，这可能会增强气体直接通过海面的传输。
Bubbles can be generated at the sea surface by many mechanisms, but the main source is by the entrainment of air in breaking waves. Bubbles will scavenge material from the surrounding water, thus contributing to the cycling of dissolved and particulate organic material. When they burst at the sea surface these bubbles generate a sea salt aerosol contaminated with material scavenged from the sea-surface microlayer and below. Gases will be exchanged between a bubble and the surrounding water while it is submerged. In addition, the breaking waves and surfacing bubble plumes disrupt the surface microlayer, and this may enhance transfer of gases directly through the sea surface.
