Sea foam - Wikipedia
These bubbles get transported around the top few meters of the surface ocean due to their buoyancy. The smallest bubbles entrained in the water column dissolve entirely, leading to higher ratios of dissolved gases in the surface ocean. The bubbles that do not dissolve eventually make it back to the surface.

2024年6月16日 — If you shake this glass of ocean water vigorously, small bubbles will form on the surface of the liquid. Sea foam forms in this way - but on a much grander scale - when the ocean is agitated by wind and waves. Each coastal region has differing conditions governing the formation of sea foams.
What is Sea Foam? The Phenomenon of a Foaming Ocean - Ocean …
When we speak of sea or ocean foam, we refer to the accumulation of bubbles and froth that forms on the ocean’s surface. Ocean foam can be found in a variety of shapes, sizes, and colors. For example, depending on its composition, the foam can be colored from white to dark brown.

2023年3月31日 — These little bits of “stuff” in ocean waters are made up of salts, fats, proteins, algae, plankton, bacteria and more. These act as a surfactant, or surface-acting agent, which reduces tension on water molecules, creating bubbles. Another popular foaming substance—soap—is also a surfactant.

2019年6月16日 — As the methane bubble pops out of the seafloor, it represents a super-high concentration of methane close to the seafloor, while the surrounding ocean water has a much lower concentration of methane. “The water and bubble methane concentrations are not in a chemical equilibrium,” explains Jens.
Physics - Why Seawater Is Foamy
2023年9月8日 — In a collision between two bubbles, these forces greatly reduce the rate at which the liquid separating the bubbles can flow away. This understanding, the researchers say, explains why foams arise so easily in salty seawater and could be …

2023年11月30日 — The sea foam bubbles happen because of molecules called surfactants, which Popular Science explains are "sticky molecules that cling to the surface between water and air." This sea surface microlayer can come from natural sources, like algae and seaweed, or from human pollution, like fertilizers, detergents and sewage.

2022年5月3日 — Here, we present bubble measurements from the HiWinGS expedition in the North Atlantic in 2013, collected during several storms with wind speeds of 10–27 m s−1. A suite of instruments was used to measure bubbles from a self-orienting free-floating spar buoy: a specialised bubble camera, acoustical resonators, and an upward-pointing sonar.

2022年5月3日 — Visually, we could observe bubbles breaking the sea surface during both seasons. We investigated the size of these bubbles in-situ with a custom-built ocean bubble camera at 2 m water depth...
How Sea Spray Might Disperse Large Particles - Physics
2023年2月3日 — The bursting bubbles in ocean foam produce a mist of droplets that can contain enhanced concentrations of ocean pollutant particles. In single-bubble lab experiments, researchers have now shown that the inclusion of a particular particle in an airborne droplet depends on some details of the fluid motion that occurs when the droplet forms . The ...
