Marine spraying refers to the aerosol particles formed directly from the oceans, mostly by ejection into the atmosphere by bubbling bubbles at the air-sea interface.

Composition
The aerosol sea salt (SSA) contains inorganic salts and organic matter from the oceans. It is estimated that the amount of organic material transferred to SSA depends on microbiological activity. Organic matter in marine sprays can contain dissolved organic matter or even microbes itself, such as bacteria and viruses.

Effects
Salt sprays are largely responsible for corrosion of metal objects near the shoreline, as salt accelerates the corrosion process in the presence of oxygen and abundant atmospheric humidity. The indirect salt dissolves in the air, but is suspended as fine particulate, or dissolved in a microscopic water droplet in the air.
Chemical resistance
The salt spray test is an important measure of material endurance, especially if the material will be used outdoors and must perform a mechanical load bearing or other important role. These results are often very attractive to the marine industry, whose products may experience extreme corrosion acceleration and subsequent failures due to the saltwater environment.
