Bubbles in the sea surf adsorb and carry viruses to the surface where they are propelled into the air on tiny jets of seawater when the bubble bursts. The ejected jets become tiny drops of aerosol. The buble adsorption and virus concentration in the surf is analagous to industrial bubble levitation processes that concentrate metallic ores, enzymes, and finely divided organic crystals. Bubble levitation of viruses delibrately injected into the surf produced 200 times more virus per milliliter in the aerosol than were present in samples from the surf. Some aerosol drops created by the surf and carried by the wind fall out on the beach. The frequency of virus-bearing drops, that is, the number of plaques on seeded plates exposed on the beach, decreased exponentially with the distance downwind from the surf.
