Catch the spindrift

Aerosols of sea spray thrown into the air lead to the seeding of clouds over approximately 75% of the earth's surface. They are generated by "film" or "jet" droplets but the chemical distinction between the two could help us create a better model of climate change. Researchers from the University of California San Diego and elsewhere have identified the differences in the chemical make-up of sea spray particles ejected from the ocean by breaking waves. “It’s the first time anyone has shown that drops from seawater have different composition due to the production mechanism,” said Prather. “We are uncovering how ocean biology influences the physical production processes creating sea spray aerosol," explains Kimberly Prather.
