A. Scientists Look into How Marine Aerosols May Affect Global Climate

Narrator: This is Science Today. Marine aerosols are particles that are produced by waves crashing in the ocean. One of the major components of these particles is sea salt, but that's not the only substance. A team of researchers led by atmospheric scientist Kim Prather of the University of California , San Diego 's Scripps Institution of Oceanography, are looking into what other particles are present and just how they may affect global climate.

Prather: Since the ocean represents such a large fraction of the Earth over seventy percent of the Earth is covered by the ocean we figured that if we can understand how those aerosols are behaving and affecting climate, potentially regional climate patterns, then we can start to understand the impact of a very, very large source of aerosols to our atmosphere.

Narrator: This research may also help scientists understand how marine aerosols affect human health.

Prather: There has not really been a lot of research done in this area, but it's certainly something that I would say should be looked into at some point.
