Pollutant Transport in the Coastal Zone (and in AIR!) in Imperial Beach

Researchers at Scripps Institution of Oceanography and the Jacobs School of Engineering have teamed up to study pollutant transport in the coastal zone of the Southern California Bight.  Their laboratory is Imperial Beach, a neighborhood south of San Diego and north of the US-Mexico Border, near the outlet of the Tijuana River.  The Prather Group is sampling air, looking for the fluorescent signature of the (harmless) bright red dye that has been deliberately deposited in the ocean, to mimic a major contaminant plume.  Since the dye is in the coastal surf zone, sea spray aerosol particles produced by the breaking waves can loft some of this material in the atmosphere.  Our group is looking to understand the extent of the "pollutant" transport in the atmosphere by sampling aerosols on the beach, and some locations downwind.
