IMPERIAL BEACH: Surfers and other beach users are invited to a meeting Wednesday to hear about an experiment that will study how pollutants are moved by waves, currents and tides.
The study by scientists from the Scripps Institution of Oceanography will run from Sept. 8 through Oct. 3.
The goal of the Imperial Beach Pollutant Transport and Dilution Experiment is to understand how pollutants such as bacteria get transported and diluted in the surf zone. The information could be used to manage beach closures in California.
The focus of IB09, as the study also is known, will be on dry-weather conditions when the Tijuana River flow is small and beach use is heavy. Scientists will place dye in the water and note how it gets discharged.
The experiment site is from the Tijuana River to just north of the Imperial Beach city limits. The site was selected for its long, straight coastline and history of water-quality problems.
The meeting will be held from 6 to 7:30 p.m. at the Dempsey Holder Safety Center, 950 Ocean Lane.
