Scientists from Scripps Institution of Oceanography at UC San Diego will be conducting field experiments from Sept. 8 to Oct. 31 to study pollution transport along the Imperial Beach shoreline during dry weather when the Tijuana River flow is small and beach usage is large.
Pollution transport and dilution will be simulated by releasing EPA-approved, non-toxic, pink dye at selected shoreline locations.
The dye, carried along in the prevailing alongshore currents in the surf zone, will form a plume similar to that formed by wind blowing past a smokestack. Wave, current, depth, dye and biological measurements will be used to track the dye plume.
The Imperial Beach Pollutant Transport and Dilution Experiment (IB09) will span between the Tijuana River mouth and the southern boundary of the Silver Strand State Beach, a region selected for its long, straight coastline with a history of water quality problems when it rains.
During the experiment, the public can expect to see an array of fixed-in-place, cross-shore instruments mounted on tripod frames to be located offshore of Imperial Beach Boulevard, flags, fiberglass poles, surf zone drifters and pink dye in the water. All-terrain vehicles will be used to survey the beach and specially equipped Jet skis will collect data offshore. Warning signs will be posted.
The project is funded by the National Science Foundation, the Office of Naval Research, California Sea Grant and the California Department of Boating and Waterways.

Scripps Institution of Oceanography at the University of California San Diego, is one of the oldest, largest, and most important centers for global science research and education in the world. Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical, and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today on every continent and in every ocean. The institution has a staff of more than 1,400 and annual expenditures of approximately $195 million from federal, state, and private sources. Scripps operates oceanographic research vessels recognized worldwide for their outstanding capabilities. Equipped with innovative instruments for ocean exploration, these ships constitute mobile laboratories and observatories that serve students and researchers from institutions throughout the world. Birch Aquarium at Scripps serves as the interpretive center of the institution and showcases Scripps research and a diverse array of marine life through exhibits and programming for more than 430,000 visitors each year.
