See the article about us in the Union Tribune, "Huge waves at the Tijuana Sloughs are tempting, but dangerous Surfing" (2007-01-02) by Brad Melekian.

This display shows the results of a lagrangrian particle tracking algorithm applied to hourly surface currents. The plot indicates the tracking of water from the mouth of the Tijuana River within the domain observed by SCCOOS. On an hourly basis, 100 particles are released at the rivermouth and tracked for a 3 day period to provide a better estimate of where the Tijuana River plume may be impacting the coast. New positions within the region are updated hourly and the color of the particle represents the age of the particle since it was released. Example animations are available from CORDC Documents.

These graphical displays are intended to be experimental. While considerable effort has gone into ensuring the highest quality data, significant differences between measured currents and actual currents can occur. This information should not be used to make any navigational or other decisions that might endanger public safety or put anyone at significant risk.
