38th Annual Avalon Harbor Underwater Cleanup

USC’s Catalina Hyperbaric Chamber and Wrigley Institute for Environmental Studies–Catalina Conservation Divers are proud to host Catalina Island’s 38th Avalon Harbor Underwater Cleanup, one of the largest annual dive events in Southern California. The event began in the 1970s in an effort to cleanup Avalon Harbor, and this event is the only time diving is permitted in the Harbor.

Southern California divers have made the Avalon Harbor 
Underwater Cleanup one of their premier social events of the
 year. Divers retrieve trash and lost items from Avalon Harbor,
 and revel in the warm friendly atmosphere of Catalina Island.
 Last year, approximately 498 participants recovered 2,320
 pounds of trash. Proceeds from the event will benefit USC’s
 Catalina Hyperbaric Chamber and Wrigley Institute Scientific Diving Program
