Artie died last month while scuba diving off the coast of Catalina Island. He had a big heart and fought tirelessly against marine debris.
Dozens took part in the annual coastal cleanup to honor Artie. Volunteers flocked to the Deep Blue Scuba and Swim Center in Long Beach for the inaugural Underwater Cleanup.
Artie's sister came out to the event, which took place at Belmont Veterans Memorial Pier.
Organizers say underwater cleanups are merely a temporary fix to a long-term problem.
