Numerous plastic-wrapped bales of marijuana – weighing a total of 1,300 pounds – were spotted floating in the ocean off the coast of Southern California, investigators said.

The Coast Guard recovered 43 bales of what were believed to be narcotics near Santa Catalina Island after a concerned citizen alerted the agency, a news release said.

U.S. Customs and Border Protection (CBP) confirmed the bales contained an estimated $1 million worth of marijuana.
