The agency has been investigating reports of tar balls from Port Everglades to Palm Beach along the coast of the Atlantic Ocean, the Coast Guard said in a statement.
In October, the Canadian Coast Guard cleaned up tar balls floating to the ocean's surface from the site of a World War II era shipwreck off the coast of British Columbia, the Canadian Broadcasting Co. reported.
The U.S. Coast Guard has been searching for tar balls that began showing up on south Florida beaches over the weekend, but so far the source of the black muck remains a mystery.
That was a possible source of tar balls that washed onto the shore in the Huntington Beach area of California in March 2024, officials said.
There's been no evidence that the tar balls came from Port Everglades off the shore of Fort Lauderdale, but giant tanker ships routinely sit near the port.
