What is this mystery object washed ashore in South Carolina? (video)

The Lowcountry Marine Mammal Network asked for help identifying the object

A mystery came out of the ocean on South Carolina’s Seabrook Island, and authorities haven’t yet identified what some are calling “space junk.”
The Lowcountry Marine Mammal Network was the first to notice, posting a photo on Facebook of a “mysterious object that washed ashore” on Thursday. The island is about 24 miles south of Charleston.
The object is big, taller than a woman standing nearby, and it’s cylindrical.
It also looks like it’s made of concrete, but Marine Mammal network officials say that’s deceiving. Touch it and it feels like “a soft foam,” said the network, adding that it was quickly whisked away by town officials.
The Lowcountry Marine Mammal Network asked for help identifying the object and the Kiawah Conservancy shared the plea on its Facebook page. Dozens of people have responded with guesses ranging from parts of an alien craft to refuse from a “government munition dumping site” in the Atlantic.
