Known as "The Goo" scientists and Coast Guard officials do not have a clue to what this 25 mile slick is:
Nobody knows for sure what the gunk is, but Petty Officer 1st Class Terry Hasenauer says the Coast Guard is sure what it is not.
"It's certainly biological," Hasenauer said. "It's definitely not an oil product of any kind. It has no characteristics of an oil, or a hazardous substance, for that matter.
"It's definitely, by the smell and the makeup of it, it's some sort of naturally occurring organic or otherwise marine organism."
Something else: No one in Barrow or Wainwright can remember seeing anything like this before, Brower said.
