Possible oil below the ocean's surface, WEAR, September 22, 2010:
As we all know, oil is still in the gulf... sitting on the sea floor and dispersed in the water column...
Dan Thomas, WEAR reporter: We're out here in the Gulf of Mexico about 4 miles off Pensacola beach...
Mike Harrell, Harrell Marine Services: "I have seen what I think and analysis will prove that what I thought was oil."
Dan Thomas, WEAR reporter: I found what appeared to be tarballs, similar to what we've seen on shore. This is video shot by Harrell of a nearby location shows a much thicker brown film. It's not what he was hoping to find... His marine services company depends on the gulf being pristine.
Mike Harrell, Harrell Marine Services: "I've been diving these waters for 25 years and what I have seen, it just doesn't look like it used to."
One group of researchers have observed oiled sediments on the seafloor stretching from the wellhead to 20 nautical miles off the coast of Gulfport, MS.
Today the media is reporting that federal teams have been finding oil just off the coast all along the Gulf.
Now WEAR discovers what appears to be submerged oil four miles from shore.
