  •  One thing as a Floridian I can be proud of (20+ / 0-)

    is my local paper, The St. Pete Times (no, I don't work for them). They aren't corporate owned. Rather, the paper was put in a trust by the very forward-thinking Nelson Poynter. That has a lot to do with their ability to keep pace with changes in print media.

    Their latest on the BP Catastrophe on the front page today:

    This first story reveals clean-up efforts will have to extend beyond the surface.

    At Pensacola Beach, a USF Scientist finds oil under sand:
    Ping Wang, 43, who has studied beaches for 20 years, dug a narrow trench perpendicular to the shoreline, about a foot deep and 5 feet long. A dark, contiguous vein of oil ran horizontally along the walls of the trench, about 6 inches beneath the surface of the sand.

    Meanwhile, on the dispersant front:

    ...federal scientists confirmed this week what University of South Florida researchers and others had found: plumes of tiny oil droplets that stretch for miles underwater, which "is consistent with chemically dispersed oil." Some of it, they found, had oozed into shallower waters close to shore.

    The link to this story is here.

    •  Scientists confirm UF plumes: Where is media? (10+ / 0-)

      No one is reporting this in national media that I've heard.

      That report of oil within the sand, below the surface. That is scary. I live in N. Cent. FL. and so hate to read that. A very bad sign for sea life.

      Thanks for that information.

      •  That Prof. Blum who was on with Rachel (9+ / 0-)

        said the dispersant made the oil soak in to soils and sand. If that's the case, you beach folks should scream bloody murder.

        Use dispersant to keep it off the beach but make it 10 times worse when it does hit the beach.

        There need to be Congressional hearings just on the damned dispersant and why the government allowed them to continue to use it.

        It rubs the loofah on its skin or else it gets the falafel again.

        •  Exactly right! Well said, Fishgrease. (7+ / 0-)

          Embedded oil/dispersant.

          What exactly are the repercussions of inches of oily sand? Doesn't it also indicate that the seabed must be similarly oiled/dispersant-infected?

          Makes me sick. Agree about hearings on dispersant!

          •  Dispersant said by NOAA to be parts per million (4+ / 0-)

            and therefore I guess, not worriesome in the least.

            In this country, they always present parts per million as nothing. Relying on "common sense" rather than scientific fact.

            Will the hurricane pull up the oil that is below the surface of the Gulf?

            • All of the sampling to date shows that except near
            the leaking well, the subsurface dispersed oil is in
            parts per million levels or less. The hurricane will
            mix the waters of the Gulf and disperse the oil
            even further.

          If the dispersant/oil froth makes globs layer in the fashion described, following tidal action it should ease removal, depending on if/how further tidal action affects the layer that's deposited now.

          A two-inch thick deposit, as the article describes it, at a depth of 6" is not a daunting task to clean up.  And it's fairly innocuous in place.

          Oil in the marshes that's adhering to vegetation and constantly being agitated with no opportunity to settle and deposit like on a beach, is a real headache when it comes to clean up and remediation.  It also represents a far more lethal scenario to marine life than oil on comparatively sterile sandy beaches.

          This appears to be undispersed oil.

          High tide deposited oil on beach in a nice layer.  Next high tide deposited 6" of sand on top.

          Pennsacola Beach appears to be in Escambria, FL, on the barrier islands outside the line of boom which protects the bay.   Pennsacola beach is the boom, as far as nature is concerned.  Aerial photos show no booming of any kind, but they are pretty old 2010-05-15.

          Interaction of dispersed oil with beach sand could get interesting.  But it has been studied and the outcome was at least 49 times better for dispersed oil:

          At the experiment’s conclusion, approximately 49% of the applied oil for the oiled treatment remained in the tanks sorbed to sediments or other surfaces. The rest of the oil was removed via the effluent. In the chemically-dispersed oil treatment, all of the oil was flushed from the tanks; no oil (much less-than1%) remained on the sediments. These studies indicate that a timely dispersant application to spilled oil can reduce residual oil accumulation on beach substrates.

          You could argue that beach protected by booming would be protected if the oil was undispersed but are you really going to stop >>99% of the oil under a wide range of real world conditions including storms?
