    I'm not into the religious side but oil naturally degrades when brought into the open and especially in the ocean. Oil in sea water is not a natural state so all components start to find a 'natural state' ASAP. Similar - you never find free iron in the environment.

    If Hayward hadn't been such a dip this would have never achieved such a status. I guess we can't fault the prez for not understanding how to proceed as he is a lawyer.
    That's funny because I was considering quoting Carl Sagan, "Absence of evidence is not evidence of absence."

    In fact, even though BP and others with the same ax to grind can't find any of the recently-spilled oil, other investigators are finding it. In the case of any recent, sizable man-made, marine spill, oil is still being found.

    Your free iron analogy is faulty. The fact that iron is required by all or virtually all living organisms, and iron chemistry conspire make that true. The same is not true for petroleum. (Note that iron is not soluble at a pH reasonable for most living things.) Iron is actively soaked-up by living things because they need it. Petroleum is soaked up by living things and it is toxic. Iron is green. Petroleum is not.

    I do believe that natural organisms can break down petroleum in sea water. They can do it because the same characteristics make them adapted to "making a living" by breaking down related, natural chemicals. This does not mean that they can do it fast enough or in a way that significantly mitigates the effects of the spilled petroleum. Anyone that believes that we understand the process of the consumption or sequestering of large amounts of oceanic petroleum has their head in the oil-soaked sand. No one will know the effects of this recent Gulf spill for AT LEAST a couple of years.

      The analogy with the iron is not great as it is affected by less a variety of things in the environment than oil is.

      What you mention about all living things needing iron may well be but it is such a minute amount as to make no difference. But what I was trying to say that Fe is not found in the environment. Fe2O3 & Fe3O4, yes as they are natural.

      İf you place a pile of iron ore (Fe2O3 or Fe3O4) in the ocean and leave it for a thousand years it will still be there in the same quantity. Oil - no it will not.

      I am certain no one understands how and where all the oil goes - and the clowns from the universities least of all. There has been lots of noise from the 'can't do so I will teach' types in the news this week.

      It has been seen in many places that the mess slowly goes away - despite the panic by a small portion of the population. The warmer temperatures in the more shallow areas of the Gulf of Mexico is a better case than in Alaska.

        The Carl Sagan quote is cute but meaningless in day to day life.

        Kind of like saying, 'I wish' or 'I hope'. Two of the most stupid statements man can make.

          You can not reasonably say that pointing out a logical fallacy is meaningless in day to day life. Credit Sagan with pointing it out in a cute way.

          "Absence of evidence is not evidence of absence" is another way of saying that these are not logical:

          A has never been disproven therefore A is true.
          A has never been proven therefore A is false.

              Natural oil seeping into ocean waters has gone on since the beginning of time. Currently it is estimated at a rate of 600,000 metric tonnes per year. The spill in the Gulf as tragic as it appears is a drop on the bucket compared to what seeps naturally into the seas from underneath the ocean waves.

                First, what is the source of the calculation of 600,000 metric tons/year, the oil companies with a vested interest in minimizing the magnitude of the spilled oil, or the previously-discredited academic, no-nothing egg-heads?

                Second, according to my calculations on the back of an envelope, your figure is about equal to what is generally-accepted to have been spilled, minus what BP says they recovered. That is in about 1/3 the time and relatively close to an environmentally-sensitive area that produces most of the sea food that is caught in the Gulf. That marshland is also important for attenuating the energy of tropical storms that affect low-lying populated areas.

                I am concerned. Since we can't predict what it will do, the prudent action is to try to predict the worst-case outcome and plan accordingly. Obviously BP did not do that in their drilling operation or they would have planned a better response and had it ready before the well blew up. Prudent can not describe the poor maintenance and intentional disabling of some of their safety equipment.

                  According to the National Research Council, it's estimated over 600,000 tons per year.

                  Natural processes are responsible for over 60 percent of the petroleum entering North American waters, and over 45 percent of the petroleum entering the marine environment worldwide.

                  Some other articles regarding this subject:

                  In recent decades scientists have made substantial progress in understanding how oil enters the oceans, what happens to it, and how it affects marine organisms and ecosystems. This knowledge has led to regulations, practices, and decisions that have helped us reduce sources of pollution, prevent and respond to spills, clean…

                    How many sources would you like? None are from oil companies.

                      And let's keep it that way in the future since we have already doubled this year's quota. In addition, it is not just how much, but where and how much.

                        Not to worry - in a few years people will look back and wonder what the fuss was about.

                        The professors who are screaming will have changed their story and be saying 'I told you so' as well.

                        Stuff happens - let the law go after BP and maybe they can do some good. Enforce the rules for drilling and forget about the environmentalists ban on the continental shelf.

                        If we make it too tough to drill then Cuba can allow the Chinese to come drill in their waters. Then the GOM gets all the negatives plus-plus and zero benefits. You know good old Fidel would love that - he might even sabotage the rig just to create havoc.

                        Obama could threaten them all he wants and they would tell him to PO.

                          Quote, 'The underwater oil was measured close to BP's blown-out well, which is about 40 miles off the Louisiana coast. The plume started three miles from the well and extended more than 20 miles to the southwest. The oil droplets are odorless and too small to be seen by the human eye. If you swam through the plume, you wouldn't notice it.
                          "The water samples when we were right in the plume look like spring water," study chief author Richard Camilli said. "You certainly didn't see any oil droplets and you certainly didn't smell it."

                          For the article - http://news.yahoo.com/s/ap/20100820/...il_spill_plume

                          Certainly sounds like dangerous stuff to me! The article is less optimistic than the quote but as all is in unknown territory?

                            What the quoted paragraph means to say is that their past detection methods leave a lot to be desired. Note that plenty of things that you can't smell or see will kill you. Carbon dioxide at normal concentration of about 0.04%. At 5% it will make you stupid, fall down and die in that order. You can't see or smell it.

                            He may have been speaking about a particular depth. since It is contradicting other evidence from the same group. I appears that cameras passing through the same plume had oil droplets sticking to their camera lens.

                            I believe that the correct take-home message is that there is a lot of oil at concentrations that are troublesome and may take a long time to disperse and break down.

                              Here is the deal. Oceans and Petroleum have co-existed for billions or years, and will continue to do so for billion of more years long after man turns to dust. More petroleum seeps naturally into the oceans than man can ever spill into it. Mother Nature or whatever you want to call it has a plan and mechanism's worked out to do deal with it perfected over billions of years. All man has to do in our blink of time on earth is learn to adapt to it. Mother Nature will be just fine.

                                Only very partly true. It might be true that every year as much oil bubbles out of the ocean floor as Bungling Petroleum spilled this year. That amount is spread out over many, thousands, maybe millions, of points. At each point, the rate is relatively low and goes on for years, decades or centuries. The marine microflora is adapted to break down the petro at these points. This does not happen instantly and it can not do it at the rate to match the evil spew from BPs well.
