Location of Spilled Oil From 2010 Deepwater Horizon Event Found 73

Chipmunk100 writes: A study published in the journal Proceedings of the National Academy of Sciences (abstract) claims to have identified the location of two million barrels of submerged oil thought to be trapped in the deep ocean following the 2010 Deepwater Horizon spill. By analyzing data from more than 3,000 samples collected at 534 locations over 12 expeditions, they identified a 1,250-square-mile patch of the deep sea floor upon which 2 to 16 percent of the discharged oil was deposited. The fallout of oil to the sea floor created thin deposits most intensive to the southwest of the Macondo well. The oil was most concentrated within the top half inch of the sea floor and was patchy even at the scale of a few feet."

    According to leading chiropractors, oil is not only not harmful to marine environments, but is in fact highly beneficial! In fact, we should be dumping millions of barrels every year into the Gulf of Mexico, and should pay back all the money BP has to pay out back to them at one trillion percent interest!

        This is also confirmed by homoeopaths

        This reminds me, apropos of nothing and completely offtopic (sort of): I walk the dog early in the morning, before 6am while listening to the news on my portable radio. Due to some strange meteorological phenomenon, I am able to pick up a 500watt station out of an exurb that's 20 miles away, and carries Alex Jones' show (the station calls itself, "Freedom Radio").

        So anyway, as you can imagine, the big story the past week has been Ebola and how it's no coincidence that Ebola is from Africa and the President is from Africa. That Ebola is being used to take away our freedoms (but not "Freedom Radio" for some reason).

        The "expert" that Alex Jones has on every single morning is a naturopath from Arizona who has developed an "anti-viral" tonic made from colloidal silver and antioxidants ("equivalent to 10,000 blueberries!"). Of course, the 800 number is given throughout the show where for a limited time, with every order you get the doctor's book about the things "The Medical Industry Doesn't Want You To Know". Then they take calls from listeners, and just thinking about the voices of the people who call in makes the little hairs on my arm stand up. I mean, these people are skeered to death that weaponized Dominican kids are being shot up with Ebola by ISIS and sent to their little Utah town by the Democrat/Catholic cabal (I'm not making that up). One lady who said she was getting chemotherapy for cancer was crying on the phone she was so terrified that the Ebola was going to come to her home near Lake of the Ozarks and kill her because the chemo has lowered her immune system. Just sobbing. Saying that hearing Alex Jones and going to Infowars is the only thing keeping her going because she knows it's God's Truth. And Alex Jones and this witch doctor are telling her that if she orders some of this colloidal silver tonic with antioxidants it's going to build up her immune system, bless her heart. And I don't know if any of you have heard Alex Jones lately, but he now sounds exactly like Sam Kinison. The same accent, the same timbre, the exact same dynamic range from hoarse whisper to hoarse scream.

        Alex Jones likes to say, after he's gotten people completely apoplectic with fear, that we shouldn't worry, because he's read the book (bible) and he knows how the story ends (victory for the righteous and all patriots), So nobody should worry. This exact sequence, with small variation, goes on every single morning. I hear that stuff and really feel sad. My wife tells me I shouldn't listen, even though it's not really having an effect on me besides making me sad (except for the hole I've started digging in the back yard). Ok, that last part is a joke, but really, the whole thing is about as unfunny as it gets.

        I'm sorry that I threw all that in here as a reply to a mild joke, but hearing "homeopaths" and "cancer" made me think of it, and when I'm half in the bag I start making random associations from a need to unburden my sorrow at the state of humanity OK, I think the second period of the Blackhawks game is starting, so I've gotta go.

          I think someone should make a list of the advertisers for radio shows that purport to be about news. I'm sure there is some sort of correlation between the quality of products advertised and the average intelligence (or maybe education) of the listener.

      You joke, but the equivalent of a few million barrels of oil enters the gulf of Mexico every year through naturally-occuring seeps [wikipedia.org].

      • Yup, just like adding up all the blood Americans lose to papercuts ever year. Assume 1 drop of blood is lost per papercut, or .06 ml. A highly conservative guess is 1/1000 americans get papercuts in a year. (300,000,000/1000)*.06=18 liters of blood. So obviously it wouldn't hurt you if you suddenly lost 18 liters of blood, since that amount is lost in minor little papercuts every year.

        Scale matters, and concentrating a huge amount of oil, (or in the above example blood loss) makes a big difference.

        • Aside from the fact that you're comparing the supposed collective seeping of a liquid into the ocean with human bloodloss and a bunch of random numbers you pulled out of your bum, I'm sure the fishers that are out of business due to the incredible damage to the marine food web are very thrilled that you think oil contamination is harmless, let alone the effects of Corexit, the extremely toxic that BP wantonly sprayed all over the spill to help hide evidence of the crime.

              You're comparing the hypothetical seepage of oil--which would in the ocean--to the loss of blood, which is rejuvenated. But I bet you guys felt really clever about the first troll account's unfunny set-up into your right-out-of-your-ass non-factoid. Cry more, BP trolls.

            That's a bit of exaggeration. They found (back in 2010) layers in the water column that had tiny suspended particles/droplets of oil. It's not like it was a 100m-thick layer of mostly oil. It was traces. And it's unlikely there's any sign of that suspended oil left in the water column by now, years later. It's either been biologically degraded completely (a process already in progress at the time of that article) or settled onto the sea floor as a thin layer mixed with sediment.

            I think you just experienced backlash that stems from BP trying to use natural seeps to downplay the magnitude of the Deepwater Horizon event. Living on the gulf coast I experienced first hand their spin doctors at work telling us about natural seeps and microbes that eat crude oil.

            From the large tar balls washing up on our beaches, the residue that stayed in our marshes, the deaths of marine animals and the increased erosion from the death of grasses and trees along the waterline, only a fool would have fell for their bullshit.

            I know that you only meant to bring up a natural phenomena but bringing up the topic of natural seeps in a story about the Deepwater Horizon does make you look like a shill for BP.

    This will now get covered with silt and eventually become an oil reservoir for future generations a million years down the line. Bravo to BP for thinking so far ahead!

    • by Rei ( 128717 )

      I question how much it's still "oil". Oil, outside of reservoirs, evolves. The volatiles slowly separate out; their ultimate fate is evaporation and photodegradation. The shortest chains are lost rapidly, but the longer they get, the longer they take to disappear. As volatiles are lost, the oil thickens. It eventually becomes tar, and then basically asphalt.

    Hasn't anyone yet realized that oil is lighter than water and would not, therefore, sink to the bottom? I don't know what these geniuses really found.

      Evaporation and emulsification; evaporation leaves behind the heavier components of oil, emulsification creates a seawater-oil mixture that will sink.

      There's also all the dispersants that BP flung at the leak, whose long-term effects probably still aren't fully understood.

        This is interesting, as there has been a huge fight in Canada about whether heavy oil sinks or floats (the answer seems to be: sinks, at least after some processing by sun/wind/flotsam/etc) but it has been presented to the public as if there was something special about that.

        Whereas these results seem to indicate that a very substantial fraction of ordinary light crude sinks, so there is no particular additional danger posed by bitumen.

    • The dispersant Corexit was used to disperse the oil.. straight to the ocean floor.. The EPA told BP to stop using Corexit, which is carcinogenic and neurotoxic, and BP simply ignored that order--making potentially hundreds of thousands sick nearby. Oil is bad to touch, and Corexit is bad to touch, but the combination is a death-sludge. BP is a truly evil entity, in so many ways.
  • As someone who was out there in the gulf documenting the effects of the spill, I'm disappointed that there is no actual details or data or maps indicating where actually the oil is located? Where are the details?

So almost 5 million barrels were spilled in 2010, and the largest oil tanker can carry 2 million barrels.
