well, one of the things that surprised them about this is these microbes were not in low oxygen water, which is what should be happening, so that mechanism is unclear at the mo...........

That's scary if that surprised them. Ii should have been expected. Microbes are very simple and adaptable. A massive, historically large food source was dropped in their laps and all they had to do was evolve into something able to handle the higher oxygen rates.

shhhhhhhhhhh, be careful using big words like "evolve" and implying "evolution" around right wingers. They dont believe in stuff like that.

Actually, there are bacteria there that have the capability of using most any carbon source imaginable. When a novel carbon source becomes available, the strains that can utilize it have a population explosion untill it is depleted. Problems are twofold. One: Utilization of a carbon source for respiration generally depletes any available oxygen and can create a "dead zone" where higher life cannot exist. Dead organisms pile up and make the problem worse as they decay.
Two: The byproducts of this respiration are frequently more toxic to other life than the original carbon source. In the microbial world, there is constant chemical warfare. Once a cohort of microbes has found food whether it is in a marine, freshwater or terrestrial environment, it is to their advantage to create toxins to eliminate the competition as it were.

(I knew that marine microbiology course in grad school would come in handy one day)

Really? YouTube video?

Thats real scientific Samboct...

Again, your standards are very flexible.

You know- I tend to believe people until proven otherwise. Now you've got two unconnected individuals claiming continuing surface oil issues in the gulf- certainly enough to make me think that something is probably going on. How many claims is it going to take before you admit that perhaps not all is well? And observation is required before constructing a hypothesis. So while these reports may not be scientifically rigorous data points, they're certainly sufficient to do further investigation. You can't do science with your eyes shut- or your mind. Have you considered this conundrum? You don't appear to....

Since the federal agencies such as NOAA have done such a sterling job from the get go on this oil spill, accepting uncritically BPs estimate of 5,000 barrels per day initially, I tend to now look a bit more critically at what they're coming up with now. So unless somebody from one of these agencies wants to address how this oil is showing up on the beach, I'm going to assume that they don't know.

DS-

A massive, historically large food source was dropped in their laps and all they had to do was evolve into something able to handle the higher oxygen rates.

umm, this sounds backwards to me. If you're going to cut up the compounds that make up oil- odds are you're going to be doing some redox (reduction/oxidation) reactions. This means that you're going to break some of the bonds in the molecules that make up the oil- it's really a bit of a soup. Let's say that you've got a carbon-carbon double bond which the microbe attacks (single carbon bonds are less reactive). Well, you're going to need something to put at the end of those two carbons- typically an oxygen to make either an alcohol, an aldehyde, or a carboxylic acid depending on the level of oxidation you can carry out. But all of these reactions require oxygen to drive them and to incorporate. So the question becomes, if the bugs are chewing up the oil- why aren't the oxygen levels in the water dropping? And why aren't the CO2 levels rising? Something doesn't add up... Of course, if the oil really hasn't been changed much, and the bugs haven't started reproducing like bunny rabbits, well, then you'd expect the oxygen levels and the CO2 levels to pretty much remain where they've always been.....

This spill is going to be studied for a very long time, not weeks or months but years and our knowledge is going to evolve as new data becomes avaialble and is analyzed..

Massive Oil Plume Confirmed in Gulf of Mexico
Contrary to expectations, a plume of oil formed in the Gulf of Mexico after the Deepwater Horizon blowout
By David Biello

"But there are significant hydrocarbons, specifically the benzene, toluene, ethylbenzene and various xylenes Sentry was set up to sniff out. The continuous deepwater plume had such hydrocarbon concentrations of 50 micrograms per liter, indicating additions of at least 5,500 kilograms per day from somewhere, most likely the spewing Macondo well. For comparison, that is more than twice as much added by all the natural oil seeps in the northern Gulf of Mexico. And a more diffuse plume existed at shallower depths between 50 and 500 meters. Sentry tracked the plume for 35 kilometers from the source and had not found its end before operations had to be called off because of the approach of Hurricane Alex. "It therefore appears likely that the plume extends considerably beyond the survey bound," the researchers wrote in the paper presenting their findings, published online in Science on August 19. "

(break)

"And it remains unclear if the plume detected by the WHOI scientists was the only plume or if others formed as well. Scientists from the University of South Florida found oil droplets likely to have come from the Deepwater Horizon blowout coating the sediment in DeSoto Canyon to the east-northeast of the Macondo well in August. "There may have been others in other places at other times," Camilli says. "We just don't know.""

Just FYI, it bears note that this data is two months old. The plume being reported was found between June 19 and June 28.

The sad fact is that no one knows what the long-term environmental consequences are going to be. Scientists are going to spend months, if not years, trying to figure it all out, and of course no one at BP knows because no one at BP gives a damn. Maybe things will turn out fine, and maybe they won't. No one can say--not even Sanity and all the other experts on Collarme.

I never claimed to be an expert john, though I believe samboct did and I know Archer did as well. However, I am doing a pretty good job of deflating the far left propaganda claiming that the Gulf of Mexico was totally covered in crude and can never possibly recover.

So you're back to claiming the photo was a fake? Go bother the NASA guys about it. Let me know when they tell you to get stuffed.

Back to it? That photo never proved that the Gulf of Mexico was totally covered in oil as you tried to assert.

The premise of that thread was pure bs the whole while.

Sanity,

What I would like to know is why, in a day and age when corporations will flat out lie to cover their asses off until they're threatened with government sanctions...law suits don't even deter them these days, you think that anybody should believe one word of a study paid for by BP's money?

Now, BP is accountable for the clean up costs. Which, would stand to say, are likely to be extraordinary giving the size of the spill...so would it be even possible (to you, Sanity) that BP would "hire" a set of scientists to state that suddenly the oil is mostly "gone" and "you folks have nothing to worry about"?

I mean, it's not like they lied to us in the first place about how much oil was being spilled.

boi

How can that be? DK is claiming he has proof, hard evidence that the the Gulf of Mexico is now a lake of nothing but crude oil...

quote:

ORIGINAL: yummee

I'm in South Louisiana (between Lake Ponchatrain and Lake Maurpas). The white shrimp season opened the other day here. Only one in over a thousand samples taken from the white shrimp from the Gulf of Mexico has revealed any toxins from oil or dispersants. Of course, the leak was/is horrible. Cleanup is ongoing and should continue, of course. We are struggling now to get BP to do a 5-year marketing campaign reassuring the rest of the country that the seafood is tested ... rigorously. BP, so far, does not feel it is their responsibility to do so. I realize everyone has an opinion, and certainly has a right to share it. The biggest struggle here at the moment is hit after hit after hit to the Louisiana economy. We still have not recovered from Katrina, 5 years ago. We are battling to hold onto one of our major industries (oil) in a SAFE manner. It looks like we will now lose the majority of another of our major industries (seafood). We have enough trouble competing with Chinese seafood, which Americans seem to not have a problem buying and trusting the safety of. We all know how safe Chinese products have proven to be.

The seafood coming out of the Gulf of Mexico is tested. We are eating it, not tasting oil or chemicals, not getting sick.

If you want to help during this crisis, spend your tourist dollars along the Gulf Coast. I was in Gulf Shores the other weekend. I saw no oil, tar, dead animals, etc. If you want to help during this crisis, buy Gulf seafood and enjoy it. It's good and safe.

It was mostly mud in that photo, wasnt it. Just as I wrote in the initial thread...

Instead of violating TOS with these typical cheap personal shots of yours luce, why not try to discuss the facts and argue the merits of whats being posted by those of us who are actually trying to contribute something to the thread.

Do that and you might possibly stick around to post another day...
