Worry Underwater: Oxygen Levels Drop as Oil Continues to Flow
Marine Animals Crowd Shallow Gulf Waters as Worries Over Oxygen Levels Grow


By MATT GUTMAN and SADIE BASS
June 23, 2010

Evidence of marine biologists' doomsday scenario thrashes in the Gulf waters as sharks crowd into shallow waters.

Undersea accident forces BP to remove cap as oil washes up on Pensacola beaches.

Marine biologists say the sea animals flee the spill zone the way others would flee a forest fire. With thousands of gallons of oil contaminating their natural habitats, marine creatures press into oil-free waters.

"Their habitat is shrinking, tens of thousands of square miles are affected, and animals moving away from them," said Mobi Salangi, director of the Institute for Marine Mammal Studies. "There are changes in food, the food they eat and their prey."

3. I think more than just the gulf will be dying.
Maybe I'm being a henny penny, but with all of that oil just GUSHING daily, I can't see it being just a gulf problem.

I really am afraid that we have no idea how bad this catastrophe will turn out to be.

12. Imagine this thing spewing for decades.
We have quite possibly tapped into geological forces that we cannot now contain. I wonder if we have produced a civilization killer.

5. I worry about the methane being released through the water column. It must be one
hell of a carbonated drink.

7. Well if it is then you've no need to worry
Methane doesn't disolve in water and when it reaches the surface , given that its also lighter than air, it drifts skywards quickly.

11. but they're flaring off the nat gas
and burning off the oil as well. I wonder if anyone is monitoring the air for methane. Could make one helluva boom

13. "Methane,
which is also leaking from the Deepwater Horizon, poses another threat to underwater wildlife, as it attracts microbes that consume oxygen, and scientists said that if methane and microbe levels rise too much, they could create zones of so little oxygen that hardly anything could survive."

19. I don't think methane traveling up 1 mile of water column leaves with no trace. nt

6. Well, duh
The only thing that is going to fix this is oxygen. By burning or microbial action, all this oil has to get oxidized to return things to normal. If not, the Gulf of Mexico is going to become another Black Sea -- completely anoxic in the depths.

For those of you chemically inclined, calculate how much air it takes to oxidize crude oil. For those of you not so inclined, I will tell you -- 15 cubic feet of air for each ounce (28g) of oil. There are a LOT of ounces of crude oil out there, but I don't see many boats outfitted with air compressors aerating the water. Now that's something the Coast Guard could do, along with life vest inspections.

8. It keeps piling up. I feel like screaming 80% of the day.
My concentration is shot.

16. Everything reminds me of the gulf disaster even when I try to put it out of my mind
I turn on the water faucet and see the gusher... my Mr. Coffee reminds me of an oil pump. I fear for the birds at the feeder, as some will will migrate to the gulf this fall. I can't bring myself to eat the fish in my freezer. Just goes on and on like this.

17. All my actions seem futile in the shadow of what is transpiring.
It is so incredibly debilitating. My one solace is that I am treating those that I love with greater tenderness.

18. Yes, it's hard to find purpose or meaning
I worry what this is doing to the psyche of the children... I thought my nieces and nephew might need a diversion so took them out for lunch yesterday and we walked along the lake. Families of ducks were paddling along and all I could think of were the suffering, dying creatures of the gulf
