This repost of a diary from 2 days ago describes the fact that there is 3000 times more natural gas coming out of the leak than oil. All of the gas is currently staying in the water because the ocean has the capacity to hold large quantities of methane in solution.
When methane breaks down it depletes oxygen in the water.
Then, when it continues to break down it produces hydrogen sulfate
After some discussions with people who are currently working to determine the extent of this undersea damage, I decided we need to revisit this topic: The damage of the massive amounts of Gas being released into the gulf is worse than the oil.
