Volcano Chex-Mix

The video Idahopicker did on his idea about the collapsed salt dome mentioned this paper –
Three generations of mud volcanoes on the Louisiana continental slope

So we found some more info –

Surface and Subsurface Manifestations of Gas Movement Through a N-S Transect of the Gulf of Mexico
http://tinyurl.com/kngsdpb

Large volumes of gas have vented through a north-south transect of the offshore northern Gulf of Mexico. An overview of surface and subsurface manifestations of this gas venting is presented.  This gas movement has caused extensive alteration of reservoired oils to the north of the transect which are estimated to have equilibrated with, or been gas washed by, as much as 30 volumes of gas for every volume of oil.

And blogger, Just Piper says “*Update* (BE ANGRY~ Who’s Fooling Who?!) BP And Our Govt Have Been Showing Us A Volcanic Vent, Not An Oil Spill (JUST MUST View!)”

Some great graphics are here:

  1. I have the Surface and Subsurface N-S Transect doc. Started reading it about a week ago but I got sidetracked. It was interesting. I was still looking for a conduit from the GoM to Hot Wells, LA. From what I remember it only discussed an area from Tiger Shoals in the north area of Green Canyon to Bush Hill in the south. And, a lot about gas washing that I had to struggle to understand. Thanks for the link to the paper mentioned in Idahopicker’s video. Now, I don’t have to go look for it. I suppose salt domes are like volcanoes in that they both use faults as a conduit to the surface. I’ve read some papers that discussed a water column present in the center. They have a higher temperature than most of their surroundings and gasses flow through them. Their description reminded me a lot of the description of seeps/vents in the GoM. The domes onshore and along the coast are upright, mountainous structures but on the outer continental edge they are prostrate…just as lots of folks have described them as being like squeezed tubes of toothpaste. I was thinking that might be where there might be a channel to Hot Wells. Where ever it might be, it passes through without changing the chemistry of the water. Anyway, that was my interest in the document. Now, I’ll have some weekend reading with the Three Generations of Mud Volcanoes paper 🙂

    • Good luck. I just got a sample peek at the 3 generations paper because I didn’t pay for it. If you find it online for FREE send a link here.
      The last link, the student thesis has GREAT graphics and a good view of the sea floor off Louisiana.
      We hadn’t discussed underground rivers yet so IPs video is useful for that topic.
      By the time we narrow in on the real culprit under Lake FUBAR it will probably be blowing up!

  2. Oh, I forgot! The one thing that I did understand and found a little scary was on the topic of landslides caused by gas seepage on the slopes. I’ll have to go back and finish reading that one.
