All for one article...methane...amazon

[tridean]

Hi Laura and others. Doing a search through this forum often sends me on different adventures and I came across Laura's article written 24th June
http://laura-knight-jadczyk.blogspot.com/2010/06/all-for-one-and-one-for-all.html

I tried to see if there was any mention of the Amazon jungle on this board and methane but there wasn't, but the article reminded me of another article I read a few years ago (I can not remember where I read it, who wrote it, sorry), well before I knew of this forum, but it essentially described how the ocean floors surrounding the Amazon jungle especially are covered in massive amounts of methane deposits created from the rotting floor of the Amazon jungle which is constantly washed out to sea. This article suggested that the amount of this methane deposit simply from the Amazon alone is so large that a disruption to it will be catastrophic to the whole planet. I do remember feeling quite horrified and resigned to death, by the severity of the catastrophe predicted.

I just wonder though, that Laura mentions the Gulf of Mexico and seeing as that is near the Amazon, it may be related..not sure?

That's pretty interesting, Dingo. Along that line, I remember reading an article a year or two ago about a hole in the earth's crust in the Atlantic more or less off the coast of Brazil. Maybe somebody can find it and post it. It really caught my eye and I thought "huh?! what is THAT?"

Hi Laura, I think you're talking about this article:

I was trying to find a follow up to this, but so far I don't see too much about this since..

Yeah, that's it. Funny that we heard no more about it. I do remember seeing a map that showed the location. Isn't there a funny image of the earth that graphically represents the magnetism or gravity of the planet or something like that? I think it shows up there, too.

Anyway, I'm still pushing that book that Shijing found: "Cataclysm" by Allan and Delair. It is MOST interesting in relation to this topic. Highly recommended.

This one from here?

Have a look at this gravity image of the earth:

Looks like this is the location here:

Mid-ocean ridges are a fascinating component of our planet's armour plating. Mid-ocean ridges are the place where new oceanic crust is born, with red-hot lava spewing out along the spreading axis as seafloor spreading progresses. However, the mechanisms by which this occurs are still not well understood by scientists - hardly surprising when you consider that mid-ocean ridges are located thousands of metres below the surface of the ocean.

Scientists have discovered a large area thousands of square kilometres in extent in the middle of the Atlantic Ocean where the Earth's crust seems to be missing entirely. Instead, the mantle - the deep interior of the Earth, normally covered by crust many kilometres thick - is exposed on the seafloor, 3000m below the surface. It has been described as being like an open wound on the surface of the Earth. What scientists don't know is whether the ocean crust was first developed, and then ripped away by huge geological faults, or whether it never even developed in the first place.

In March-April 2007, a team of scientists from Durham University, Cardiff University and NOCS will board the RRS James Cook to visit this special area of the Mid-Atlantic Ridge, which is called the Fifteen-Twenty Fracture Zone (FTFZ for short - the map on the left shows where this is located).

The scientific team on board the ship is led by Prof. Roger Searle from University of Durham, Dr Chris MacLeod (University of Cardiff) and Dr Bramley Murton (NOCS).

Above is the image of the Mid-Atlantic Ridge. You can see how the ridge is broken up into segments by fractures running roughly perpendicular to the ridge axis. The red dot shows the area where the team on board the ship will be working. Bathymetric image courtesy GEBCO.
