Mon Mar 5, 2007 12:55PM EST LONDON (Reuters) - A team of British scientists has set sail on a voyage to examine why a huge chunk of the earth's crust is missing, deep under the Atlantic Ocean -- a phenomenon that challenges conventional ideas about how the earth works. The 20-strong team aims to survey an area some 3,000 to 4,000 metres deep where the mantle -- the deep interior of the earth normally covered by a crust kilometres thick -- is exposed on the sea floor. Experts describe the hole along the mid-Atlantic ridge as an "open wound" on the ocean floor that has puzzled scientists for the five or so years that its existence has been known because it defies existing tectonic plate theories of evolution. "We know so little about it," said Bramley Murton, a senior research scientist at Southampton's National Oceanography Center. "It's a real challenge to our established understanding of what the earth's surface looks like underneath the waves," he told Reuters by telephone from the brand new, hi-tech British research ship RRS James Cook. Mid ocean ridges are places where new oceanic crust is born, with red-hot lava spewing out along the seafloor. What scientists are keen to know is whether the crust was ripped away by huge geological faults, or whether it never even developed in the first place. The primary motivation for the project was to understand how the earth continues to evolve. "The area that we are looking at is part of a mountain range that spans thousands of square kilometres, but we are beginning to realize that there are probably millions of square kilometres where the ocean floor is missing," Murton said. The six week mission, led by geophysicist Roger Searle of Durham University and Chris MacLeod of Cardiff University's School of Earth, Ocean and Planetary Sciences, will recover sample cores of rock by drilling into the mantle using a rig lowered on to the sea floor. Asked if the discovery posed a threat to the environment, Murton replied: "It's not problematic for the earth because it is a natural earth process -- but in terms of knowing how the earth works and how the world is put together it is important." Murton also said the expedition would shed light on the composition of sea water amongst other initiatives. Crust formation is a fundamental mechanism of the earth which affects the chemistry of the world's oceans.

(Over time the earth has grown. Check it out!) Brilliant. Always wondered why subduction seemed so rare, and so rarely near continents. However, have you figured out what process ("plasma"?) he credits with the growth of the Earth? Is it nuclear? Is it akin to what drives the growth of a Red Giant? Or hasn't he figured this part out yet?
It appears to be on my kitchen floor.
Asteroid strike??

I thought so too. Shrink the size of the earth, and the continental crusts all fit together. This is an amazing insight. However, have you figured out what process ("plasma"?) he credits with the growth of the Earth? Is it nuclear? Is it akin to what drives the growth of a Red Giant? Or hasn't he figured this part out yet? I think that BIG QUESTION remains to be answered. He has some theories, though. He claims that this plantary expansion is not just an earth phenom, but is evidenced by the crusts of every other observable planet and even the moon. So, whatever is happening is effecting all large masses. Might it have something to do with a stretching out of the fabric of space-time?

So earth expands in size as hell fills up to capacity...is that your theory?

Nah.........I was thinking of the 'heat' element.
Here's an interesting question: I've seen people claim the reason dinosaurs were so big in the past is because gravity was less. After all, why are there no gigantic dinosaurs today? If the Earth was smaller in the past, would the gravity be less? Might that not be an explanation?

It reminds me of the scene in the South Park movie where Kenny goes to Hell and the numbers sign is 240,000,000,000,000,000 and is spinning upward so fast you can't read the numbers. Then he goes to Heaven and the sign reads 241 and is clicking so slow it looks like it's stuck in molasses.
