Glad to see the new Greenpeace expedition info, but also must comment on bigGdelta's methane release info. Yes. You can sink a ship or potentially knock a plane out of the sky with enough methane release from the sea floor. They've replicated it enough under laboratory conditions that it's rather convincing. Eric, you called this first (I think).

Indeed I have. (Wow, watching Discovery Channel helps! :biggrin2:)

But hydrates are not only found in say...The Berrmuda Triangle, but why does it only take place there?

On a side note, more ships disappeared between the Taiwan Straits than in the Bermuda Triangle.

very large concentrations of methane hydrate are found in this area, although by rights, this should be more common in the gulf of mexico as this is where most of the cold seeps (think ice worms here people) are found. BTW saw something a few weeks back blaming the permian extinction on a large scale release of methane from undersea hydrates (after a global temp rise of 5 degrees---the methane added another 5).

Its fashionable now to blame every event in geologic history on hydrate release (In the same way that not so long ago it was fashionable to blame each event on a bolide impact). This was first suggested in 1995to explain coincident negative carbon and oxygen stable isotope excursions. Both excursions are "approximately" instantaneous and hydrate release is a very compelling (albeit inherently untestable) way to explain it.

Given that, the P/T event doesn't really have any of the attributes that really make hydrate release a compelling argument.
