Methane Release from the Seabed?
Modified excerpt from: The Extinction Protocol August 17, 2012 –ARCTIC CIRCLE A German expedition research vessel and submersible lead by GEOMAR | Helmholtz Centre for Ocean Research to analyse the sea off the western shore of Spitsbergen -- to find whether the first methane hydrates in the sea bed are dissolving and what the consequences might be-- began this week in Reykjavik, building on research conducted here by marine scientists from Kiel in 2008 in which they found over 250 places where gas was escaping the sea bed. These spots lie directly on the border of the area of stable hydrates, which presumably are dissolving from the rim inwards. West of Spitsbergen methane gas is effervescing out of the seabed's transitional zones - between shallow shelfs and the deep sea at continental slopes - where huge amounts of methane hydrates are stored. These specific, ice-like compounds only form at low temperatures and under high pressure. When the water temperature directly abov...
