Escape of methane gas from the seabed along the West Spitsbergen continental margin [PDF]

, 2009
More than 250 plumes of gas bubbles have been discovered emanating from the seabed of the West Spitsbergen continental margin, in a depth range of 150-400 m, at and above the present upper limit of the gas hydrate stability zone (GHSZ).
