This was caused by a large underwater landslide, known as the <a href="http://www.nrl.navy.mil/content.php?P=03REVIEW181" rel="nofollow">Storegga slide</a>. There is some discussion about what triggered the slide, but reduced shear strength of deposits due to the dissociation of methane clathrates is one of the likely culprits. Since I live on the 5 metre contour in Northern Scotland, this is a development I'll be watching with great interest.

I remember the reports from last year about the methane plumes in Siberian waters. Perhaps I should have said we are in deeper trouble. Deeper as in having more than one meaning.

This is not shallow water. Two things come to mind: First, our oceans are warming at a deeper depth and second, methane hydrate deposits on the sea floor are very sensitive to temperature change. We are in trouble... 150 to 400 metres…
