The waves that run along shallow continental shelves are much larger than those over the deep ocean, and so the force applied by the standing waves is also larger in shallow water. (newscientist.com)
The increased wave action reaches down and stirs up sediments on shallow continental shelves, releasing radium and other chemicals that are carried up to the surface and swept away into the open ocean by currents such as the Transpolar Drift. (sciencedaily.com)
Under this scenario, most of the clathrate deposits in the arctic (both tundra and shallow continental shelf deposits) could be released into the atmosphere in a fairly short period of time (less than a century), implying a rate of outgassing that makes 100 times present estimated levels a vast underforecast.
