So the "fizzy milkshake" is going by the wayside...
But what about rapid conversions of the calthrates, like what apparently happens in the icean with methane?
Could that be causing the "smokers" and other odd formations that seem to have seasonal attributes and incidence? Perhaps the calthrates "fail" releasing CO2 contaminated with minerals almost explosively, and if the idea you have of the rapidity of the great canyon systems, perhaps apocalyptically as well.
I wonder what it takes to get the calthrates to release the CO2 quickly...
Thanks again for the food for thought,
Ed
