The tidal loading issue is related to the cohesive sediments, which react non-elastically to changes in the "load". The pathways feeding the seeps can open and close in response to that pressure forcing, even at significant water depths. Precipitation of hydrate or carbonate can also cause fluid pathways that shuttle fluids/gas to seafloor to shut down. [21:41:22] @merlin - could well be, it just seems interesting that there are a lot of big ones, and then a lot of small ones.
