Lazs,that is correct.

angus.. I doubt that your nets have seen the entire ocean floor"
That is correct. But they see more and more, and unveil more and more.
So what do you conclude when you scan an unknown seabed and find a volcano? Ohhh it must have been there since yesterday????????
"our" nets BTW run around a highly volcanically active area on the N-Atlantic rift. And the area is impressively large, added by the databases of both foreign ground as well as our neighbour countries. Norway, for one, is a very big fishing nation.
"our" ships also do their acts outside Canada, as well as in the Bering sea. All data from bottom/drag nets is recorded, and there is lots of stuff being discovered all the time.
Peaks are tagged (since they rip nets if they are sharp, actually the net-rip areas are specially tagged), as well as crevasses, danger zones (i.e. the debris from WW2 naval engagement, - we were fishing close to HMS Hood for instance).
And most importantly, the best fishing catches are tagged, logged, registered, analyzed, calculated etc etc..
So, to get back on spot your volcanoes are not popping up from an explored seabed, it's the other way around, they are slowly being exposed by multible data from many sources, be it fishermen or scientists. Well, these were practically your words. Or do you have such a belief that anything you see for the first time is brand new?
Now, to methane and the famous cow farting theory.
1. The record breakers there are still the USA. Oh did I say "breakers" like in "ze breaking of ze vind
"
2. Before blaming the cows for the whole deals we must remember 2 things, A & B...
A: This is a man- made business for man's food. Or do you think that burgers grow from trees?
B: Before clearing the ground for cows and other practical ruminants, the ground was loaded with wild ruminants, such as i.e. the N-American buffalos.....
In short, I'd be sceptic there, but the release of methane from moorland that has been canalized (for cheap animal food or pasture) is however stunning and well into embarresment....
