    It's because water holds the spring/summer heat. Land can't do this except a negligible bit. Heat only goes down 2-3 m (7-10 feet) into land over the spring/summer. That's the same as the top 1-1.5 m (3.3-5 feet) of a lake, sea or ocean. It's tiny. So any lake deeper than 5 feet is going to store more spring/summer heat than any land anywhere. For cold places like Alaska in this video the water in the ground below got frozen over 85,000 years of the last glaciation period "ice age" perhaps as much as 500 m deep (depends on what surface temperature was there) so it's an impermeable soil & ice "concrete" (like your garden and sand/gravel driveway in January in Canada, an axe will bounce off it). The last 10,000 years it's been slowly warming and the ice thawing so it's just wet soil, and methane (CH4) in the pores under geologic pressure is seeping up. Clearly, it doesn't need humans fracturing ("fracking") it with water pressure to force it up here, it's got enough of its own pressure to reach the surface. As the surface has been warming much more the last 50 years the ice will be thawing more, deeper and letting more CH4 seep up. How long it takes depends mostly on how much ice there is to melt like if there's 0.4% ice it'll melt to 160 metres down over the next 270 years but if there's 10% ice it'll melt to 160 metres down over the next 3,100 years. It makes a big difference. The further down it melts the more CH4 will stop being held back by an ice/soil cap above it and will bubble up. Pretty simple.

    Methane hydrates are certainly an interesting phenomena.

    I wonder...as the Earth warms and this becomes more common, would this be a good sport for area kids with canoes and flaming arrows to set these gas pockets aflame, that way, the methane would be immediately comverted into less infraredred-opaque gases.

    @DeathIzurfriend I would tend to think not. The volume of gas being released appears to be too high and too steady to be from bacteria alone.

    who's got a lighter?

    Maybe the lake is above an old Dinosaur graveyard.

    this is amazing i cause i have been reading an article that explains how this could b the reason behind the disappearances in the bermuda triangle on the salem-news website
    the article is called "How Brilliant Computer Scientists Solved the Bermuda Triangle Mystery"

    that looks like bubbles coming up from a scuba diver
