Arthur T Knackerbracket has found the following story:
Scientists in Siberia have discovered an area of sea that is "boiling" with methane, with bubbles that can be scooped from the water with buckets. Researchers on an expedition to the East Siberian Sea said the "methane fountain" was unlike anything they had seen before, with concentrations of the gas in the region to be six to seven times higher than the global average.
The team, led by Igor Semiletov, from Tomsk Polytechnic University in Russia, traveled to an area of the Eastern Arctic previously known to produce methane fountains. They were studying the environmental consequences of permafrost thawing beneath the ocean.
Permafrost is ground that is permanently frozen—in some cases for tens of thousands of years. According to the National Snow and Ice Data Center, permafrost currently covers about 8.7 million square miles of the Northern Hemisphere.
[...] permafrost is also present under the ocean. In 2017, scientists announced they had discovered hundreds of craters at the bottom of the Barents Sea, north of Norway and Russia. The craters had formed from methane building up then exploding suddenly when the pressure got too high.
In the latest expedition to chart methane emissions coming from the ocean, researchers analyzed the water around Bennett Island, taking samples of sea water and sediments. In one area, however, they found something unexpected—an extremely sharp increase in the concentration of atmospheric methane. According to a statement from Tomsk Polytechnic University, it was six to seven times higher than average.
They then noticed an area of water around four to five square meters that was "boiling with methane bubbles," the statement said. This could be scooped out with buckets, the researchers said. After identifying the fountain, the team was able to take samples directly from it. Methane levels around the fountain were nine times higher than average global concentrations.

While I appreciate your condescending tone toward AC, it should be noted that the boiling point of methane is quite low.
That is quite a bit lower than the temperature of permafrost (no citation, but if I'm wrong, please enlighten me). As such, it is reasonable to expect methane to be gaseous.
...or trapped in solution. Which might lead to effervescence.

Consider yourself condescended towards.
