Massive release of methane gas from the seafloor discovered for the first time in the Southern Hemisphere

Gas hydrate is an ice-like substance formed by water and methane at depths of several hundred meters at the bottom of our oceans at high pressure and low temperatures. Methane is a potent greenhouse gas, roughly 25 times more potent than carbon dioxide, and it is estimated that methane frozen in these sediments constitute the largest organic carbon reservoir on Earth. The fact that methane gas has now started leaking out through gas hydrate dissociation is not good news for the climate.
