A Massive #Methane Reservoir Is Lurking Beneath the Sea

Scientists have found a methane reservoir below the #permafrost seabed of the #LaptevSea—a reservoir that could suddenly release large amounts of the potent #GreenhouseGas

"Methane bubbles regularly reach the surface of the Laptev Sea in the East #Siberian #ArcticOcean (#ESAO), each of them a small blow to our efforts to mitigate climate change. The source of the methane used to be a mystery, but a joint Swedish-Russian-U.S. investigation recently discovered that an ancient gas reservoir is responsible for the bubbly leaks.

"Methane in the Laptev Sea is stored in reservoirs below the sea’s submarine permafrost or in the form of methane hydrates—solid ice-like structures that trap the gas inside. It is also produced by microbes in the thawing permafrost itself. Not all of these sources are created equal: Whereas microbial methane is released in a slow, gradual process, disintegrating hydrates and reservoirs can lead to sudden, eruptive releases.

"Methane is escaping as the Laptev’s submarine permafrost is thawed by the relative warmth of overlying seawater.

"With an even stronger greenhouse effect than #CarbonDioxide, methane releases into the atmosphere could substantially amplify global warming."

A huge ice floe🧊 - 58x30 km - is drifting southward in the Fram Strait! - reported by METNorway Ice Service yesterday.

We have tracked its journey across the Arctic Ocean back to its "birthplace" in the #LaptevSea, autumn 2021.
