The moon could be affecting how much methane is released from the Arctic Ocean seafloor, a new study finds.

The tides, which are controlled bythe moon, affect how much methane is released from seafloor sediments: Low tides mean less pressure and more methane released, while high tides create more pressure, and therefore less methane emission.

The research was conducted in the west-Svalbard region of the Arctic, with the findings published Oct. 9 in the journalNature Communications.

“It is the first time that this observation has been made in the Arctic Ocean. It means that slight pressure changes can release significant amounts of methane. This is a game-changer and the highest impact of the…
