Antarctic Ocean Methane Release
Warming oceans and thinning ice destabilize gas hydrates, releasing methane.
Researchers found 20+ plumes between 130-790 feet deep in 2021-2023.
Methane measurements done via sealed seabed chambers over 1-2 days.
Seeps lower oxygen, acidity, and affect fisheries and carbon cycles.
Antarctic seeps first discovered in 2012 are now more common.
Methane is called a 'super pollutant' driving 30% of warming.
