What is a methane clathrate?
Quick Answer
A methane clathrate is an ice-like solid in which methane molecules are trapped inside cages of water molecules. It is found in deep ocean sediments and under permafrost.
The Full Story
Methane clathrates, also called methane hydrates, form under high pressure and low temperature conditions. They are sometimes described as burning ice because they can release methane gas if warmed or depressurized. Huge deposits are thought to exist on continental margins and beneath Arctic permafrost, but extracting them is technically difficult and environmentally risky. Scientists study clathrates because they may influence climate, seafloor stability, and future energy resources.
