Bizarre Ecosystem Discovered More Than Two Miles beneath Arctic Ocean

Scientists discovered towering mounds made of crystallized methane on the Arctic Ocean floor off Greenland's coast, reaching record depths of 3,640 meters below the surface. These "frozen reefs" release the tallest methane gas flares ever recorded, extending 3,300 meters into the water, while hosting unique chemosynthetic creatures that survive through chemical reactions rather than sunlight. The dynamic structures collapse and reform over time, creating ecosystems that may be connected to hydrothermal vents and require protection from potential deep-sea mining activities.
