Invisible Giant: World's Largest Waterfall Hidden Beneath Arctic Ocean

• The Denmark Strait cataract, located between Greenland and Iceland, is the world's largest waterfall, entirely hidden beneath the Arctic Ocean.
• Unlike surface waterfalls, it forms when dense, cold Nordic Seas water plunges 3,500 meters beneath lighter Atlantic water, a depth more than three times that of Angel Falls.
• Its volume of water flow surpasses the Amazon River's discharge, making it the largest by both height and flow, yet it remained unknown for centuries.
• Scientists discovered it through instruments detecting temperature, salinity changes, and unusual current speeds, confirming its massive scale.
• This underwater waterfall plays a critical role in the Atlantic Meridional Overturning Circulation, influencing global climate, heat distribution, and marine ecosystems.
