Under the Denmark Strait, which separates Greenland and Iceland, an underwater waterfall is formed as cold, denser seawater drops from the Greenland Sea into the slightly warmer Irminger Sea. The cold water falls more than 3.5 km, at least three times the height of Angel Falls. Known as the Denmark Strait Cataract, this underwater waterfall carries around five million cubic metres of water per second. The Denmark Strait Cataract was discovered in 1989.
