Ian MorseAiming to bolster conservation on the high seas, a team of marine researchers today released the first comprehensive survey of coral reefs in the high seas–the roughly two-thirds of the ocean outside of national jurisdictions.After combing through more than half a million observations of reef-building corals, the team identified 116 reefs located in the high seas.
Most of these corals live between 200 and 1200 meters beneath the surface, the researchers found. But a handful are found more than 2 kilometers deep.
And there are likely many more high seas corals still to be found, the authors note, as surveys have typically prioritized corals close to shore.
