Diving to 600m, researchers find reefs full of octopus, lobster and fish, raising hopes for corals’ survival amid rising sea temperatures

Scientists operating a submersible have discovered deep-sea coral reefs in pristine condition in a previously unexplored part of the Galápagos marine reserve.

Diving to depths of 600 metres (1,970ft), to the summit of a previously unmapped seamount in the central part of the archipelago, the scientists witnessed a breathtaking mix of deep marine life. This has raised hopes that healthy reefs can still thrive at a time when coral is in crisis due to record sea surface temperatures and ocean acidification. It also showed the effectiveness of conservation actions and effective management, they said.
