NEW CORAL REEF DISCOVERED IN PACIFIC OCEAN - UNDAMAGED BY CLIMATE CHANGE

Chandrayee Roy Choudhury, Canada:

Scientists have discovered a pristine, three-kilometre-long reef of giant rose-shaped corals off the coast of Tahiti, in waters of the southern Pacific Ocean thought to be deep enough to protect it from the bleaching effects of the warming ocean.

The reef, which lies at depths of more than 30 metres, probably took around 25 years to grow. Some of the rose-shaped corals measure more than two metres in diameter.

"It was magical to witness giant, beautiful rose corals, which stretch for as far as the eye can see. It was like a work of art," said French photographer Alexis Rosenfeld, who led the team of international divers that made the discovery.

Most of the world's known coral reefs are in warmer waters at depths of up to 25 metres, the United Nations Educational, Scientific and Cultural Organization (UNESCO) said. The reef off Tahiti lies in the "twilight zone" 30 to 120 metres below the surface where there is still enough light for coral to grow and reproduce.

UNESCO says the newly discovered reef is one of the largest in the world.
