Coral reefs are among the ocean's most threatened ecosystems - vulnerable to pollution, rising sea temperatures and the change in chemistry caused by carbon-dioxide emissions dissolving in the water.

Rare, pristine coral reef found off Tahiti coastDeep in the South Pacific, scientists have explored a rare stretch of pristine corals shaped like roses off the coast of Tahiti. The reef is thought to be one of the largest found at such depths and seems untouched by climate change or human activities. Sometimes there is good news somewhere on this planet.

'Magical' massive coral reef discovered deep below surface in Tahiti 'twilight zone'Humans and climate change are killing the world's reefs. The latest discovery of one of the largest deepwater reefs offers hope they can survive.

Pristine coral reef discovered in deep water off the coast of TahitiA spectacular coral reef has been found between 35 and 70 metres below sea level near Tahiti, and it seems to be in good health despite the global biodiversity crisis And she's poking it already. Should have kept it quiet. The absence of human visitors has probably helped.

Pristine coral reef unblemished by warming oceans found off TahitiScientists have discovered a pristine, 3-km (1.8-mile) long reef of giant rose-shaped corals off the coast of Tahiti, in waters thought to be deep enough to protect it from the bleaching effects of the warming ocean.

It is one of the largest discovered at that depth, says the United Nations Educational, Scientific and Cultural Organization, which led the mission. Dr Julian Barbiere, from Unesco, said there were probably many more of these ecosystems "we just don't know about". Deep in the South Pacific, scientists have explored a rare stretch of pristine corals shaped like roses off the coast of Tahiti. "We should be working to map them and to protect them," he said. The reef, discovered in"pristine" condition in November, stretches nearly two miles long and 200 feet wide. Twilight zone Unesco director general Audrey Azoulay said the "remarkable" discovery extended our knowledge of "what lies beneath". (Alexis Rosenfeld/@alexis. The reef was found in November, during a diving expedition to a depth known as the ocean's "twilight zone" - part of a global seabed-mapping mission called the Seabed2030 Project . By mapping more of the ocean, at even greater depths, researchers hope to understand the best ways to protect and manage these rich ecosystems.

French underwater photographer Alexis Rosenfeld said it had been "magical to witness giant, beautiful rose corals stretching as far as the eye can see". The reef is thought to be one of the largest found at such depths and seems untouched by climate change or human activities. Divers document a massive coral reef found in the Pacific Ocean's"twilight zone. "It was like a work of art," he added. Fish 'whoops and growls’ heard on restored reef Coral reefs are among the ocean's most threatened ecosystems - vulnerable to pollution, rising sea temperatures and the change in chemistry caused by carbon-dioxide emissions dissolving in the water. “When I went there for the first time, I thought, ‘Wow — we need to study that reef. Prof Murray Roberts, a leading marine scientist from the University of Edinburgh said the discovery brought home how much we still have to learn about the ocean. "We know the surface of the moon better than the deep ocean. "We still associate corals with the shallowest tropical seas but here we find a huge previously unknown coral reef system. What struck Hédouin was that the corals looked healthy and weren't affected by a bleaching event in 2019. “There are also benefits to coral reefs which are not always that obvious,” says Barbière.

"As shallow waters warm faster than the deeper waters we may find these deeper reef systems are refuges for corals in the future. We need to get out there to map these special places, understand their ecological role and make sure we protect them for the future. Globally, coral reefs have been depleted from overfishing and pollution." The finding, as UNESCO said, is"highly unusual," as coral tends to grow in depths of up to about 82 feet, where the water is warmer and receives more light." There is currently "no evidence" this reef had been damaged by those pressures and, Dr Barbiere said, its unusual depth was one reason it remained in such a "very good state". Story continues "Generally we find them at shallower depths," he told BBC News, because the algae that lives within the bodies of corals needs light. Between 2009 and 2018, 14% of the world's corals were killed, according to a 2020 report by the Global Coral Reef Monitoring Project. "But here we're in a part of the ocean that is [further] from land, so there is less sediment that ends up in the ocean here. But divers now have the necessary tools to dive longer at greater depth, and are planning to continue studying the area.

" The discovery provided an important insight into ocean biodiversity, Dr Barbiere said. Unlike most of the world’s mapped corals, which are found in relatively shallow waters, this one was deeper — between 115 feet (35 meters) to 230 feet (70 meters). "We know that about 25% of marine species can be found in coral reefs," he said. "So the next stage is to find what species live around this type of reef. The team was equipped with special tanks and did 200 hours of diving to study the reef, including taking photographs, measurements and samples of the coral." "It was like a work of art," he said." The coming months will see further investigation. Another of the specialist divers, Dr Laetitia Hedouin, from France's National Centre of Scientific Research, said: "We would expect a reef such as this to take around 25 years to grow and develop like this. “We’ll be seeing more of these discoveries as the technology is applied to these locations,” said Eakin.

"We think that deeper reefs may be better protected from global warming. This highly unusual discovery is a great leap forward for. "So the discovery of this reef in such a pristine condition is good news and can inspire future conservation.” The recent volcanic eruption in Tonga that triggered tsunami waves across the Pacific has not affected the reef off Tahiti, said Hédouin."
