Rare, Pristine Coral Reef Found Off Tahiti Coast

A team of scientists has explored a rare, pristine coral reef off the coast of Tahiti .

What struck Hédouin was that the corals looked healthy and weren't affected by a bleaching event in 2019. Corals are tiny animals that grow and form reefs in oceans around the world.Globally, coral reefs have been depleted from overfishing and pollution. Climate change is also harming delicate corals — including those in areas neighboring the newly discovered reef — with severe bleaching caused by warmer waters. Between 2009 and 2018, 14% of the world's corals were killed, according to a 2020 report by the Global Coral Reef Monitoring Project.

Giant pristine coral reef discovered off TahitiCoral 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.

A 'Pristine' Reef of Rose-Shaped Corals Was Just Found Off The Coast of Tahiti Scientists have discovered a vast reef of 'pristine' rose-shaped corals apparently unharmed by climate change in deep water off the coast of Tahiti , UNESCO announced Thursday. What a treat.

Sprawling Coral Reef Resembling Roses Is Discovered Off TahitiAn underwater mapping project took an unexpected twist off the coast of Tahiti , where deep sea explorers said this week that they had discovered a sprawling coral reef resembling a bed of roses that appeared to be largely unscathed by climate change . Close the door Am I supposed to feel happy that at depth there’s currently unaffected areas? Because, it’s just a matter of time. Hi, I am a structural engineer from Iran who have many ideas. I have summarized some of my ideas on my twitter(I suggest look at the idea of generating electricity by gravity). I want to work with companies and investors. Do you want to cooperate?

Surreal Coral Rose Garden Discovered Off TahitiThe coral reef , which exists in much deeper water than other reefs, is surprisingly healthy.

Discovery of 'pristine' coral reef near Tahiti could help save dying coral reefs around the world, scientist saysThe marine science community is buzzing with excitement after the discovery of a rare stretch of coral reef in pristine condition off the coast of Tahiti and the answers it could hold to save other dying species around the world. Just please don't say where it is. Humans will eventually destroy it while being 'tourists'! michikokakutani Lack of humans? And now some jerky people are going to go in and try to destroy it “just because they can“

Rare Coral Reef Is Discovered Off Tahiti’s Coast Scientists have found a rare and pristine 2-mile stretch of coral shaped like rose petals off the coast of Tahiti Must be global warming Leave it alone! now that it’s found we should have that destroyed before the end of the decade

Majority of US States Pursue Nuclear Power for Emission Cuts What struck Hédouin was that the corals looked healthy and weren't affected by a bleaching event in 2019.Read full article Victoria Gill - Science correspondent, BBC News January 20, 2022, 2:48 PM · 2 min read Marine explorers have discovered a "pristine" 3km (2-mile) coral reef at depths of 30m (100ft) off the coast of Tahiti, French Polynesia.adding that only 20 percent of the world's seabed has been mapped.mesophotic zone — from the Greek words for middle and light — where the algae that coral depends on for survival can still grow but where light penetration is significantly diminished, scientists said.

Corals are tiny animals that grow and form reefs in oceans around the world. Globally, coral reefs have been depleted from overfishing and pollution. Dr Julian Barbiere, from Unesco, said there were probably many more of these ecosystems "we just don't know about". Climate change is also harming delicate corals — including those in areas neighboring the newly discovered reef — with severe bleaching caused by warmer waters." Most of the world's known reefs have been found at depths of up to 25 meters and the UN heritage body said the Tahiti reef could suggest there are more areas of healthy coral in the ocean's unmapped"twilight zone". Between 2009 and 2018, 14% of the world's corals were killed, according to a 2020 report by the Global Coral Reef Monitoring Project. Twilight zone Unesco director general Audrey Azoulay said the "remarkable" discovery extended our knowledge of "what lies beneath". The newfound reef, stretching 2 miles (3 kilometers), was studied late last year during a dive expedition supported by UNESCO. “You can see them as far as the eye can see,” he 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). French underwater photographer Alexis Rosenfeld said it had been "magical to witness giant, beautiful rose corals stretching as far as the eye can see". (UNESCO/Alexis Rosenfeld/1 Ocean) French Polynesia suffered a significant bleaching event back in 2019, but this newly discovered reef does not appear to have been significantly affected. Exploring such depths posed a challenge: the deeper a diver goes underwater, the shorter amount of time can be safely spent at each depth. 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. 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. The reef is in a spot where many researchers haven't spent a lot of time in, said former National Oceanic and Atmospheric Administration oceanographer Mark Eakin. Warming threat Starfish can also ravage corals by eating them. The ocean around Antarctica is doing its best to help Earth's atmosphere, and it turns out it's doing a better job than previously thought. "We still associate corals with the shallowest tropical seas but here we find a huge previously unknown coral reef system..

A new NASA-sponsored study says the Southern Ocean is a very effective "carbon sink," meaning the water absorbs much more carbon from the air than it releases. Researcher Matthew Long explains more about the study. We need to get out there to map these special places, understand their ecological role and make sure we protect them for the future. In October, the Global Coral Reef Monitoring Network said dynamite fishing, pollution, but mostly global warming had wiped out 14 percent of the world's coral reefs between 2009 to 2018. “We’ll be seeing more of these discoveries as the technology is applied to these locations,” said Eakin. “We may find some bigger ones somewhere, but I think this is always going to be an unusual reef. 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.” The recent volcanic eruption in Tonga that triggered tsunami waves across the Pacific has not affected the reef off Tahiti, said Hédouin. A single bleaching event in 1998 caused by warming waters wiped out 8 percent of all corals. “That can destroy or really impact the coral reef,” he said.

Hédouin hopes the research can help experts understand how the reef has been resilient to climate change and human pressures, and what role these deeper corals might play in the ocean ecosystem." The discovery provided an important insight into ocean biodiversity, Dr Barbiere said. More dives are planned in the coming months. “We know very little about the ocean, and there’s still so much that needs to be recorded, needs to be measured,” said Julian Barbière, the head of UNESCO’s marine policy and regional coordination. "So the next stage is to find what species live around this type of reef.

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 know every detail of Mars, every detail of the moon and certain planets,” Mr.
