“Like a Work of Art”: Pristine Coral Reef Discovered Off Tahiti

Rare find is a stark reminder of what we’re losing to climate change.

A huge coral reef has been discovered off the coast of Tahiti in the Pacific Ocean’s “twilight zone,” offering hope that more pristine ecosystems are waiting to be discovered at unexplored depths.

Stretching along the ocean floor for nearly two miles, the reef, covered in rose-shaped corals, is one of the largest such discoveries at depths of more than 30 meters, where sunlight levels are much lower.

Scientists for the Unesco-led mission in French Polynesia said the reef, discovered in November, did not appear to have suffered bleaching events that had damaged neighboring reefs in shallower waters in 2019. During dives totaling 200 hours, researchers were able to witness the coral spawning, with some spanning two meters.

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

Researchers said more reefs were likely waiting to be discovered at these depths following improvements in diving technology, which had previously inhibited exploration.

“To date, we know the surface of the moon better than the deep ocean. Only 20 percent of the entire seabed has been mapped,” said Audrey Azoulay, Unesco’s director general.

Most of the world’s known coral reefs are at depths of 25 meters and above, with many facing the risk of collapse as the world’s oceans continue to heat. In September, a study found coral reef coverage had fallen by half since the 1950s because of global heating, overfishing, pollution and habitat destruction.

Speaking to the BBC Prof Murray Roberts, a marine scientist at the University of Edinburgh, said the discovery underscored the need to map similar reefs to make sure they can be protected in the future. “We still associate corals with the shallowest tropical seas but here we find a huge previously unknown coral reef system.

“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,” he said.

Further dives are planned in the coming months off the coast of Tahiti to continue investigations around the reef.

WE'LL BE BLUNT

It is astonishingly hard keeping a newsroom afloat these days, and we need to raise $253,000 in online donations quickly, by October 7.

The short of it: Last year, we had to cut $1 million from our budget so we could have any chance of breaking even by the time our fiscal year ended in June. And despite a huge rally from so many of you leading up to the deadline, we still came up a bit short on the whole. We can’t let that happen again. We have no wiggle room to begin with, and now we have a hole to dig out of.

Readers also told us to just give it to you straight when we need to ask for your support, and seeing how matter-of-factly explaining our inner workings, our challenges and finances, can bring more of you in has been a real silver lining. So our online membership lead, Brian, lays it all out for you in his personal, insider account (that literally puts his skin in the game!) of how urgent things are right now.

The upshot: Being able to rally $253,000 in donations over these next few weeks is vitally important simply because it is the number that keeps us right on track, helping make sure we don't end up with a bigger gap than can be filled again, helping us avoid any significant (and knowable) cash-flow crunches for now. We used to be more nonchalant about coming up short this time of year, thinking we can make it by the time June rolls around. Not anymore.

Because the in-depth journalism on underreported beats and unique perspectives on the daily news you turn to Mother Jones for is only possible because readers fund us. Corporations and powerful people with deep pockets will never sustain the type of journalism we exist to do. The only investors who won’t let independent, investigative journalism down are the people who actually care about its future—you.

And we need readers to show up for us big time—again.

Getting just 10 percent of the people who care enough about our work to be reading this blurb to part with a few bucks would be utterly transformative for us, and that's very much what we need to keep charging hard in this financially uncertain, high-stakes year.

If you can right now, please support the journalism you get from Mother Jones with a donation at whatever amount works for you. And please do it now, before you move on to whatever you're about to do next and think maybe you'll get to it later, because every gift matters and we really need to see a strong response if we're going to raise the $253,000 we need in less than three weeks.
