I Followed Teams of Scientists on a Mission to Save Australia’s Good Barrier Reef — Here’s What I Discovered
From a marine rehabilitation cruise line to the region’s only carbon-adverse resort, these corporations are coming up with revolutionary applications to regrow coral.

On a late January day at Opal Reef, about 30 miles off the northeastern coast of Queensland, Australia, anything strange was afoot. I was standing on the deck of a 64-foot catamaran amid plastic tubs wired with electrodes. They had been complete of reside coral fragments, gradually becoming heated in seawater.
“It’s a fast anxiety test,” explained John Edmondson, marine biologist and operator of Wavelength Reef Cruises. Created to mimic the warming waters that have been bleaching the corals in this area for years, it is a single of quite a few ongoing experiments that will assistance the group safeguard the Good Barrier Reef from climate adjust.
I was with a group of scientists from the University of Technologies Sydney on a single of their daylong analysis outings, through which they gathered information and samples from the submarine gardens. One particular scientist was hunting into how algae photosynthesize and feed nutrients to host corals. A different was studying bacteria, although two Ph.D. candidates captured coral gases, which assistance figure out the corals’ anxiety levels (the scent of sulfur is a telltale sign of problems).
Barely 200 feet away from this floating laboratory, dozens of guests from yet another Wavelength vessel snorkeled and dove on the crescent-shaped reef although mastering about conservation from their personal group of researchers.
Tourism, meet science. This is what a go to to the Good Barrier Reef appears like now, exactly where analysis and commerce function side by side to locate options.

Wavelength is a single of six industrial operators in the northern reef among Cairns and Port Douglas involved in the Coral Nurture System, a joint endeavor among scientists and the travel operators whose livelihoods rely on the reef’s survival. The plan is an work to rehabilitate marine habitats, mainly making use of very simple masonry nails and Coralclips, stainless-steel devices invented by Edmondson and his marine biologist wife, Jenny. They attach coral fragments to broken bommies, an Australian term for reef outcrops. The approach appears a lot like propagating cuttings in a garden, except in this case the garden is 1,429 miles lengthy and household to three,000 person reef systems, numerous hundreds of difficult and soft corals, and some 9,000 species of marine creatures.

Given that the program’s launch in 2018, additional than 70,000 corals have been planted, with an impressive survival price of 85 %. In November 2021, some of the new corals spawned for the 1st time. One particular planted coral fragment can produce hundreds, if not thousands, of corals more than a lifetime, mentioned professor David Suggett, cofounder — with Edmondson and Emma Camp, yet another UTS professor — of the Coral Nurture System.

To defend the reef, scientists will have to 1st fully grasp it. There have been 5 mass bleachings considering the fact that 1998, which suggests that — astonishingly — the Good Barrier Reef has now lost half of its reside corals. “Everyone is going back to fundamentals,” Suggett explained. “We have to fully grasp how corals develop, what things make them develop, all this information that is been overlooked. Till the bleachings, we didn’t have to have these tools, mainly because the reef was capable of recovery.”
From Cairns, I flew to the Whitsunday Islands, some 300 miles south. Marine biologist Johnny Gaskell has been busy planting corals and seeding larvae about the archipelago. Lots of reefs about these 74 islands had been broken by Cyclone Debbie in 2017. Working with the “coral IVF” and nursery approaches of larvae management, Gaskell and his group aim to restore what was lost.
Gaskell and biologist James Unsworth, of sustainable tour operator Ocean Rafting, picked me up on an inflatable speedboat from my hotel, Elysian Retreat, the region’s only carbon-adverse resort. Its ten solar-powered cabins hug the otherwise pristine southern shore of Lengthy Island, a gateway to the Whitsundays.
We sped along to Manta Ray Bay on nearby Hook Island. It is a single of eight web-sites in the Whitsundays exactly where reefs are receiving a assisting hand. Gaskell pointed out man-produced frames floating deep beneath exactly where transplanted corals are repopulating the bay.

We also stopped at the Daydream Island Resort & Living Reef, a low-rise, whitewashed home exactly where Gaskell gave me a tour of some land-primarily based coral nurseries ahead of displaying me the reef itself: 656 feet of coral that kind a lagoon about the home that he had been hired to program and establish as the resort’s showpiece in 2014. Topic to the identical volatile circumstances as the ocean itself, this exceptional biosphere — now household to additional than one hundred species of fish and 80 species of coral — is a bellwether of the wellness of the Good Barrier Reef as a complete.
Someplace in this microcosm sits “Steve,” the really 1st coral Gaskell planted. Given that then, coral development has been so prolific that he struggles to recognize his protégé in the wonder wall of sculptural types. Steve has lived by way of a cyclone, bleachings, and waves of toxic agricultural sediment flushed into the sea by tropical downpours.
“There’s been ups and downs — it is been a true roller-coaster ride for Steve,” Gaskell mentioned with a smile. “He became the guinea pig for coral restoration and then had to survive Cyclone Debbie.” If Steve is certainly on the front lines of the reef’s future, then his potential to flourish is fantastic news for us all.
