Warm waters of South Pacific nestle a coral colony, unmatched in size, off the grimly far away island of Malaulalo. The coral, a Pavona clavus, measures 34 meters across, 32 meters long, and 5.5 meters tall, making it 12 meters larger than America’s previous record holder from American Samoa.

An underwater cathedral, this giant carcass of coral was captured in vivid shots during a National Geographic Pristine Seas expedition. Leading a team of videographer Manu San Félix, the group accidentally came across the coral while probing an area that was classified as a shipwreck.

“It is impressive to see something so big and so old-around 300 years old-bouncing back through such significant changes in the environment,” according to San Félix...

The largest coral ever recorded has been found by scientists in the southwest Pacific Ocean. The mega coral – which is a collection of many connected, tiny creatures that together form one organism rather than a reef – could be more than 300 years old. It is bigger than a blue whale, the team say.

It was found by a videographer working on a National Geographic ship visiting remote parts of the Pacific to see how it has been affected by climate change.

“I went diving in a place where the map said there was a shipwreck and then I saw something,” said Manu San Felix.

He called over his diving buddy, who is also his son Inigo, and they dived further down to inspect it.

Seeing the coral, which is in the Solomon Islands, was like seeing a “ca...

On the sidelines of the UN Oceans Conference, held from 27 June to 1 July 2022 in Lisbon, Portugal, the governments of Portugal and Kenya co-organised a forum on investment in the sustainable blue economy. One of the outcomes of the initiative was an increase in the capital of the Global Coral Reef Fund (GCRF). With two new commitments totalling US$18 million, the GFCR’s capital now stands at US$170 million.

The larger of the two contributions is from Builders Vision, an impact platform offering philanthropic tools and versatile investments to individuals and organisations committed to sustainable development. Builders Vision is investing US$5-10 million in the RFCG’s equity fund, as well as contributing US$5 million to the RFCG’s catalytic grant fund.

A new University of Wisconsin-Madison study has implications for predicting coral reef survival and developing mitigation strategies against having their bony skeletons weakened by ocean acidification. Though coral reefs make up less than one percent of the ocean floor, these ecosystems are among the most biodiverse on the planet – with over a million species estimated to be associated with reefs. The coral species that make up these reefs are known to be differently sensitive or resilient to ocean acidification – the result of increasing atmospheric carbon dioxide levels. But scientists are not sure why.

In the study, researchers show that the crystallization rate of coral skeletons differs across species and is correlated with their resilience to acidification.

“Many agencies keep...

Harmful to ocean and aquatic life, microplastics make up the nearly three percent toxic pollutants in shallow, tropical waters where corals flourish. These toxic chemicals bring huge detrimental impact on reef health, and a new study reveals 4 million pounds of them may be stored in coral skeletons every year.

After 18 months of exposing corals in the lab to microplastics, researchers were able to put a number on how much of the tiny fragments of plastic are stored in them.

“Our study clearly indicates that microplastics are yet another human-made stress factor for corals and that they are very likely to contribute to further deterioration of coral reefs on our planet,” lead author Jessica Reichert reported.

The study conducted by this team of scientists from the University Giess...

Climate change presents some detrimental obstacles to fragile coral reefs such as heat-related bleaching, but new research shows that some coral communities are evolving to become more heat tolerant as ocean temperatures rise. A new study investigated the impact of heat stress on the Phoenix Islands Protected Area (PIPA), and discovered that despite 75 percent of the coral reef being damaged by a heatwave in 2003, a later heatwave in 2010 was far less damaging. 

A 2015-2016 heatwave that was twice as strong as the 2003 example was almost half as damaging, with just 40 percent of coral cover loss. 

“We’re seeing areas that were devoid of corals after 2002-2003 that are now flourishing with most of the original species,” said study lead author Michael Fox, a coral reef ecologist at...

Warming seas are driving many species of marine life to shift their geographic ranges out of the tropics to higher latitudes where the water is cooler. Florida’s reefs will not be able to make that northward move, however, as they will be caught between intolerably hot tropical waters and increasingly frequent water-cooling cold snaps, according to new findings from Florida Institute of Technology, the U.S. Geological Survey, and several other institutions to be published June 22 in Nature’s Scientific Reports.

Populations of the main species of reef-building corals are already in dire condition, to the extent that they are listed under the Endangered Species Act. With no where to go, the corals will decline even more drastically.

Corals are colonies of animals related to sea anemon...

If you were lucky enough to take a tropical beach vacation more than 30 years ago, you were likely amazed at the underwater world you could explore with a snorkel and mask. Since then, underwater enthusiasts often find reefs are a disappointment, with bleached, broken, and dead corals more prominent than live colorful ones. 

Coral restoration projects are making a difference. They’re not just for guests of the hotels that sponsor them but make a difference for the entire planet. As you plan a post-pandemic beach vacation, lend the oceans a helping hand by choosing a resort that participates in coral reef restoration programs.

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study.

“This is similar to a blood test to assess human health,” said senior author Debashish Bhattacharya, a Distinguished Professor in the Department of Biochemistry and Microbiology in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick. “We can assess coral health by measuring the metabolites (chemicals created for metabolism) they produce and, ultimately, identify the best interventions to ensure reef health. Coral bleaching from warming waters is an ongoing worldwide ecological disaster...

A 10-year-old from Maui converted her backyard into a native plant nursery to help save coral reefs. Abby Rogers, a volunteer with the nonprofit Coral Reef Alliance, has grown over 900 native plants in the past few months to trap sediment at Wahikuli, which runs into the ocean and smothers coral reefs.

Typically, CORAL purchases the plants and hosts volunteer planting days at restoration sites.

However, due to COVID-19 restrictions, volunteers were needed to grow the plants at home.

“I really wanted to help the environment, but all I could ever think of was using a straw or bringing my own bags to the store,” said Rogers.

“My mom read about the CORAL project in a newspaper article and suggested it to me.”

Rogers is one of 100 volunteers who signed up to grow 25,000 ...
