Major study shows resilience of Maldives reefs
US-based research group Coral Reef CPR, which has been studying a multitude of locations throughout the Maldives, has reported that some regions have demonstrated a remarkable resilience to elevated water temperatures, whereas others have been subjected to stress from other causes.
Bleaching in the Maldives was first reported in 2015, but most areas rebounded quickly. As the unusual weather patterns associated with an El Niño event persisted throughout 2015 and worsened in 2016, reefs bleached again. Coral Reef CPR measured the temperatures at a depth of 10 metres in lagoon, channel and outer reefs on Baa atoll and South Male Atoll, and found them to be abnormally high and steadily increasing between March and April that year.

Temperatures on exposed outer reefs ranged from 32-33° C, while lagoon reefs climbed to 35° C and higher, which was 2-5° C above the normal annual maximum. Using a highly accurate Castaway CTD (hand-held, deployable temperature metre), the team also measured temperature profiles from the surface to 40 metres of depth which showed a complete breakdown of cooler deep currents and absence of a thermocline. They reported that at the same time, “the surface of the sea was like glass and the water was gin clear,” allowing for a greater penetration of harmful UV radiation. “Together,” wrote Dr Andrew Bruckner of Coral CPR, “these conditions were a recipe for disaster.”
According to their research, Coral Reef CPR found that bleaching of the most sensitive corals started in March 2016, and by mid-April entire shallow reef systems throughout the country were stark white. Some corals resisted bleaching initially, especially the massive boulder corals such as Porites, but the water continued to warm. By the time the summer monsoon finally kicked in during mid-May, nearly every coral was either fully bleached or a vivid fluorescent colouration (yellow, purple, red or blue) as the coral animal produced photo-protective pigments to shield its tissue from too much sunlight.
Bleached coral can recover if environmental conditions return to normal relatively quickly, but the prolonged duration of the 2016 bleaching event overwhelmed many of the more sensitive species. Shallow lagoon reefs, reef flat and reef crest communities above five metres of depth sustained catastrophic losses, with up to 80 to 95 percent loss of coral in the hardest hit areas, particularly the dominant branching and table acroporids.
To gain more insight on the country-wide extent of bleaching impacts, Coral Reef CPR surveyed more than 80 reefs on eight different atolls in central and northern Maldives. While most emergent reefs in both fore reef and lagoon areas had become “a graveyard of coral skeletons” by August 2016, not all reefs were equally affected and even the hardest hit areas had survivors.

Pocillopora, another common form of branching coral, showed a higher survival rate in the shallow reef flats losing between 50 to 75 per cent of its cover – a large percentage, but significantly lower than other species. Other reefs throughout the country, especially those in outer exposed areas and submerged deep reefs which were dominated by massive boulder corals as opposed to the more fragile acroporids, lost between 10 to 20 percent of their corals, a much higher rate of survival.
Although initial observations suggested that the situation was ‘ominous’, Coral Reef CPR found that a more detailed examination of the reefs yielded a number of positive surprises. Of particular significance were individual colonies of certain species that failed to bleach, despite being located adjacent to other colonies that had fully bleached. Some of the corals produced vivid fluorescent pigments, which appeared to offer protection to these colonies.
The team found that some reefs provided a refuge from the bleaching, with high numbers of surviving corals on channel reefs and submerged reefs, known locally as thillas, where there is much more water movement. Coral mortality was also found to be reduced on outer reefs that are exposed to high wave action. These areas still lost most of their branching and table corals, but they are dominated by boulder corals, especially massive Porites corals which are much slower-growing and tend to be long-lived, with some colonies estimated to be between 500 and 1000 years in age. Although many of these larger corals appeared to lose some tissue, very few of them actually died, and the team began to see signs of tissue recovery, observing that all the reefs considered to be bleaching “refuges” had high numbers of boulder corals as well as the more fragile branching and plating acroporids.
Many of the Maldives’ atolls, especially on their western side, have small islands that contain their own lagoon, forming a structure that resembles a micro-atoll. These lagoons tend to be fairly shallow at only 5-15 metre deep, and the sandy bottom is covered with hundreds of small coral bommies and patch reefs. These areas often support unique, unusually large boulder, plating or foliaceous (leaf-like) corals that form the framework of the reef and are colonised by a high diversity of corals, especially acroporids. Within these areas, Coral Reef CPR identified more than 30 species of Acropora that survived the 2016 bleaching event. These environments tend to have lower visibility, which may explain why they provided a refuge from bleaching.

In all reef environments, the team found much higher survivorship of corals on reef slopes. In many cases, the steep part of the slope was littered with hundreds of broken Acropora branches, fragments that had been detached from larger colonies on the top of the reef and carried down the slope. The base of these reefs contained larger, intact, branching, digitate (finger-like) and table acroporids in good condition.
Remarkably, the studied sites had unusually high numbers of coral recruits and one to two-year-old juvenile corals that had resisted bleaching. These included most of the acroporids and other species that sustained very high mortality during the 2016 bleaching event. Dr Bruckner notes that the presence of these corals provides evidence that coral reefs in the Maldives are still very resilient and are likely to recover quite quickly.
“Reading some of the recent negative reports from the Maldives highlights some of the gaps in understanding, variations between reef survey techniques and importance of evaluating a large number of reefs and not drawing conclusions from a small sample size,” reports Dr Buckner.
“This is particularly important as the geological foundation of the islands and reef systems of the Maldives does not permit small sample sets of data to be extrapolated for the whole country.”

The Maldives contains a large number of reefs which are distant from populated areas. However, there is a great deal of concern regarding environmental degradation associated with a recent “building boom” around the islands. The team also found that other reefs, especially those around North Male Atoll and Ari Atoll have been badly damaged by a severe outbreak of Crown of Thorns Starfish (COTS), cushion starfish (Culcita sp.) and coral-eating snails (Drupella sp.). This outbreak of “corallivores” began prior to the bleaching event in 2016 and has continued after the bleaching ended, causing the loss of coral to be misinterpreted, according to Coral Reef CPR.
“During 2017,” writes Dr Bruckner, “a number of other marine biologists told us about reefs that are undergoing bleaching again. However, when we examined these locations, the damage caused by the corallivores was misinterpreted as bleaching and, further, our temperature meters and NOAA satellite data have recorded temperatures that are within the normal range.”
Noting that some observations may have been carried out with non-scientific equipment, he adds that “we strongly discourage the use of recreational diving computers as a measure of accurate water temperature.”
In conclusion, Dr Bruckner writes that “there have been large scale changes to the reef systems throughout the country as a result of the 2016 coral bleaching event, and these have been compounded locally by other human and natural stressors. However, these reefs show multiple signs that indicate they are resilient to these stressors, and in absence of high numbers of corallivores and unsustainable coastal development and other human impacts, they are undergoing rapid recovery.”

There are surfers who follow a game plan. And then there’s Mason Ho. A blend of style icon, surfing heritage and technical standout, Ho has built a career doing things his own way, usually at full speed, often upside down and regularly pushing the limits of performance across challenging reef breaks and unconventional equipment.
This is exactly why the Four Seasons Maldives Surfing Champions Trophy feels like a natural fit.
For Ho, part of the appeal lies in the opportunity to surf through different eras of the sport – an event where adaptability matters as much as performance, where board choice can shape a heat, and where surfers are recognised not only for power but for style, flow and reading the moment.
From unlikely barrels to impossible lines, few surfers in the modern era have built a career on instinct in quite the same way. Whether riding single fins, twins, thrusters or something less conventional, Ho approaches surfing less as a fixed discipline and more as an open-ended exploration, a quality that continues to define his style and his impact on the sport.
“I try to approach it like I’m living in another time,” says Ho. “If it’s single fin day, I think about guys like Michael Peterson, my dad and Uncle D. Then when it’s twin fin day, I start thinking about MR and all the stories my dad used to tell me. That’s what makes this event so unique. You get to step into different eras of surfing throughout the week.”
Hosted by Four Seasons Resort Maldives at Kuda Huraa, the invitation-only event brings together six of surfing’s most celebrated athletes to compete across three iconic board divisions: single fin, twin fin and thruster. Set against the clean, high-performance walls of Sultans, the format rewards adaptability as much as power, style as much as strategy, and timing as much as talent.
“Mason brings a completely unique energy to this event,” says Mark Winson, Event Director. “You genuinely never know what he’s going to do next – whether it’s on a wave, on a board, or in the channel between heats. But underneath all of that personality is one of the most naturally gifted surfers on the planet.”
Ho, who returns for his second Surfing Champions Trophy appearance, said the experience of competing in the event once before has only increased his anticipation for 2026.
“Last time I didn’t really know what to expect,” he says. “This year I’ve got a slight clue, which makes me even more excited to come back healthy. The waves have been super fun the last few years, the resort is amazing and there’s always a really cool crew around. I can’t wait to get back out there.”
Mason joins Kai Lenny as the first two athletes announced for this year’s event. The remaining 2026 competitor line-up will be revealed in the coming weeks, with updates shared across surfingchampionstrophy.com and Four Seasons Resort Maldives at Kuda Huraa channels.
Where Champs Come to Surf
First staged in 2011, the Four Seasons Maldives Surfing Champions Trophy has become one of surfing’s most distinctive invitation-only events, bringing six celebrated athletes to Sultans to compete across single fin, twin fin and thruster divisions. Past names include Mark Occhilupo, Taj Burrow, Josh Kerr, Kelly Slater, Joel Parkinson, Michel Bourez, Carissa Moore, Maya Gabeira and more. After Bourez’s dramatic 2025 win, complete with a comeback from injury and the event’s only perfect 10, this edition has plenty to live up to. With Kai Lenny and Mason Ho now confirmed, it is already shaping up to be beautifully unpredictable.
The Garden-Island Base at Kuda Huraa
Just 25 minutes by speedboat from Malé, Four Seasons Resort Maldives at Kuda Huraa gives the event its warm, garden-island base, with easy access to North Malé Atoll’s best breaks and a longstanding collaboration with Tropicsurf. Between heats at Sultans, guests can expect post-surf stories, recovery rituals, sunset gatherings and the rare chance to swap board talk with world champions in boardshorts. Serious surfing, very unserious tan lines.

Anantara Dhigu Maldives Resort has announced a new collaboration with rrreefs to introduce an innovative 3D-printed clay reef installation within the resort’s surrounding lagoon – a meaningful step in the resort’s continued commitment to marine conservation and regenerative travel experiences in the Maldives.
Supported by Edelweiss and help alliance, both part of the Lufthansa Group, the project combines advanced reef restoration technology with nature-inspired design to help foster coral regeneration, encourage marine biodiversity and support the long-term resilience of fragile reef ecosystems.
The installation features 13 flower-shaped clay reef structures named Theyra Maa, meaning ‘13 Flowers’ in Dhivehi, symbolising renewal, growth and the flourishing of marine life within the resort’s lagoon ecosystem.
Brought to life through the expertise of the rrreefs team, including Co-Founder Josephine Graf, Head of Production Mauro Bischoff and Marine Ecologist Dr. Julia Spaet, alongside Dr. Gerrit Nanninga, a Research Fellow at the Department of Earth and Environmental Sciences, Ludwig Maximilian University of Munich, the installation is their collective vision which combines innovative design, scientific research and a shared passion for protecting and restoring coral reef ecosystems for future generations.
“We designed the Theyra Maa reef structures using durable and sustainable materials, with fired terracotta clay as the primary component, complemented by steel and a minimal amount of concrete to ensure structural integrity,” said Mauro Bischoff, the visionary behind the project.
He added, “Every element of the design has been carefully considered to support coral growth. The flower-inspired forms create gentle water movement around the structures, helping coral larvae settle more effectively. The 3D-printed clay also features a unique microstructure with tiny cavities between each layer, providing sheltered spaces where young coral larvae can attach and grow while being protected from predators. Achieving the right level of porosity in the clay is equally important, as it encourages the formation of beneficial biofilms that support coral settlement while helping maintain a healthy balance within the surrounding ecosystem.”
Crafted from natural clay using state-of-the-art 3D-printing technology, the reef structures have been thoughtfully designed to emulate the complexity of natural coral habitats. Over time, the installation is expected to provide a nurturing environment for coral fragments, reef fish and marine life to flourish, contributing to the restoration of vibrant underwater ecosystems surrounding the island resort.
“This partnership with rrreefs is particularly exciting as it marks the organisation’s first direct collaboration with a resort, bringing together shared values and a genuine passion for ocean conservation. The Theyra Maa installation is a truly unique project, combining innovative reef restoration technology with meaningful environmental action. Opportunities like this are still relatively rare, and we are proud to work alongside rrreefs and our partners to support coral reef recovery and strengthen the resilience of our coastal ecosystems for future generations,” said Oriana Migliaccio, Resident Marine Biologist at Anantara Dhigu Maldives Resort.
Nestled within the turquoise waters of South Malé Atoll, Anantara Dhigu Maldives Resort has long championed environmentally conscious hospitality, creating immersive guest experiences that celebrate and protect the natural beauty of the Maldives.
“At Anantara, we believe luxury and sustainability should exist in harmony,” said Jason Kruse, Complex General Manager at Anantara Dhigu Maldives Resort. “Our partnership with rrreefs reflects our ongoing dedication to preserving the marine environment that makes the Maldives so extraordinary. Through innovation, collaboration and purposeful action, we hope to inspire greater awareness and lasting positive impact beneath the surface.”
rrreefs brings together marine science, engineering and regenerative design to create scalable reef restoration systems tailored to vulnerable coastal environments.
“The inspiration behind rrreefs comes from a deep passion for the ocean and a determination to take meaningful action against the rapid decline of coral reefs, which are among the first ecosystems at risk from climate change,” said Josephine Graf, Co-Founder of rrreefs. “Through projects like Theyra Maa, we aim to support reef resilience and regeneration while raising awareness of the urgent need to protect our marine environments. Together with Anantara Dhigu and Edelweiss Air, we are creating a project that not only supports coral reef regeneration, but also demonstrates the power of cross-industry partnerships in protecting our oceans for future generations.”
As sponsor of the initiative, Edelweiss together with help alliance, continue to support sustainability-focused projects across its destination network, reinforcing a shared vision for more responsible tourism and environmental stewardship.
“Protecting natural ecosystems and creating educational opportunities are closely connected. Through this project, we support not only the restoration of coral reefs but also environmental education and sustainable future prospects for local communities, especially young people. Together with our partners, we want to contribute to lasting positive change for both people and nature,” said Anja Trestl, Corporate Development Manager at Edelweiss.
The Theyra Maa installation forms part of Anantara Dhigu’s broader sustainability journey, offering guests at the resort and its neighbouring sister properties, Anantara Veli Maldives Resort and Naladhu Private Island Maldives the opportunity to connect more deeply with the destination while contributing to the preservation of one of the world’s most precious marine environments.
