Southeast Asia is home to the Coral Triangle, a region renowned for its incredible marine biodiversity. This area hosts over 70% of the world’s coral species, making it the richest center of marine life and coral diversity on the planet. However, the coral reefs and urban oceans in this region are under threat from climate change. Yet, a new discovery of “super corals” in Southeast Asia offers a glimmer of hope for the future.
The ocean is a vital component of Earth’s life support system. It plays a crucial role in regulating the climate, absorbing significant amounts of carbon dioxide, and providing a vast array of food resources. However, factors such as population growth, rapid infrastructure development, and climate change are putting immense pressure on the ocean, particularly in Southeast Asia.
Super corals, found in urban oceans, have shown remarkable resilience to environmental stresses. These corals can teach us valuable lessons about protecting and conserving fragile coral reefs. The connection between a healthy ocean and healthy people is particularly evident in Southeast Asia, where the wellbeing of communities is closely linked to the health of the ocean.
Coral bleaching events are becoming more frequent and widespread, posing a significant threat to coral reefs. Scientists from the Earth Observatory of Singapore are investigating the impact of climate change on the ocean and exploring innovative solutions, such as artificial reefs, to support coral resilience. Could super corals be part of the solution to this global challenge?
Coral reefs are often referred to as the rainforests of the oceans due to their high biological productivity and biodiversity. They contribute up to 70% of the world’s oxygen supply. The Coral Triangle, spanning the Philippines, Papua New Guinea, and Indonesia, is the global epicenter of coral diversity, hosting a vast array of coral species and reef fishes.
Research conducted by scientists in Southeast Asia focuses on understanding how urban corals cope with challenging conditions. These corals, found near large urban centers, face pressures from urban development, sedimentation, and boat activity. Despite these challenges, some urban corals are thriving, offering insights into potential strategies for coral conservation worldwide.
Dr. Natasha Bhatia, a marine ecologist, and her team are studying urban coral reefs in the Straits of Singapore. They use ecological surveys and environmental loggers to monitor conditions affecting coral growth. Their research aims to understand the differences between urban and pristine reefs, as urban reefs need to be more stress-tolerant.
Urban corals have adapted to low light conditions due to high turbidity in the water. These corals have developed unique feeding strategies, extending their tentacles to capture food. Understanding these adaptations is crucial for saving fragile ocean areas where change is occurring rapidly.
To support coral reefs, an innovative project in Southeast Asia has launched the region’s largest artificial reef initiative. This project aims to attract coral growth in urban ocean areas. Engineers are experimenting with materials to encourage coral settlement, accelerating coral cultivation in marine environments.
At the St. John’s Island National Marine Laboratory, scientists are modeling future ocean conditions to assess the impacts of climate and human-induced stress on coral resilience. They manipulate environmental conditions in controlled aquariums to study potential future scenarios, aiming to scale up coral growth for research and restoration purposes.
The Allen Coral Atlas program is building the first global coral reef atlas to monitor coral health. This initiative allows scientists to track climate and human-induced impacts on coral reef systems. The program has achieved significant milestones, including a globally consistent set of maps of coral reef locations and compositions.
Since the mid-20th century, coral reef health has dramatically declined, with projections indicating that most coral reefs could disappear by mid-century if current trends continue. The decline is driven by planetary warming and the removal of vital marine creatures. Every organism plays a role in the ecosystem, and over-extraction has contributed to this decline.
Scientists at the Earth Observatory of Singapore are committed to enhancing the study of coral reefs and the surrounding ocean. The next decade is critical for understanding the ocean’s connection to climate, which affects the survival and well-being of people in Southeast Asia. By combining field and lab research, scientists are leading efforts to support important reefs like the Coral Triangle and other vital marine habitats worldwide.
A healthy ocean is essential for life on Earth, driving climate and weather, and supporting the greatest diversity of life. It is possible to take action to protect systems that create a healthy ocean, underpinning our prosperity and existence.

**Sanitized Transcript:**
Southeast Asia is home to the Coral Triangle, the planet’s richest center of marine life and coral diversity, where over 70 percent of the world’s coral species can be found. Many megacities sit alongside vast areas of urban ocean. Coral reefs and urban oceans are feeling the impact of our changing climate, but a new breed of super corals found in Southeast Asia are giving scientists hope.
The ocean is our planet’s life support system. It regulates the climate, absorbs huge amounts of carbon dioxide from the atmosphere, and provides us with vast sources of food. Population growth, rapid infrastructure development, our changing climate, and events happening far away in the polar regions are impacting the ocean and threatening all aspects of life across Southeast Asia.
What we’ve discovered from the super corals in these urban oceans and how they’ve built their resilience can teach us a lot about how we can protect and conserve fragile coral reefs. The connection between a healthy ocean and healthy people is nowhere more obvious than in Southeast Asia.
I’m concerned that in the next 5-10 years, bleaching events are becoming more frequent and widespread. We have much to learn and contribute to being part of the solutions for our changing oceans. Dive with scientists from the Earth Observatory of Singapore as they investigate the impact climate change is having on the ocean, explore engineering ideas for artificial reefs, and discover a coral species showing resilience to climate change. Could these super corals be part of the solution?
Most people don’t realize that oceans contribute up to 70% of the world’s oxygen supply, and coral reefs are often referred to as the rainforests of the oceans. They are crucial for biological productivity and biomass. The global epicenter of coral diversity is right here in Southeast Asia, in an area known as the Coral Triangle. This region spans warm tropical seas between the Philippines, Papua New Guinea, and Indonesia, where over 70% of the world’s coral species and a huge variety of reef fishes can be found.
Understanding how coral reefs react to global pressures, climate change, and increasing human activities is critical for understanding global ocean health and ultimately our own survival. Scientists at the Earth Observatory of Singapore monitoring the health of coral reefs in Southeast Asia have made an unusual discovery: while many coral reefs around the world are declining rapidly, some urban corals are showing resilience to human activity and climate-induced stresses. They call them super corals.
Urban oceans are coastal marine environments near large urban centers, typically adjacent to megacities with high population densities. Urban development and infrastructure place a lot of pressure on the marine environment, including increased sedimentation from land runoff and boat activity. In Singapore, one of the busiest ports in the world, the high volume of ship traffic adds pressure to the natural marine environments.
Local human activities are impacting the health of coral reefs across the world. In Southeast Asia, the combined impacts of climate-induced stress and human activity threaten ocean habitats. Increasing ocean temperatures can cause coral bleaching, and rapidly rising sea levels can drown certain types of reefs, particularly in urban areas where corals live under low light conditions due to poor water quality.
Marine research has largely focused on the declining health of pristine coral reefs. Now, scientists in Southeast Asia are focusing on urban coral reefs that are showing significant resilience, which could provide clues to save coral reefs in decline around the world.
Research aims to understand how corals cope and tolerate marginal conditions for growth, offering hope for the future resilience of reefs.
In a field trip, Dr. Natasha Bhatia, a marine ecologist, and her team are monitoring urban coral reefs showing resilience to environmental changes in the Straits of Singapore. They are using ecological surveys and environmental loggers to measure conditions affecting coral growth.
Corals are not just the engineers of underwater ecosystems; they are also living organisms. If we lose them, it can take multiple human generations to restore them. Protecting and conserving coral reef ecosystems is essential for global ocean health and our survival.
The team will conduct dives to assess the health of the reefs and install loggers to record environmental conditions. They aim to understand the differences in coral communities between urban and pristine reefs, as urban reefs need to be more stress-tolerant.
The local water quality and high turbidity mean that they are diving at the limits of where light can penetrate, forcing corals to adapt to low light conditions. The coral composition in urban waters differs from those on pristine reefs, reflecting their need for resilience.
The research team is also changing out data loggers that measure ocean temperature and sediment accumulation. Observations show that corals are thriving, with a diversity not seen on other reefs. These corals extend their tentacles to feed, supplementing their food source in low-light conditions.
Understanding ocean adaptation is crucial for saving fragile ocean areas where change is happening faster than adaptation can occur. The goal is to propagate these super corals and implant their resilience into more fragile coral reef systems to stabilize coral decline.
However, time is running out. The lessons learned from super corals can guide efforts to protect and conserve fragile reef systems.
Since the mid-20th century, there has been a dramatic shift in coral reef health, with about half of the world’s coral reefs either disappeared or in sharp decline. Projections indicate that most coral reefs could be gone by mid-century if current decline rates continue.
The decline is driven by planetary warming and the removal of vital marine creatures. Every organism plays a role in the ecosystem, and over-extraction has set in motion this decline.
To support ocean health and coral reefs in Southeast Asia, an innovative project has launched the country’s largest artificial reef initiative. This vertical structure aims to attract coral growth in urban ocean areas.
Engineers, including Professor Chu from Nanyang Technological University, are experimenting with materials to encourage coral settlement. The project seeks to accelerate coral cultivation in marine environments.
At the St. John’s Island National Marine Laboratory, scientists are modeling future oceans to assess the impacts of climate and human-induced stress on coral resilience. They manipulate various environmental conditions in controlled aquariums to study potential future scenarios.
Adjacent to the aquarium labs, coral nurseries are cultivating young urban corals for future reseeding of declining reefs. The goal is to scale up coral growth for research and restoration purposes.
By combining field and lab research, scientists in Southeast Asia are leading efforts to support important reefs like the Coral Triangle and other vital marine habitats worldwide.
One scientist, known for mapping the Amazon rainforest, is building the first global coral reef atlas to monitor coral health. The Allen Coral Atlas program allows tracking of climate and human-induced impacts on coral reef systems.
The late Paul Allen convened experts to envision global-scale science and technology for coral reefs. The partnership created a platform for mapping and monitoring coral health over time.
The Allen Coral Atlas has achieved significant milestones, including a globally consistent set of maps of coral reef locations and compositions. A bleaching monitoring system has also been launched to identify stressed corals and track their recovery.
Scientists at the Earth Observatory of Singapore are committed to enhancing the study of coral reefs and the surrounding ocean. The next decade is critical for understanding the ocean and its connection to climate, which affects the survival and well-being of people in Southeast Asia.
The research aims to fill gaps in understanding urban and extreme environments, helping to safeguard coral reefs and provide conservation protection. A healthy ocean is essential for life on Earth, driving climate and weather, and supporting the greatest diversity of life.
It is possible to take action to protect systems that create a healthy ocean, underpinning our prosperity and existence.
