Corals In New Caledonia Are Adapting To Future Ocean Conditions

Coral reefs around the world suffer from climate change As the oceans are warming and acidifying, our beloved coral prospects are not optimistic. However, researchers in New Caledonia made important discoveries.

The team at Sydney Institute of Technology (UTS) is trying to find limiting habitats and find coral resilient hotspots. What they found was the community of diverse coral reefs "Super Coral" that grew under hot, acidic and hypoxic conditions, predicting the future of our ocean.

This expedition took place in the remote lagoon system of Bouquet New Caledonia in 2016 and showed that there may be a way to survive adapting to corals. This discovery is a joint project between Sydney Institute of Technology Sydney and the International Development Institute (NY), recently announced in a scientific report.

"The existence of living corals under this normally deadly triple condition is comparable and even exceeds what is predicted by climate change.It is that we have some new corals that can stick to the future Giving hope ", Dr. Camp says the climate member will change the cluster of Sydney Institute of Technology (C3)

They discovered that coral crowds in the lagoon system show high abundance (number of seed = 20) and coverage (24-35% of lagoon sites). The calcification rates of major species of the lagoon population (Acropora formosa, Acropora pulchra, Coelastrea aspera, Porites lutea) are almost the same or nearly declining. 30 to 40%

The promotion of coral respiration and the high particulate organic content in the lagoon sediment indicate adaptation to these three temperature, oxygen and pH changes due to heterotrophic plasticity. This means that the corals lose some photosynthetic algae during the bleaching process and still get nutrients from the food.

This semi-enclosed lagoon understands the adaptability of corals to complex climate scenarios and provides the team with a unique opportunity system to function as a coral population that endured extreme environmental conditions.

Tropical lagoons and coral reefs in New Caledonia are excellent examples of very diverse coral reef ecosystems and are one of the three most extensive coral reef systems in the world. They are the world's most diverse collection of coral reefs, ranging from mangroves to seaweed and a range of coral reef habitat continuous habitats with diverse coral and fish species, leading to important oceanic gradients. They are still showing the perfect ecosystem with a healthy highest predator population and large and diverse big fish species. From coral reefs of different ages, from living coral reefs to ancient fossil reefs, they have unique natural beauty and are providing important sources of information on Oceania's natural history.

Standard (vii): The most advanced natural phenomena or natural beauty: New Caledonia's tropical lagoons and coral reefs are considered one of the most beautiful coral reef systems in the world, due to the relatively small areas. Various shapes and shapes. It extends from a wide range of double barrier systems, from offshore coral reefs and coral islands to reticulated coral reefs on the west coast. The richness and diversity of the landscape and coastal background gives a unique aesthetic appeal of superior quality. This beauty continues beneath the surface, coral diversity, huge coral structure, coral reef arch, dramatic display of caves, and even under big cracks.

In contrast to the brilliant rainbow color of the growing coral, the coral death caused by a process called bleaching tends to look dull and unlikely. Bleached coral reefs usually appear as unlimited white corals, eventually becoming dead brown corals. But in New Caledonia, Vevers discovered something else. The corals that he captured were illuminated by fluorescence as they slowly and reliably left them. The crew used this underwater SVX camera system to capture this moment - this technology can take 360 ​​degree images underwater. "In the past, people were unable to reach the right place at the right time," Vevers said. "I was blown away ... I have never seen such a beautiful thing, but it is already dead."
