KAUST researchers are studying corals in the Red Sea and Arabian Gulf that are more tolerant of high temperatures. They are mating corals from different parts of the world, assuming that the offspring will be more heat-resistant. Using a commercial coral spawning system, the researchers can time coral spawning to cross colonies that would not naturally cross. Why it matters: This research aims to identify genes responsible for temperature resilience and use selective breeding to increase coral resilience in the face of rising ocean temperatures.
KAUST researchers are using 3D printing with a novel calcium carbonate ink to create coral support structures that accelerate coral restoration. Their approach, named 3D CoraPrint, involves printing coral microfragments onto the structure, offering a head start for reef recovery. Two methods were developed: printing a mold for reproduction and direct printing for customization. Why it matters: This eco-friendly technique provides a potentially scalable solution to combat coral reef degradation, leveraging advanced materials and fabrication for ecological conservation in the region and beyond.
KAUST researchers collaborated with international scientists to propose a nature-based adaptive approach for coral restoration, published in Nature Reviews in Earth & Environment. The review emphasizes enhancing specific components of the coral holobiont to maximize the natural adaptive capacity of corals to survive climate change. It advocates for customized protection approaches based on the reef's degradation, location, and traits. Why it matters: This research offers a critical roadmap for preserving coral reefs, which are vital ecosystems threatened by climate change, by leveraging the corals' natural adaptive mechanisms.
KAUST researchers from the Red Sea Research Center are studying mesophotic reefs (40-150m deep) as potential climate refuges for corals threatened by marine heatwaves. These deeper reefs experience less heat and light stress compared to shallow-water corals. Advanced tools like submarines and robots are now enabling the study of these previously neglected ecosystems. Why it matters: Understanding the resilience of Red Sea corals could provide crucial insights for global coral reef conservation strategies amid climate change.
The KAUST Reefscape Restoration Initiative (KRRI) observed the first-ever mass synchronized coral spawning in the northern Red Sea at NEOM’s Shushah Island. In March 2023, KRRI launched on-the-reef restoration work at Shushah, propagating nearly 5,000 corals from a dozen species, nearly half of their 2023 annual target. KRRI is testing various coral propagation techniques and nursery designs, aiming to produce half a million corals per year. Why it matters: This initiative is a major step towards coral reef restoration in the Red Sea, aligning with Saudi Arabia's sustainable development goals.
