KAUST scientists have successfully expanded coral spawning through controlled systems, producing approximately two million eggs from six coral species this season to support reef research. Researchers at KAUST's Coastal and Marine Resources (CMR) Core Lab developed facilities that replicate environmental signals to trigger spawning beyond natural seasonal cycles, enabling year-round access to gametes and larvae. This program represents the first successful implementation of shifted phase coral spawning in Saudi Arabia. Why it matters: This breakthrough provides unprecedented opportunities for advancing Red Sea reef restoration and marine science, allowing for continuous study of coral early-life resilience.
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.
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.
National Geographic's new four-part series "Chasing Answers" highlights KAUST's emergence as a global scientific research hub. The documentary focuses on KAUST's research in areas of global concern like human need, social advancement, and environmental sustainability. Specific episodes cover alternative energy solutions, underwater internet, coral spawning, and feeding the world's growing population. Why it matters: The series showcases the growing role of Saudi Arabia and KAUST in addressing critical global challenges through scientific research and technological innovation.
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.
