A KAUST-led study published in Science found overwhelming evidence that man-made noise negatively impacts marine fauna and their ecosystems, disrupting behavior, physiology, and reproduction. The researchers assessed over 10,000 papers to demonstrate that noise pollution from shipping, fishing, and infrastructure development harms marine life from invertebrates to whales. They call for human-induced noise to be considered a prevalent stressor at the global scale and for policy to be developed to mitigate its effects. Why it matters: This research highlights the need to consider acoustic dimensions in ocean health restoration efforts, promoting management actions to reduce noise levels and allow marine animals to re-establish their use of ocean sound.
KAUST researchers from the Red Sea Research Center (RSRC) and Computational Bioscience Research Center (CBRC) found macroalgae DNA prevalent in the open ocean, up to 5,000 km from coastal areas. 69% of drifting macroalgae sinks below 1,000 m depth, sequestering carbon in deep ocean waters. The study used metagenomes generated by global ocean expeditions Tara Oceans and Malaspina, analyzed via KAUST's DMAP platform and Shaheen supercomputer. Why it matters: The findings confirm the role of macroalgae in carbon sequestration, highlighting their importance in blue carbon assessments for climate change mitigation and underscoring KAUST's contribution to environmental sustainability research.
KAUST Professor Carlos Duarte reflects on his ten years in Saudi Arabia after receiving the Japan Prize for his work on blue carbon. Duarte's research focuses on the role of oceans in combating climate change, particularly through the conservation of coastal ecosystems. Since joining KAUST in 2015, he has advised the Saudi government on environmentally friendly development, advocating for blue carbon strategies. Why it matters: Duarte's work is helping to shift perspectives on the ocean economy in the region, encouraging investment in marine ecosystem conservation and sustainability.
The G20 CORDAP and the Khaled bin Sultan Living Oceans Foundation (KSLOF) have signed a Memorandum of Understanding to collaborate on coral restoration education. The partnership aims to build capacity and enhance educational initiatives for coral restoration. Initial cooperation areas include education program development, learning program implementation, and knowledge sharing. Why it matters: This partnership leverages regional expertise to address a critical environmental issue, advancing coral restoration efforts through education and capacity building.
International ocean experts convened at COP25's Oceans Actions Day to discuss ocean and coastal climate actions, emphasizing their role in achieving sustainable development goals. Carlos Duarte, KAUST professor of marine science, highlighted the importance of conserving marine ecosystems like mangroves and seagrasses for carbon sequestration and coastal protection. He also noted Saudi Arabia's interest in promoting ocean and coastal climate actions under its G20 Presidency. Why it matters: The event underscores the crucial role of marine ecosystems in mitigating climate change and achieving global sustainability goals, with KAUST playing a prominent role in research and advocacy.
Princess Hala bint Khalid bin Sultan discussed the Khaled bin Sultan Living Oceans Foundation's marine preservation work at KAUST's Enrichment in the Fall program. The foundation focuses on research, education, and communication to preserve marine environments locally, regionally, and globally. Key projects include a five-year research expedition across 15 countries and the Mangroves Program in Jamaican and Bahamian schools. Why it matters: This highlights the ongoing efforts and commitment within Saudi Arabia to address critical environmental challenges in marine ecosystems through research and education.
Three KAUST students attended the 5th International Marine Conservation Congress in Malaysia, which brought together over 650 attendees. The conference focused on translating marine conservation science into real action, with participants discussing topics like the impact of above-water marine species and sustainable fishing practices. KAUST students presented their work and shared insights from the event. Why it matters: This participation highlights KAUST's commitment to addressing critical ocean conservation challenges and fostering international collaboration in marine science.
