KAUST's Ibn Sina Distinguished Professor Carlos Duarte has been awarded the prestigious Japan Prize for his pioneering research on blue carbon and marine ecosystems. Duarte's work demonstrated the significance of marine ecosystems like seagrasses, mangroves, and salt marshes in sequestering and storing carbon dioxide. He coined the term 'blue carbon' and has advised Vision2030 initiatives. Why it matters: This award recognizes the importance of KAUST's research in marine conservation and highlights Saudi Arabia's growing role in ocean-based climate change solutions.
KAUST researchers, partnering with the Queensland Government, discovered 34 previously unknown seagrass meadows in the Red Sea by tracking the foraging behavior of green turtles. They tagged and tracked 53 turtles, revealing that the turtles were approximately 20 times more reliable at identifying seagrass meadows compared to the Allen Coral Atlas. This method also proved to be significantly more cost-effective than traditional methods like airplanes with hyperspectral sensors. Why it matters: This study highlights a novel, cost-effective approach to mapping blue carbon ecosystems, crucial for carbon capture and marine habitat preservation, and provides valuable data for sustainability policies in the Red Sea region.
Researchers from KAUST and Beneath The Waves used camera tags on tiger sharks in the Bahamas to map the world's largest seagrass ecosystem, estimated at 92,000 km2. The study, published in Nature Communications, details how the sharks' movements helped validate spatial estimates of these blue carbon ecosystems. Carlos Duarte (KAUST) realized the potential of the shark movement data to map the extensive seagrass meadows in the shallow sand banks of the Bahamas. Why it matters: The innovative approach demonstrates a novel method for mapping and quantifying vast underwater ecosystems, crucial for understanding and conserving blue carbon sinks.
KAUST Professor Carlos Duarte gave a TED Talk on seagrass, highlighting their importance as marine ecosystems. His research focuses on Zostera marina, the first marine angiosperm to be fully sequenced. Duarte's team discovered massive clones of Posidonia oceanica in the Spanish Mediterranean, estimated to be 200,000 years old, which play a critical role in carbon sequestration. Why it matters: This research underscores the potential of seagrass in mitigating climate change and protecting coastal regions, emphasizing KAUST's contribution to marine science and environmental sustainability.
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.
Researchers from KAUST and the University of Padova studied how hyperoxia, or excessive oxygen supply, extends heat tolerance in marine ectotherms. The study, published in Science Advances, examined the role of photosynthetic organisms like seagrasses in producing oxygen in aquatic habitats. They found that increased oxygen availability helps coastal marine animals like crabs, sea cucumbers, and shellfish increase their resilience to rising temperatures. Why it matters: Understanding the interplay between oxygen levels and temperature tolerance can inform strategies for preserving marine ecosystems in the face of global warming.
Alejandra Ortega, a Ph.D. student in bioscience at KAUST, researches carbon fluxes of mangrove, seagrass, and macroalgae, focusing on estimating marine plants' contribution to blue carbon sequestration using metagenomes and eDNA barcoding. She aims to aid environmental managers and policymakers in better estimating blue carbon budgets for marine conservation. Ortega co-founded the Science Crossroads Initiative (SCI) at KAUST to explore the intersection of science with disciplines like philosophy, history, and the arts. Why it matters: This highlights KAUST's research into blue carbon sequestration and the university's focus on interdisciplinary initiatives to foster science communication and community engagement.
KAUST Professor Carlos Duarte has received the Carlo Heip Award for his contributions to marine biodiversity science. Duarte, director of KAUST's Red Sea Research Center, will receive the award in Montreal in May. Duarte is known for his work in biological oceanography and seagrass meadow ecology, contributing to blue carbon strategies. Why it matters: This award recognizes KAUST's leadership in marine ecological research and highlights the importance of Red Sea research for global conservation efforts.
