KAUST's Professor Carlos M. Duarte has been awarded the Japan Prize for his research on blue carbon ecosystems and their role in climate solutions. Duarte's work has demonstrated that these ecosystems, though small, store a large percentage of carbon in marine sediments. He has also advised Saudi Arabia on marine conservation and influenced global ocean policy. Why it matters: This award highlights the importance of KAUST's contributions to sustainability research and marine conservation, aligning with Saudi Arabia's Vision 2030 and the Saudi Green Initiative.
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 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.
KAUST's coastal wetlands contain 90 hectares of protected mangroves that support over 240 bird species and various marine life. These mangroves, predominantly Avicennia marina, sequester CO2 at a rate 30 times higher than other forests, burying it in sediment. This "blue carbon" storage occurs because the lack of oxygen in mangrove soils prevents the degradation of organic matter. Why it matters: This highlights the critical role of Red Sea mangroves in carbon sequestration and biodiversity, emphasizing their importance for regional climate change mitigation.
KAUST's Professor Carlos Duarte received the 2019 Ramon Margalef Prize in Ecology from the Generalitat of Catalonia. The award recognizes Duarte's research into 'blue carbon' and its impact on climate change mitigation. Duarte highlighted the role of KAUST and collaborators in enabling his research achievements. Why it matters: The recognition of a KAUST professor for contributions to marine ecology highlights the university's growing role in environmental research and its impact on global climate change strategies.
