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 is collaborating with Coastline Company to convert Red Sea seaweed, specifically Sargassum, into valuable commodities. This initiative addresses the environmental hazard of decomposing seaweed blooms and promotes local employment and a circular economy. KAUST is exploring the use of Sargassum to produce fabric raw materials, alginate for food, biostimulants for agriculture, and fucoidans for therapeutic applications, processing it in a biorefinery manner. Why it matters: This project aligns with Saudi Arabia's sustainability priorities and demonstrates the potential of marine biomass in various industries, including fashion through collaboration with the Saudi Fashion Commission and PYRATEX®.
KAUST's Professor Carlos Duarte contributed to sequencing the genome of Zostera marina (eelgrass), work published in Nature. The research identifies gene loss and adaptation mechanisms related to the plant's transition from land to marine environments. Eelgrass developed salt resistance, which could inform selective breeding for salt-tolerant food crops. Why it matters: Understanding the eelgrass genome can help in conservation efforts and provide insights into plant adaptation to climate change and marine environments.
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.
The Saudi Ministry of Environment, Water, and Agriculture (MEWA) and KAUST have signed a strategic partnership agreement focused on research, development, and innovation. As part of this, MEWA is sponsoring Phase II of the Algae & Aquaculture Technologies Development Project at KAUST. The project aims to establish an algae industry in Saudi Arabia, create jobs, and reduce carbon dioxide emissions. Why it matters: This partnership signals a commitment to developing sustainable technologies and diversifying the Saudi economy through aquaculture and algal biotechnology.
KAUST and the National Center for Wildlife (NCW) are collaborating on research to protect Saudi Arabia's coastal ecosystems and marine economy from invasive species. They are conducting biodiversity surveys along the Red Sea and Arabian Gulf coasts, having surveyed 34 sites and collected over 10,000 samples. So far, 200 species with potential marine invasive traits have been identified, expanding the national knowledge base of marine life. Why it matters: The partnership aims to develop early detection and monitoring systems, fortifying Saudi Arabia's marine biosecurity efforts and supporting its Vision 2030 blue economy goals.
KAUST has launched a pilot algae facility as part of the DAB-KSA project, in collaboration with the Ministry of Environment, Water and Agriculture (MEWA). The facility aims to produce high-protein algae for animal feed, particularly for fish and poultry, using outdoor ponds and closed tubes. KAUST is positioning itself as a center for algal research, leveraging the Kingdom's resources like sunlight, saltwater, and CO2. Why it matters: This initiative could significantly reduce Saudi Arabia's reliance on imported animal feed and contribute to food security.
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.
