KAUST researchers are using autonomous gliders in the Red Sea to monitor variables such as temperature, salinity, and chlorophyll, providing continuous, detailed measurements of the sea's physical and biogeochemical processes. These gliders can measure a number of variables, including temperature, salinity, chlorophyll, and concentration of dissolved organic matter. One glider was deployed for three months and monitored the formation of mesoscale eddies and anthropogenic inputs from aquaculture. Why it matters: This technology allows for a more comprehensive understanding of the Red Sea ecosystem and its dynamics, benefiting research and applications such as monitoring the impact of aquaculture, with potential implications for environmental management and sustainable resource utilization.
KAUST researchers studied microplastic distribution in the open ocean during a recent expedition. They found microplastics everywhere but in 100 times lower quantities than expected based on production estimates. The study found larger plastic debris at expected levels, but smaller microplastics were disappearing, suggesting they are either sinking or entering the marine food chain. Why it matters: This research highlights the urgent need to understand the fate of microplastics in marine ecosystems and their potential impact on marine life and human health.
KAUST hosted the International Conference on the Marine Environment of the Red Sea (ICMERS) from November 14-16. The conference brought together oceanography experts from KAUST and other international universities. Discussions focused on the state of Red Sea research, aiming to share knowledge, encourage new thinking, and develop a regional research map. Why it matters: The conference fostered collaboration and knowledge sharing to advance marine research and conservation efforts in the Red Sea region.
A collaborative research team including KAUST scientists has located a major sink for missing ocean plastic in coastal sediments and mangrove forests of the Red Sea and Arabian Gulf. Core samples showed a pattern of plastic sedimentation aligning with the history of global plastic production since the 1950s. Mangroves efficiently lock up microplastics in coastal soil, with plastic burial rates increasing similarly to global production. Why it matters: The findings highlight the critical role of mangroves in trapping plastic pollution and provide evidence that plastic sedimentation marks the start of a new geological epoch, the Anthropocene.
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.
A KAUST-led research team used acoustic readings to reassess fish populations in the ocean's mesopelagic zone (200-1000m depth). Published in Nature Communications, their findings indicate that mesopelagic fish quantities may be ten times greater than current estimates. The study also suggests that open-ocean ecosystems are as efficient as coastal regions in nutrient cycling. Why it matters: This discovery assigns mesopelagic fish a potentially significant, previously unrecognized role in the global carbon cycle and highlights KAUST's contribution to marine science.
Cindy Lee Van Dover, a professor at Duke University, spoke at KAUST's Winter Enrichment Program in 2017 about the blue economy. The blue economy refers to the sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystems. Why it matters: This highlights KAUST's interest in marine science and sustainable development related to ocean resources.
