KAUST researchers have found conclusive evidence that the Red Sea completely dried out approximately 6.2 million years ago. Using seismic imaging, microfossil evidence, and geochemical dating, they determined a massive flood from the Indian Ocean refilled it in about 100,000 years. The flood carved a 320-kilometer-long submarine canyon and restored marine conditions. Why it matters: This discovery provides insights into extreme environmental events and the Red Sea's unique geological history, distinguishing it from the refilling of the Mediterranean.
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.
KAUST's Coastal and Marine Resources (CMR) Core Lab has been accredited by the International Organization for Standardization (ISO) to ISO/IEC 17025. The accreditation confirms the lab's competence in performing calibrations with global quality standards. KAUST is the first university in the Kingdom and the GCC region to receive such recognition for oceanographic instrument calibration. Why it matters: This certification enhances the reliability of research data and positions KAUST as a leader in marine research infrastructure within the region.
A KAUST-led study analyzing over 100 years of satellite data indicates that Red Sea surface temperatures may be cooling rather than rising due to the Atlantic Multidecadal Oscillation (AMO). The research, utilizing KAUST's supercomputer Shaheen II, suggests a cooling phase in the coming decades that could temporarily counter global warming effects. The team collaborated with researchers from the University of Athens and the Hellenic Centre for Marine Research, using data from NOAA, NASA, and the UK Met Office. Why it matters: The finding challenges assumptions about uniform warming trends and highlights the role of natural climate oscillations in modulating regional temperature changes, informing more accurate climate modeling and adaptation strategies for the region.
A collaborative research team from KAUST and King Abdulaziz University (KAU) conducted a 16-day study of the Red Sea aboard the KAU research vessel RV Al-Azizi. The study measured a pelagic transect of the Red Sea, examining nutrient cycling, ecosystem health, and biodiversity. The research was part of a Saudi Arabian contribution to the Second International Indian Ocean Expedition (IIOE-2). Why it matters: This collaboration demonstrates resource sharing between Saudi universities, contributing to Saudi Vision 2030 goals and furthering understanding of the Red Sea's ecosystem.
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.
KAUST researchers, in collaboration with WHOI, studied whale shark movement patterns near the Shib Habil reef in the Red Sea over six years using visual census, acoustic monitoring, and satellite telemetry. The study monitored 84 sharks and found the aggregation to be highly seasonal, with sharks most abundant in April and May, returning yearly. The site may serve as a nursery for the wider Indian Ocean population, attracting juvenile females, which is unique to Shib Habil. Why it matters: Understanding whale shark behavior and critical habitats like Shib Habil is vital for future conservation efforts of this endangered species in the Red Sea and the broader Indian Ocean.
