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.
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.
