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 have developed an AI system for the Saudi Geological Survey (SGS) to improve the scientific understanding of seismic activity in Saudi Arabia. The AI system helps the SGS analyze swarm earthquakes, which are common in volcanic regions and difficult to decipher using conventional methods. The system allows for a more reliable survey of seismic regions, better infrastructure planning, and improved building codes. Why it matters: The AI system enhances Saudi Arabia's ability to monitor and respond to seismic events, contributing to public safety and infrastructure resilience.
KAUST researchers have developed a detailed 3D dynamic model using data from the February 2023 Turkiye earthquake to improve earthquake simulations. The model incorporates 3D fault geometry and Earth structure for realistic simulations of ground shaking. It explains complex ground shaking patterns and the impact of supershear ruptures, which can amplify damage far from the epicenter. Why it matters: This research provides a more accurate understanding of earthquake rupture processes, crucial for seismic hazard assessment and infrastructure planning in seismically active regions like the Middle East.
KAUST and Cerebras Systems collaborated on multi-dimensional seismic processing using the Condor Galaxy AI supercomputer, achieving record sustained memory bandwidth of 92.58 petabytes per second. They developed a Tile Low-Rank Matrix-Vector Multiplication (TLR-MVM) kernel to exploit the architecture of Cerebras CS-2 systems. This work was recognized as a finalist for the 2023 Gordon Bell Prize. Why it matters: This demonstrates the potential of AI-customized architectures for seismic processing, with broader implications for climate modeling and other scientific domains in the region and globally.
KAUST researchers and German collaborators explored the Red Sea's depths using the RV Meteor, employing ROVs and seismic equipment to map geological and biological features. They examined underwater hot springs, microbial mats, and deep-sea brine pools, discovering hydrothermal vent fields with unique ecosystems. The research, involving multidisciplinary teams, provides insights into the Red Sea's geology, ecosystems, and biodiversity. Why it matters: Studying the Red Sea's unique environment can offer valuable knowledge about young ocean development and novel marine ecosystems, relevant for understanding similar geological formations and biodiversity hotspots in the region.
Geophysicists at KAUST are investigating the "doublet" earthquake phenomenon in Turkey, where two strong earthquakes of magnitude 7.8 and 7.7 occurred within nine hours of each other on separate faults. Researchers from the Crustal Deformation and InSAR Group and the Computational Earthquake Seismology research group are using satellite and seismic data to examine the earthquake rupture process. The National Center for Earthquake and Volcano monitoring (NCEV) of the Saudi Geological Survey contributes seismic recordings to the KAUST teams. Why it matters: Understanding such earthquake doublets is crucial for improving seismic hazard assessment and risk mitigation in the region and globally.
A KAUST-led meta-study published in Science examines the increasing ocean noise pollution from human activities like shipping and seismic blasting. The study synthesizes findings from 10,000 papers, revealing that anthropogenic noise interferes with marine animals' communication and ecological processes. The research highlights the need for policymakers to address this issue for ocean health and sustainable economies. Why it matters: Understanding and mitigating ocean noise pollution is crucial for preserving marine ecosystems and the biodiversity of the Red Sea.
KAUST Ph.D. graduate Tariq Alturkestani won the best paper award at Euro-Par 2020 for his doctoral thesis on overlapping I/O and compute in large-scale scientific computation using multilayered buffering mechanisms. His work re-evaluates the Reverse Time Migration (RTM) method used by geoscientists for oil and gas explorations, utilizing emerging storage technologies. The paper was co-authored with Professor David Keyes and Dr. Hatem Ltaief from the KAUST Extreme Computing Research Center (ECRC). Why it matters: This award highlights KAUST's growing prominence as a hub for Saudi talent and research in supercomputing and extreme computing, particularly in applications relevant to the region's energy sector.
