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 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.
KAUST and GEOMAR Helmholtz Centre for Ocean Research Kiel collaborated on a research expedition in the Red Sea aboard the R/V Meteor in October. The first cruise (M193 REPLENISH) focused on the Al Wajh coral reefs, while the second (M194 HEXPLORES) aims to discover undiscovered black smoker hydrothermal vent fields. HEXPLORES is led by Dr. Nico Augustin from GEOMAR and Dr. Froukje van der Zwan from KAUST. Why it matters: This collaboration highlights KAUST's role in spearheading Red Sea studies and attracting global experts to the region, furthering our understanding of the Red Sea's unique ecosystem and geological features.
