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.
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 researchers have made the first direct observations of active hydrothermal vent fields in the Red Sea, specifically on Hatiba Mons. The total active area spans 1.6 km2, the largest reported globally, with vent temperatures around 40 degrees Celsius supporting thriving microbial communities. The observations, confirmed using remotely operated underwater vehicles (ROVs), build on over a decade of data collection. Why it matters: These findings provide insights into the Red Sea's unique biological and mineralogical resources, offering a model to study the evolution of life in extreme environments.
A KAUST-led study has revealed a unique microbial ecosystem in the Hatiba Mons hydrothermal vent fields of the Red Sea, first documented in 2023. Using genome-resolved metagenomics, the study reconstructed over 300 microbial genomes from five vent sites. The analysis showed an ecosystem dominated by microbes capable of iron, sulfur, nitrogen, and carbon cycling, unlike most hydrothermal vents that are sulfur- and methane-based. Why it matters: The discovery provides new insights into microbial processes in extreme conditions, ocean resilience, and global carbon cycling, highlighting the interplay between geology and biology in the Red Sea.
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.
