Victor Vescovo and the Caladan Oceanic crew, in cooperation with KAUST, made multiple manned dives into the Red Sea. They reached the deepest point, the Suakin Trough, for the first time. The team also dove the Kebrit Deep, which is shallower but scientifically important. Why it matters: This exploration provides an opportunity to study and protect the unique resources of the Red Sea's deepest regions, furthering scientific understanding of these previously inaccessible environments.
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 the National Center for Wildlife (NCW) discovered an unexpected ecosystem deep below the Farasan Bank coral reef system in the Red Sea. The deep waters were inhabited by corals, fish, and other animals thriving in low oxygen and high acidity conditions. Creatures showed coping strategies like slower swimming and healthy coral growth despite conditions normally preventing calcification. Why it matters: The discovery highlights the Red Sea's significance as a natural laboratory for studying marine resilience to climate change, expanding our understanding of how marine life adapts to extreme conditions.
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.
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.
KAUST researchers have conducted the first measurements of deep-sea corals in the Red Sea. They retrieved specimens of three different species at depths of 300-750 meters and temperatures exceeding 20 degrees Celsius. This discovery challenges the existing understanding that deep-sea corals are exclusive to cold-water environments. Why it matters: The research expands known ecosystem boundaries for deep-sea corals and demonstrates their resilience in warm, nutrient-poor waters, offering new insights into marine biodiversity and adaptation.
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.
