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.
A KAUST-led international team has published research detailing the potential of marine-based solutions to combat climate change. The study assesses the effectiveness of 13 ocean-based measures, including reducing greenhouse gas concentrations and protecting marine ecosystems. The research will inform decision-makers at COP24. Why it matters: Highlighting the potential of ocean-based solutions can broaden the scope of climate action strategies in the region, where coastal environments and marine resources are vital.
A KAUST-led team used acoustic technology and net sampling to explore ocean depths in 146 locations worldwide. They found that the biomass of pelagic organisms in the deep sea is much larger than previously thought, especially below productive waters. Deep-sea fauna migrates to shallower areas to feed, transporting carbon to the deep sea. Why it matters: This suggests the ocean's carbon pump is more effective than previously understood, with implications for climate change mitigation strategies.
Three KAUST students attended the 5th International Marine Conservation Congress in Malaysia, which brought together over 650 attendees. The conference focused on translating marine conservation science into real action, with participants discussing topics like the impact of above-water marine species and sustainable fishing practices. KAUST students presented their work and shared insights from the event. Why it matters: This participation highlights KAUST's commitment to addressing critical ocean conservation challenges and fostering international collaboration in marine science.
KAUST researchers studied microplastic distribution in the open ocean during a recent expedition. They found microplastics everywhere but in 100 times lower quantities than expected based on production estimates. The study found larger plastic debris at expected levels, but smaller microplastics were disappearing, suggesting they are either sinking or entering the marine food chain. Why it matters: This research highlights the urgent need to understand the fate of microplastics in marine ecosystems and their potential impact on marine life and human health.
Dr. Luiz Rocha from the California Academy of Sciences discussed the impact of climate change on coral reefs during a keynote lecture at KAUST. He highlighted the phenomenon of coral bleaching due to rising water temperatures and its devastating effects on marine ecosystems. Rocha also spoke about exploring mesophotic coral ecosystems (MCEs), or the "twilight zone," at depths of 60-150 meters. Why it matters: Understanding the impact of climate change on coral reefs and exploring deeper marine ecosystems is crucial for preserving marine biodiversity in the face of global warming.
KAUST Discovery Professor Aranda's team has been researching coral adaptation to temperature and ocean acidification. The research is focused on the transgenerational aspect of this adaptation using controlled environments. The research has been ongoing for the past two years. Why it matters: Understanding the epigenetic mechanisms of climate resilience in corals is crucial for conservation efforts in the Red Sea and beyond.
KAUST researchers found a 25-30% increase in winter rainfall in the eastern Arabian Peninsula since 1981, with a 10-20% decrease in the south and northeast. This change correlates with a shifting El Niño pattern in the tropical Pacific Ocean, affecting sea surface temperatures and westerly winds. The study used rainfall data from the University of East Anglia and 39 stations across the peninsula from 1951-2010. Why it matters: Improved understanding of these climate drivers could enhance long-term rainfall predictions, benefiting agriculture and water resource management in this arid region.
