KAUST researchers Carlos Preckler and Diego Rivera participated in Saudi Arabia's first scientific mission to Antarctica from January 11 to February 27. They collected ocean samples to study how whale populations mitigate climate change through carbon sequestration. The team aims to quantify the impact of whales on carbon capture and correlate whale population dynamics with carbon sequestration over the past 400 years. Why it matters: This research provides valuable insights into the economic benefits of whale conservation and contributes to global efforts in understanding the role of marine ecosystems in climate change mitigation.
KAUST researchers analyzed bacterial communities from Deception Island, Antarctica, finding heat-loving bacteria with potential for oil cleanup. Postdoctoral student Junia Schultz is now characterizing the microbiome of extreme terrestrial environments in Saudi Arabia, including volcanoes and deserts. These extremophiles secrete surfactants to break down oil and absorb it into their cells for degradation. Why it matters: This research could lead to efficient and safe methods for cleaning up oil contamination using extremophiles found in both Antarctica and Saudi Arabia.
A KAUST-led research team is deploying DNA sequencing technology originally used on the International Space Station to analyze DNA samples in extreme environments along the Saudi Red Sea coast. The portable technology enables on-site extraction, concentration, and sequencing of samples from coral reefs and mangrove forests, minimizing DNA deterioration. Preliminary results indicate a more diverse and complex microbiome than previously found. Why it matters: This application of space-based technology to marine conservation in the Red Sea could provide critical insights into how coral reefs and mangroves adapt to climate change, informing preservation and restoration efforts.
Three KAUST PhD students participated in OceanQuest's "Around Africa Expedition" aboard the RV OceanXplorer, focusing on deep-sea research and biodiversity assessments. The students gained hands-on training in marine equipment usage and sample collection across multiple seamounts in the Indian Ocean. One student collected volcanic rock samples to investigate the origins of seamount formations. Why it matters: This initiative strengthens KAUST’s engagement in marine science and aligns with Saudi Vision 2030 by developing next-generation talent in ocean research.
KAUST Professor Alexandre Rosado studies extremophiles in extreme environments, including Saudi deserts, volcanoes, hot springs, and mangroves. His team researches the diversity and biotechnological potential of microorganisms in these harsh Saudi ecosystems. The logistical challenges of collecting samples in remote and extreme conditions are significant. Why it matters: This research can reveal new species and processes with biotechnological applications, particularly in bioremediation and understanding life's limits.
