A KAUST-led study published in Science found overwhelming evidence that man-made noise negatively impacts marine fauna and their ecosystems, disrupting behavior, physiology, and reproduction. The researchers assessed over 10,000 papers to demonstrate that noise pollution from shipping, fishing, and infrastructure development harms marine life from invertebrates to whales. They call for human-induced noise to be considered a prevalent stressor at the global scale and for policy to be developed to mitigate its effects. Why it matters: This research highlights the need to consider acoustic dimensions in ocean health restoration efforts, promoting management actions to reduce noise levels and allow marine animals to re-establish their use of ocean sound.
KAUST alumna Dr. Royale Hardenstine (Ph.D. '20, MS '15) is studying the movements and behavior of marine animals in the Red Sea, including whale sharks. Her Ph.D. research showed the connectivity of Red Sea whale sharks to the larger Indo-Pacific population and movements between aggregation sites. Now working as Protected Species Science Manager at The Red Sea Development Company, she monitors marine life in the Kingdom's future Special Economic Zones. Why it matters: This research is crucial for informing conservation efforts and mitigating the impact of coastal development on vulnerable marine species in the Red Sea.
A KAUST-led meta-study published in Science examines the increasing ocean noise pollution from human activities like shipping and seismic blasting. The study synthesizes findings from 10,000 papers, revealing that anthropogenic noise interferes with marine animals' communication and ecological processes. The research highlights the need for policymakers to address this issue for ocean health and sustainable economies. Why it matters: Understanding and mitigating ocean noise pollution is crucial for preserving marine ecosystems and the biodiversity of the Red Sea.
Researchers from KAUST and the University of Padova studied how hyperoxia, or excessive oxygen supply, extends heat tolerance in marine ectotherms. The study, published in Science Advances, examined the role of photosynthetic organisms like seagrasses in producing oxygen in aquatic habitats. They found that increased oxygen availability helps coastal marine animals like crabs, sea cucumbers, and shellfish increase their resilience to rising temperatures. Why it matters: Understanding the interplay between oxygen levels and temperature tolerance can inform strategies for preserving marine ecosystems in the face of global warming.
KAUST researchers developed a hybrid wireless communication system for non-invasive monitoring of marine animals, consisting of a lightweight, flexible, Bluetooth-enabled tag that stores sensor data underwater. The tag syncs data to floating receivers when the animal surfaces, which then relays the data via GSM or drones. The system is a collaboration between the Red Sea Research Center and KAUST's electrical engineering department. Why it matters: This technology provides researchers with detailed, near real-time data about marine animals, overcoming the limitations of invasive and impractical traditional tagging methods.
KAUST is hosting the Marine Megafauna Movement Workshop (October 19-20) featuring international speakers showcasing research on marine animal behavior using sensors and analytics. Enrichment in the Fall 2015 (October 16-24) at KAUST will focus on marine animal movement with lectures, trips, movies, and music. KAUST aims to merge research on marine animal movement with the study of human mobility to gain new insights. Why it matters: This interdisciplinary approach could advance understanding of both marine ecosystems and human behavior, while promoting marine conservation efforts in the Red Sea.
