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.
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 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.
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.
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.
MBZUAI is developing AI technologies to improve understanding and conservation of marine environments. AI algorithms analyze data from satellite imagery, ROVs, and sensors to identify patterns and trends, with machine learning models predicting oceanographic phenomena. Computer vision automates the identification of marine organisms, aiding in biodiversity assessments and ecosystem health evaluations. Why it matters: This research supports sustainability goals, such as improving biodiversity assessments and enabling faster responses to environmental events in the region's sensitive marine ecosystems.
An international team including KAUST researchers tracked nearly 2,000 sharks using satellite tags to map their movement and space use. The study found that 24% of shark habitats overlap with pelagic longline fisheries, with higher overlap for commercially exploited species. For North Atlantic blue and shortfin mako sharks, the overlap was 76% and 62% respectively. Why it matters: This research highlights the vulnerability of sharks to industrial fishing and underscores the need for targeted conservation efforts in critical habitats.
