Forth Road Bridge: Acoustic sensors monitor internal wire fractures as corrosion halts

Engineers have successfully slowed corrosion in the Forth Road Bridge’s main cables by pumping dry air through them, reducing internal humidity to below 40%. However, acoustic sensors continue to detect individual steel wire fractures, with 93 breaks logged by 2015 and a spike of 24 breaks in a single cable shortly after. While the bridge’s strength loss is estimated at 8-10%, the drying process has prevented further degradation, allowing the structure to remain open for non-motorized traffic.

Six-year Monterey Bay hydrophone reveals humpbacks rise, blue whales lag after marine heat wave

A single hydrophone 891 meters deep in Monterey Canyon collected six years of continuous whale-song data, showing humpback songs climbed from 34% to 76% of days while blue whale songs dipped during and after a marine heat wave—reflecting prey-driven, species-specific foraging responses and illustrating how long-term acoustic monitoring can serve as an ocean-health indicator.

Dzanga Bai: A Long-Term Window into Forest Elephant Life

Long-term work at Dzanga Bai blends direct elephant observation with 24/7 acoustic monitoring to map forest elephants’ social lives, track population trends, and detect threats, while training local researchers and partnering with nearby communities to build a sustainable, locally led conservation model; despite ongoing poaching risks and funding dependence, the site shows a relatively stable population and demonstrates how forest health, livelihoods, and elephant protection are deeply linked.

"Uncharted Territories: AI Reveals Monkeys' Avoidance Patterns through Enhanced Audio Monitoring"

Researchers from Imperial College London have used AI-enhanced audio monitoring to study the behavior of Geoffroy's spider monkeys in Costa Rica. The study found that the monkeys are not found in areas with less than 80% forest cover and within one kilometer of a paved main road. The research highlights the importance of identifying thresholds for threatened species and provides valuable information for conservation strategies. The use of passive acoustic monitoring, combined with AI technology, allowed the researchers to analyze 35,805 hours of audio in just eight weeks, significantly speeding up the study process. The findings emphasize the negative impact of forest loss and road construction on monkey habitats and underscore the need for targeted conservation efforts.
