University of Washington scientists are pioneering an innovative approach to save endangered orcas by transforming America’s existing fiber-optic cable infrastructure into a massive underwater surveillance network.
This could potentially revolutionize marine conservation while leveraging technology we’ve already paid for.
Story Highlights
- Scientists deploy over a mile of fiber-optic cable in the Salish Sea to monitor endangered orcas using existing telecommunications infrastructure.
- Distributed Acoustic Sensing technology converts cables into continuous underwater microphones, providing unprecedented marine mammal tracking capabilities.
- The project could scale globally using 1.7 million kilometers of existing submarine cables, creating a cost-effective conservation network.
- Innovation addresses critical data gaps needed for High Seas Treaty implementation and marine protected area management.
Repurposing Infrastructure for Wildlife Protection
University of Washington researchers deployed over a mile of fiber-optic cable off San Juan Island in October 2025, testing whether Distributed Acoustic Sensing technology can continuously monitor orca vocalizations.
Professor Shima Abadi leads the team investigating how existing telecommunications infrastructure can serve dual purposes for conservation science.
The approach represents smart government efficiency by leveraging existing technology instead of creating expensive new monitoring systems from scratch.

Addressing Critical Conservation Data Gaps
Yuta Masuda from Allen Family Philanthropies, the project’s primary funder, emphasizes that wildlife management faces fundamental data shortages, which hamper effective conservation efforts.
Traditional hydrophone monitoring provides limited, spotty coverage compared to the comprehensive network possible with repurposed cable infrastructure. The timing aligns strategically with the High Seas Treaty, which takes effect in January 2026 and requires robust marine biodiversity data to establish new protected areas effectively.
Current orca populations face mounting pressures from ship traffic noise, salmon scarcity, and climate change impacts, yet conservationists lack real-time data on migration patterns and behavioral responses to these stressors.
The project addresses this gap by potentially creating continuous monitoring coverage across critical habitats. Enhanced data collection could inform evidence-based policies protecting marine mammals while supporting legitimate maritime commerce and fishing industries.
Scaling Innovation Through Existing Networks
The global submarine cable network spans over 1.7 million kilometers, carrying 99% of intercontinental internet traffic and representing decades of infrastructure investment.
Converting this existing network into acoustic sensors could create the world’s largest marine monitoring system without massive new government spending. The approach demonstrates fiscal responsibility by maximizing returns on previous telecommunications investments while advancing conservation goals.
Regulatory frameworks already exist for cable installation and maintenance, though balancing telecommunications needs with environmental protection requires careful coordination between federal agencies, state regulators, and industry partners.
The International Cable Protection Committee collaborates on assessing environmental impacts and opportunities, indicating industry willingness to support dual-use applications that benefit marine conservation without compromising communications infrastructure.
