Turning Existing Undersea Internet Cables into Giant Environmental and Seismic Sensors

environmentTestedTRL 5

Imagine the internet cables on the ocean floor acting like a giant nervous system for the planet. Instead of just carrying data, these cables can feel vibrations and changes in light to detect earthquakes or ocean currents. This project turns standard telecom lines into a massive, permanent sensing network without needing to lay new cables.

The business problem

What needed solving

Deploying dedicated undersea sensors is prohibitively expensive and difficult to maintain. Current monitoring is often fragmented into isolated experiments with restricted data access.

The solution

What was built

A standardized architecture and instruments that turn live telecom fibers into sensors using DAS and SoP technologies. This includes a data pipeline integrated with European data platforms.

Who can put this to work

Telecommunications
enterprise
Target: Submarine cable operators

If you are a cable operator dealing with high costs of dedicated monitoring hardware — this project developed a way to use existing live telecom fibers for sensing. This allows you to offer new data services to governments and researchers using the same infrastructure. It reduces the need for expensive dedicated submarine fibers.

Civil Protection
any
Target: Government disaster management agencies

If you are a public body dealing with slow tsunami or earthquake alerts — this project developed a standardized system for continuous ocean-bottom monitoring. This provides high-quality data for early warning systems. It leverages a network across 15 countries to improve safety.

Maritime Engineering
mid-size
Target: Submarine cable designers

If you are a cable manufacturer dealing with imprecise sensor calibration — this project developed new methods for industrial sensor calibration. This leads to better submarine cable designs. It uses real-world data from three geographically diverse locations.

Frequently asked

Quick answers

How does this reduce deployment costs?

The project demonstrates cost-efficient use of existing telecommunications infrastructure instead of laying dedicated submarine fibers. This removes the need for expensive new cable deployments for research purposes.

Can this be scaled across different regions?

Yes, the project is installing standardized instruments in at least three geographically diverse locations. It involves partners from 15 countries across Europe and the Americas.

Who owns the IP and how is data licensed?

Based on available project data, the project follows open science principles and generates large-scale datasets accessible through European platforms like EOSC and Copernicus.

How does this integrate with existing systems?

The system integrates with NREN and EPOS infrastructures and the Copernicus Marine service. It uses a unified architecture to combine DAS and SoP techniques into a single system.

What is the timeline for the results?

The project period runs from 2023-05-01 to 2026-04-30.

Consortium

Who built it

The consortium is heavily weighted toward research (13 partners) and universities (6 partners), but includes 4 industrial partners and 3 SMEs. With a 13% industry ratio, the project is primarily research-driven but has enough commercial presence to ensure the developed tools are compatible with real-world telecom infrastructure across 15 countries.
