Underwater Sensor Suite That Monitors Ocean Health from 2000m Deep in Real Time

environmentPilotedTRL 7

Imagine dropping a Swiss Army knife of sensors into the ocean that can detect everything from DNA traces of fish species to microplastics and toxic algae — all while sitting on the seafloor over 2 kilometres down. That's what TechOceanS built: 9 miniaturised technologies packed into underwater vehicles that measure pollution, track marine life, and monitor water chemistry without needing to haul samples back to a lab. Think of it as a portable medical lab for the ocean, running blood tests on seawater in real time. The team tested these tools at real ocean sites near Naples and the Canary Islands, proving they work outside the laboratory.

The business problem

What needed solving

Ocean industries — aquaculture, offshore energy, environmental consultancies — spend millions on ship-based sampling campaigns and lab analysis to monitor water quality, detect pollution, and comply with marine regulations. Current methods are slow, expensive, and give you snapshots instead of continuous data. Companies need real-time, in-water sensing that works autonomously at depth without sending out research vessels.

The solution

What was built

The project built 9 operational ocean sensing technologies: 5 miniaturised sensors (DNA/RNA analyser, nutrient and carbonate lab-on-chip, contaminant and toxin detector, productivity sensor, and a micro-cytometer for microplastics), 2 imaging systems, 1 particle sampler collecting up to 1000 samples, and an AI image processing system for data compression. All systems are submersible to over 2000 metres with a platform-independent data acquisition module.

Business applications

Who can put this to work

Aquaculture & Fish Farming

mid-size

Target: Offshore aquaculture operators and fish farm companies

If you are an aquaculture operator dealing with sudden fish kills from harmful algal blooms or undetected parasites — this project developed lab-on-chip sensors and a micro-cytometer that detect biotoxins, pathogens, and parasites directly in the water column. These sensors were demonstrated at real ocean sites and can be deployed on underwater vehicles, giving you early warnings before contamination reaches your stock. The system covers 12 out of 19 priority ocean variables relevant to water quality.

Environmental Monitoring & Compliance

any

Target: Marine environmental consultancies and regulatory agencies

If you are an environmental consultancy tasked with monitoring pollution under the Marine Strategy Framework Directive — this project built sensors that detect organic contaminants, microplastics, and biotoxins at depths exceeding 2000 metres. The technologies measure 39 out of 73 essential ocean sub-variables, dramatically reducing the need for expensive ship-based sampling campaigns. Proof-of-concept demonstrations were completed at two sites in Naples and the Canary Islands.

Offshore Energy & Subsea Industries

enterprise

Target: Offshore oil & gas operators and wind farm developers

If you are an offshore energy company required to monitor environmental impact around your installations — this project created submersible DNA and chemical sensors that operate autonomously on underwater vehicles below 2000 metres. Instead of sending divers or retrieving sampling bottles, you get real-time data on species presence, pollutants, and water chemistry. The 14-partner consortium included 4 industry partners who helped design these tools for operational conditions.

Frequently asked

Quick answers

What would these sensor systems cost compared to traditional ocean monitoring?

The project does not publish specific pricing. However, lab-on-chip and miniaturised sensor technology is designed to replace expensive ship-based sampling campaigns and shore-based laboratory analysis. Based on available project data, operational cost savings come from autonomous deployment on underwater vehicles rather than crewed research vessels.

Can these sensors work at industrial scale across large ocean areas?

Yes — the sensors are designed for deployment on multiple underwater vehicles simultaneously. The project demonstrated technologies at two distinct ocean sites (Naples and Canary Islands), and the systems collectively measure 12 out of 19 priority biogeochemical and ecosystem ocean variables. The platform-independent data acquisition module ensures interoperability across different vehicle types.

Who owns the intellectual property and can I license these technologies?

IP is held by the 14-partner consortium across 8 countries, which includes 4 industry partners and 3 SMEs. The project objective explicitly states that TechOceanS expects to commercialise the technologies resulting from this project. Licensing enquiries should be directed to the coordinator, National Oceanography Centre (UK).

Do these sensors meet regulatory requirements for marine monitoring?

The project specifically targets variables required under the Marine Strategy Framework Directive (MSFD), including measurements of litter, plastics, biotoxins, parasites, pathogens, and organic pollutants. The sensors cover at least 63% of priority Essential Ocean Variables, making them directly relevant for EU regulatory compliance reporting.

How mature are these technologies — are they ready to buy?

The project ran from 2020 to 2024 as an Innovation Action, which targets near-market technologies. Deliverables confirm operational prototypes of lab-on-chip sensors, a genomic sampler, and a micro-cytometer, with proof-of-concept demonstrations completed at two ocean sites. User and engineer manuals were produced, indicating readiness for early adopter deployment.

Can I integrate these sensors with my existing ocean monitoring infrastructure?

Yes — the project developed a platform-independent and interoperable data acquisition module specifically for this purpose. The sensors were demonstrated on multiple underwater vehicles, and the AI-based image processing enables data compression and transmission from remote ocean locations, reducing bandwidth requirements.

Consortium

Who built it

The TechOceanS consortium brings together 14 partners from 8 countries, with a healthy mix of 6 research organisations, 4 industry players, and 3 universities. The 29% industry ratio and 3 SME participants signal genuine commercial intent — these are not just academic exercises. The coordinator is the National Oceanography Centre in the UK, one of Europe's leading marine science institutions with strong links to industry. The geographic spread across Cyprus, Germany, Greece, Spain, France, Ireland, Italy, and the UK covers major European maritime economies, which matters for regulatory alignment and market access across the EU and UK.
