Aquaculture & Industrial Water Monitoring
Real-time water quality for marine aquaculture and industrial water, from the netH₂O B770 buoy — with AI-ready data.
The netH₂O B770 is a modular, cloud-connected monitoring buoy — built for harsh marine conditions, simple to deploy, and low-maintenance. It hosts up to four TriOS water-quality sensors and streams data to the cloud, integrating into daily operations for fish farming, shellfish cultivation, industrial water management, and environmental monitoring.
A rugged HDPE shell and a 60 Ah / 768 Wh battery let the B770 run unattended for long deployments, on a single mooring or fixed to an existing structure such as a fish-cage ring.
Fish Farming & Aquaculture
Bring real-time monitoring to marine aquaculture, with data that bears directly on stock health and product quality.
Measured by the application packs:
- Dissolved Oxygen – TriOS eCHEM optical sensor; optimise stock health and feeding
- Conductivity / Salinity – TriOS eCHEM inductive sensor; detect freshwater intrusion
- Chlorophyll-a – TriOS nanoFlu fluorometer; track phytoplankton and algal blooms
- Turbidity – TriOS TTurb nephelometric sensor; monitor suspended solids
- Temperature & wave/current estimation – included in the base platform
Data flows to operators for optimised feeding schedules, proactive oxygenation management, and early detection of freshwater contamination — protecting your stock before problems escalate.
Mussels & Shellfish Farming
Shellfish cultivation demands precise environmental control. The B770 provides the data foundation for maintaining optimal growing conditions and ensuring premium product quality.
Monitor the dynamic saltwater-freshwater boundary as it shifts with rainfall, tidal cycles, wind patterns, and wave action — real-time intelligence that is essential for:
- Maintaining optimal salinity ranges for growth
- Preventing contamination from freshwater runoff
- Timing harvest operations
- Ensuring product quality and safety
Deploy at farm sites or near river mouths to build comprehensive monitoring networks that protect your harvest.
Desalination Plants
Balance environmental stewardship with operational efficiency. The B770 enables precise monitoring of brine plume dispersion, so operators can make data-driven decisions.
Operational benefits:
- Real-time tracking of brine plume location and concentration
- Reduce discharge flow during environmentally sensitive conditions
- Maximise production when conditions permit
- Demonstrate regulatory compliance with documented data
- Optimise daily operations for both environmental and economic performance
Smart brine management protects marine ecosystems while maximising plant efficiency.
Power Plants & Thermal Discharge
Coastal power-generation facilities using seawater cooling must carefully manage thermal discharge to minimise ecological impact and maintain compliance.
Deploy B770 buoys at multiple monitoring points to:
- Track thermal plume dispersion patterns in real time
- Document compliance with environmental regulations
- Optimise cooling-water intake and discharge operations
- Limit potential ecological damage
- Provide comprehensive environmental reporting data
Multi-location temperature monitoring enables proactive environmental management.
River Outflows & Estuary Monitoring
Build monitoring networks at river mouths, canal outlets, and estuaries. Track the dynamic saltwater-freshwater boundary and its movement under the influence of:
- Seasonal rainfall and runoff patterns
- Wind-driven mixing and circulation
- Tidal cycles and tidal currents
- Wave action and storm events
AI-enhanced predictions: the data can feed netH₂O’s AI models to forecast boundary movements hours or days in advance — valuable for coastal tourism management, aquaculture, water-quality assessment, and environmental protection.

Why netH₂O?
Also Ideal for Periodic Remote-Site Inspection
The B770 suits agencies and companies that need periodic monitoring of remote or difficult-to-access locations.
Simplified workflow: the buoy arrives complete with sensors, data storage, and communications. Deploy at the site, let it acquire and transmit data automatically, and retrieve it when complete — enabling significant cost savings and more frequent monitoring.
