CSignum transforms the transmission of critical environmental data across the air-water boundary and through fresh and salt-water to monitor pollution and environmental changes in the world’s oceans, lakes and rivers, without disrupting the aquatic ecosystem.


CSignum enables precision aquaculture for offshore fish farming, providing farmers a way to automate and process data across multiple fish pens and increase the reliability, efficiency, safety, and sustainability of fish production.

Subsea Structures

Offshore wind farm and oil and gas operators now have a wireless solution that monitors fatigue, corrosion, strain, pressure, temperature and currents in turbid, choppy, ambient light and biofouled environments.

Security & Defence

CSignum technology is valuable for governmental security and defence initiatives providing essential connectivity for the secure, successful transmission of critical data through solid and liquid mediums – fully enabling the monitoring of deployed underwater or underground sensors.
