One Site.
Watched Forever.
SYSENSE is a cabled, seabed-mounted observatory that streams acoustic noise and water-quality data in real time — continuously, indefinitely, with no batteries to swap. One permanent installation, accessed from anywhere via the internet, for ports, harbours, marine protected areas and construction sites.
When a recording isn't enough — you need the live feed
Battery recorders and surface buoys answer a campaign. A permanent monitoring obligation — a multi-year harbour development, a marine protected area, a port noise programme — needs something that simply never stops. SYSENSE is a seabed-mounted station tethered to a surface control point by cable, giving it unlimited power and a continuous, real-time link to both its acoustic array and its environmental sensors.
- Cable-powered — runs indefinitely, no battery swaps or recovery dives
- Acoustic hydrophone array and a water-quality sensor suite in one install
- All data accessible remotely over the internet — no site visit to see it
When fixed, continuous and remote is the only answer
SYSENSE is the right tool when the monitoring can't pause, the data must be live, and acoustics and water quality have to be measured together.
🔁 No Gaps Allowed
Permitted programmes can't tolerate the blind windows between recorder deployments. A cabled station has none.
🌐 Decisions Off-Site
Managers and regulators need to see conditions from their desk. Remote internet access removes the site visit.
🔗 Correlated Signals
A noise event means more when tied to turbidity, salinity and temperature at the same instant — one station does both.
📋 Audit Burden
Permit reporting eats analyst time. Automated report generation turns continuous data into defensible records.
SYSENSE — continuous real-time seabed monitoring
A hydrophone acoustic array and a multiparameter sensor suite on one seabed frame, cabled to the surface for unlimited power and an unbroken data link.
Two monitoring jobs, one cabled installation
SYSENSE combines a hydrophone array with full PAM capability and a comprehensive water-quality sensor suite, all on a fixed seabed station. Power and data run over a tethered cable to a surface control point, so unlike battery recorders or surface buoys it operates indefinitely — ideal for permanent coastal installations where data continuity and remote access are essential. Versatile software handles remote control, data access and automated report generation.

Acoustics and environment, correlated in real time
SYSENSE's value is in the combined picture — a noise event read against the water conditions at the same moment, all available live and remotely.
Detect the soundscape, characterise the habitat
The acoustic array supports passive acoustic monitoring, marine-mammal detection and ship-noise characterisation, while the sensor suite tracks the water around it. Together they enable ecosystem work that neither could do alone — including fish-vocalisation detection for habitat assessment, such as monitoring Posidonia meadow health through fish sound, benthic soundscape mapping and crustacean behaviour studies.
- Correlate noise events with turbidity, salinity and temperature
- Fish & invertebrate vocalisation detection for habitat health
- Automated compliance reports for permits and publications
One station, the complete environmental picture
SYSENSE combines underwater acoustic monitoring with a full water-quality and oceanographic sensor suite — no separate acoustic and environmental deployments.
Where the SYSENSE observatory excels
Permanent and semi-permanent inshore installations where continuous data, real-time remote access and multi-parameter monitoring are essential.
Harbour & Port Construction
Continuous acoustic and turbidity monitoring through dredging, quay-wall construction and port expansion, with automated permit reporting.
Marine Biology & Ecology
Long-term acoustic ecology — fish characterisation, mammal presence, Posidonia habitat assessment and seasonal soundscapes.
Maritime Shipping Noise
Permanent URN stations in port approaches and shipping lanes for continuous vessel-noise characterisation programmes.
Marine Renewable Energy
Fixed acoustic and environmental monitoring at tidal-turbine and cable-landfall sites, correlating noise with sediment and current.
Oceanographic Research
Long-term coastal observatory stations delivering continuous multiparameter datasets for climate and impact studies.
Regulatory Compliance
Meeting EU Habitats Directive, MSFD and EIA requirements with continuous, auditable, automated monitoring records.
