C2 OCEAN NOISE
REAL-TIME PASSIVE ACOUSTIC MONITORING FOR MARINE MAMMALS, VESSELS & CONSTRUCTION NOISE
BUOY
Smarter Marine Monitoring for Dynamic Soundscapes
The C2 Ocean Noise Module is a purpose-built, autonomous marine monitoring system designed as a portable module that can be fitted to existing buoys, as a handheld or cabled system or as complete acoustic buoys. Operating continuously in busy harbours, near shipping channels, and remote waters, the C2 Module delivers real-time acoustic detection and classification of marine mammals, construction noise and vessels.
Traditional ocean bioacoustics relies on passive hydrophones or recorders that require physical retrieval of submerged instruments, which means critical insights are delayed and not available for adaptive management of underwater noise. The C2 Module changes this by brining AI inference directly to the hydrophone. Cellular or satellite telemetry allows for detection data be sent as alerts to mobile phones or as packets with audio snippets to live dashboards or email.
Why Choose the C2 Module?
- Proven High-Precision AI: Powered by kiwi-built AI for ocean bioacoustics with demonstrated accuracies over 98% (0.98 recall, 0.99 precision rates) in real-world coastal deployments.
- Ecologically Meaningful Metrics: Run ecologically meaningful analyses at the edge, such as Listening Space Reduction (% LSR) for marine mammals that quantify how anthropogenic noise reduces the distance over which marine mammals can hear each other, or prey.
- Adaptive Noise Removal (ANR): Advanced signal processing automatically isolates target marine mammal vocalisations from high background noise such as from shipping, pile driving, dredging, etc.
- Real-Time Automated Alerts: Receive SMS messages or emails with spectrograms, audio snippets, or custom metrics specific for your project to your phone or email.
- Continuous 24/7 operation: Solar power provides continuous, 24/7 operation in challenging marine environments.
- Data transparency: Obtain verifiable acoustic datasets tailored for marine science research, environmental consent monitoring and marine mammal management plans.
Modular design for adding to existing buoys, running with your own hydrophone hardware, or as a complete buoy solution. Our complete buoy solution can provide recording capabilities at 16, 24 or 32 bit and up to 384 kHz sampling rates.
Beyond Simple Monitoring: Ecologically Meaningful Marine Metrics
Translating Underwater Sound into Acoustic Habitat Quality
Standard monitoring systems can transmit live detections of marine mammals or sound pressure levels but cannot run additional ecological analyses. The C2 Module can translate those raw acoustic data into actual ecological insights, such as tracking changes to a dolphin or whales acoustic habitat quality.
Flexible Edge AI: Put You in Control of Your Data Collection Methods
Several state-of-the art AI models and bioacoustics detectors/classifiers are widely used in the scientific community. This means that existing monitoring projects have established methods used for monitoring certain ecosystems. The C2 Module offers the ability to run different, or multiple AI models for comparable purposes, models such as Cetus4 (Cetaware’s own AI model), or open-source models such as Google’s SurfPerch. This means researchers can deploy their own methods at the edge.
Every ecosystem is unique, and monitoring priorities change over time. The C2 Module puts control in your hands.
- Simultaneous Multi-Model Pipeline: Run multiple deep-learning models concurrently to monitor vastly different spectral targets from a single hydrophone.
- Model retraining: Validate classifications to fine-tune models to improve performance, even after the system has been deployed.
- Seamless OTA Evolution: As AI evolves, over-the-air updates ensures you always have the latest technology available.
Benefits for Stakeholders
- Ecologists & Conservation Teams: Eliminate manual SD card retrieval and gain real-time, as well as historical, insights on habitat use by vocal species.
- Government Agencies & Councils: Build transparent and verifiable datasets on marine mammal activity that are available on live dashboards. Or, monitor compliance with underwater noise limits in real-time with exceedances being logged and emailed automatically.
- Port Companies: Understand local marine mammal activity to adaptively management port operations and protect marine mammals inside shipping channels.
- Consultants & Regulators: Survey habitats or obtain baseline data on species presence and habitat use to inform impact assessments.
- Researchers & Universities: Deploy AI models, or custom methods, used on existing projects, to the edge and automate your data collection, which equals more time to focus on what matters.
