This week marked a significant milestone for atdepth as our monitoring team, led by Souha, successfully deployed our Standard Monitoring Unit (SMU) in Lake Champlain. This deployment represents a crucial step forward in our mission to operationalize ocean intelligence through next-generation Ocean Digital Twins.

What is the Standard Monitoring Unit?

The SMU sits at the core of our purpose-driven monitoring solution, designed specifically to serve our Ocean Digital Twin system. Unlike traditional monitoring approaches that collect data in isolation, the SMU is engineered to minimize uncertainty and enable real-time validation of digital twin outputs.

SMU Technical Specifications

Carbon Chemistry
pH, pCO₂ sensors for CO₂ removal verification
Physical Oceanography
Temperature, salinity, density profiling
Hydrodynamics
Current speed/direction measurement
Environmental
Turbidity monitoring for biogeochemical validation
Data Architecture
Integrated telemetry with Sofar Smart Mooring
Communication
Bristlemouth DevKit for real-time data transmission

Bridging Physical and Digital

The SMU transforms traditional monitoring from reactive data collection to proactive model validation. By integrating directly with our Ocean Digital Twin system, it enables continuous verification of simulation outputs against real-world conditions.

Lake Champlain: The Perfect Testing Ground

Lake Champlain provides an ideal environment for testing our monitoring systems before ocean deployments. The controlled freshwater conditions allow us to validate sensor performance, data transmission protocols, and integration workflows without the complexities of marine environments.

This deployment allowed our team to test critical operational procedures including sensor calibration, data quality assurance, and real-time telemetry systems that will be essential for upcoming marine carbon removal monitoring projects.

From Testing to Operations

The successful Lake Champlain deployment is part of our broader strategy to independently assess marine carbon dioxide removal operations. Our monitoring systems are being designed to provide the rigorous measurement, reporting, and verification (MRV) capabilities that the scaling mCDR industry requires.

Building the Future of Ocean Intelligence

This deployment represents more than just testing equipment—it’s validating our vision of operationalized ocean intelligence. By combining high-resolution monitoring with advanced Ocean Digital Twins, we’re creating the infrastructure needed for next-generation marine operations.

More deployments are scheduled over the coming weeks as we continue building the foundation for reliable, scalable ocean monitoring that can support everything from marine carbon removal verification to offshore renewable energy optimization.

What's Next?

The Lake Champlain deployment marks the beginning of an intensive testing phase. Over the coming months, we'll be deploying SMUs in increasingly complex marine environments, working toward our goal of providing gold-standard MRV for the marine carbon removal industry.
