The Monitoring Gap

Ocean monitoring has historically been constrained by the repeating problems of cost and coverage. Satellite observation provides surface-level data across large areas but cannot penetrate the water column. Research vessels provide detailed data at significant cost and limited geographic reach. Fixed sensor arrays provide continuous data but only at fixed points. This all adds up to a monitoring infrastructure that is fragmentary, capturing decent snapshots, but poor at the comprehensive picture that effective conservation and security need.

Autonomous systems are beginning to close that gap in ways that fixed and crewed infrastructure cannot. Uncrewed surface vessels operating continuously across ocean monitoring zones can collect environmental, meteorological and maritime traffic data at an economy of scale that crewed vessels can’t reach and without the operational constraints of human endurance. Autonomous underwater vehicles can survey the ocean floor, inspect port and pipeline infrastructure, and detect subsurface threats in environments and depths that would require prohibitively expensive crewed operations to access.

This is where the fourth Blue Action Canada Cohort is operating. Three ventures, Whale Seeker, ACUA Ocean and Deepwater Robotics are building complementary layers of the ocean intelligence infrastructure, each addressing a different dimension of the monitoring gap.

Full-Ocean Monitoring from the Surface with ACUA Ocean 

A returning cohort member, ACUA Ocean's autonomous uncrewed surface vessels are designed for full-ocean monitoring and data collection protecting seas and oceans from threats that range from illegal fishing and pollution to maritime security and environmental degradation. Operating continuously without a crew, the vessels collect data across environmental, navigational and security domains simultaneously, creating the kind of persistent ocean picture that episodic crewed missions cannot deliver.

The dual-use dimension is inherent to the platform rather than added to it. A vessel monitoring ocean conditions for environmental purposes and a vessel providing maritime domain awareness for security purposes are, at the hardware and data architecture level, the same vessel. The choice of application is a software and deployment decision, not a fundamental design constraint. For governments, port authorities and maritime operators looking to justify the investment in autonomous ocean monitoring infrastructure, the ability to serve multiple use cases from a single platform is a significant commercial and strategic advantage.

The Case for Dual-Use

The argument for dual-use ocean technology is as ecological as it is commercial. The ocean monitoring infrastructure that security and sovereignty require is the same infrastructure that marine conservation requires. Persistent surface surveillance detects illegal fishing as readily as it detects unauthorised vessel incursions. Continuous environmental monitoring generates the baseline data against which pollution events, biodiversity decline and ecosystem disruption can be measured. Subsurface inspection capability protects critical infrastructure and maps the ocean floor simultaneously.

IUU fishing results in an estimated loss of 11 to 26 million tonnes of fish annually, equivalent to between 20% and 50% of the global fish catch; a figure whose ecological consequences are as significant as its economic ones. The technology that allows a coastal state to monitor its exclusive economic zone for security purposes is the technology that allows it to enforce fisheries regulations, detect pollution violations and track the ecological health of its marine environment. These increasingly close activities are the same investment with multiple returns.
