An AI-powered tool called OrcaHello is now detecting the calls of endangered southern resident orcas in real time. The system aims to reduce harmful underwater noise from ships, which research shows significantly impairs the orcas' ability to hunt. This effort focuses on the Salish Sea, where an estimated 76 of these orcas remain.
Facts First
- OrcaHello uses AI to detect orca calls in real time from an underwater audio livestream.
- The tool specifically tracks the endangered southern resident orca subspecies in the Salish Sea.
- Ship noise can reduce orcas' hunting success by 12.5% per additional decibel of maximum noise.
- A typical modern ship raises underwater sound levels by 12 to 17 decibels at low frequencies.
- The southern resident orca population is estimated at 76 individuals as of December 2025.
What Happened
An AI-powered tool named OrcaHello is being used to listen to orca calls in real time. The tool, developed during a 2019 hackathon, tracks the movements of the endangered southern resident orca subspecies by detecting their specific calls through an underwater audio livestream. The team trained a machine-learning model to recognize these calls to detect when pods approach ports.
Why this Matters to You
This technology represents a direct, non-invasive intervention to protect a critically endangered species that is a cultural and ecological icon of the Pacific Northwest. If successful, it could help stabilize the population of southern resident orcas, which consists of just three pods. For you, this means the potential preservation of a keystone marine species and the complex ecosystem it supports, which benefits coastal health and biodiversity.
What's Next
The real-time detection provided by OrcaHello may allow for immediate alerts to ships in the area, potentially prompting voluntary speed reductions or course adjustments to lower underwater noise. This could lead to a measurable decrease in the acoustic disturbance that hampers the orcas' hunting. The continued use and refinement of this AI model is likely to be crucial for the long-term monitoring and protection efforts for this subspecies.
