Scientists have developed a new autonomous underwater robot capable of tracking sperm whale communication in real time, marking a major advance in marine research. The system, created by Project CETI, uses a glider equipped with hydrophones to detect the whales’ distinctive clicking sounds, known as codas, and automatically steer toward them. Unlike traditional tracking methods such as suction tags or fixed sensors the robot can make decisions underwater as events unfold, allowing it to follow individual whales or groups continuously for extended periods, potentially lasting months.
This breakthrough enables researchers to study whale behaviour, social interactions, and communication patterns with unprecedented detail, including how calves learn vocalizations and how whales respond to human-generated noise. The data gathered could inform more effective conservation strategies, such as adjusting shipping routes or fishing practices to reduce disruption. While challenges remain, the technology represents a significant step toward understanding complex marine life communication and improving protection of ocean ecosystems.
