Sound can provide a unique lens into the lives of marine animals. MBARI continuously monitors the ocean soundscape, analyzing acoustic data with advanced algorithms developed by our scientists and engineers.
Sperm whales (Physeter macrocephalus) rely on sound to find food. While seldom seen in local waters, our deep-sea hydrophone frequently records their distinctive vocalizations. We have learned that sperm whales are present offshore in California year-round and that some migrate seasonally.
The blue whale (Balaenoptera musculus) is the largest animal on Earth, but is difficult to study. MBARI’s Blue Whale Observatory—a network of acoustic instruments—gathers data on whale behavior, food supply, and ocean conditions to help us better understand this gentle giant.
MBARI research and technology can help decision-makers protect these endangered animals and the environments they depend on.
