AI Model “Hears” Whale Calls in Seismic Data

Bryde's whale surfacing in South China Sea

10 June 2026—Researchers repurposed an AI model designed for visual identification tasks to detect Bryde’s whale calls contained with seismic data collected in the South China Sea. A whale call can be visualized as a spectrogram, a “snapshot of sound” that shows how the frequencies of the sound signal change … Continue Reading »
