Refining Echolocation Detection with Calibrated Wavelet Filters
Sperm whale clicks are broadband and powerful, but they share the deep soundscape with transient noise that fools conventional detectors. This paper proposes a calibrated wavelet filter designed to match the Gabor-like shape of a sperm whale click, reconstructing the signal so that only impulsive click regions produce high peaks. The result is a measurable reduction in false detections without sacrificing true positives.
Ocean Ingestion: Could a Whale Swallow a Diver Whole?
A sperm whale's throat is large enough to swallow a human, but the mechanics of such an event are far from cinematic. The animal's esophagus is designed for squid, not scuba gear, and its instinct would be to reject anything unfamiliar. Understanding these biological limits sharpens our respect for ocean life.
