Tagging study reveals new insights into iconic humpback song

Researchers attached non-invasive recording tags to 16 male humpback whales off Maui between 2018 and 2024, mapping humpback whale songs to complete dive cycles for the first time and revealing how physical strain shapes vocal displays—a breakthrough that solves a long-standing biological puzzle and offers marine conservationists a new passive acoustic monitoring tool to detect ocean noise disruption.

The findings are from field observations and tagging data; applying this to real-world marine noise monitoring will require further deployment and validation.
