Long‐term acoustic monitoring of whale vocalizations offers valuable information on cetacean population biology and ecology and has become an essential tool for stock management. This study investigated seasonal and interannual variation in fin whale call characteristics off the west coast of South Africa using passive acoustic data across two periods: July 24, 2014 to January 13, 2017, and March 3, 2023 to September 27, 2024....
