"Biotwang" mystery call

New publication out on "mystery" call from the Mariana Trench Marine National Monument

During the analysis of the Autonomous Passive Acoustic Monitoring of Marine Mammals in the Pacific project, we discovered a complex baleen whale call that hasn't been described before.

Our published description just came out in JASA-EL, and can be found here.

Take a listen ...what do you think it cold be??
