I'm working on mobile apps to help researchers study dolphin acoustic communication, such as DC Dolphin Communicator 2019 which is free and open source on gitlab: https://play.google.com/store/apps/details?id=sm.app.dc&hl=e...

During a sabbatical trip in the Canadian Arctic in 1975, I came in close proximity with a beluga in Hudson Bay and was impressed with the unusual vocalizations which was in-air and about 3 feet from me. The beluga was tragically killed by Inuit a few minutes later. That's how my interest started. I later learned the basics from two people who were leaders in this field.
