- Whale songs were discovered accidentally during Cold War submarine tracking, leading to Roger Payne's pivotal research.
- Passive acoustic monitoring uses soundscapes to understand ecosystems, with modern machine learning aiding analysis.
- Dinacon 2025 workshop focused on building inexpensive hydrophones for bioacoustic field recordings.
- Stereo hydrophones were developed to better capture underwater soundscapes by using multiple hydrophones at different depths.
- A $5 hydrophone construction workshop was conducted, detailing the build process and required components.
- Seastream, an underwater radio station, was prototyped but faced connectivity and social challenges.
- A tool called Dinacon Hydrophone Explorer was created to listen, annotate, and share observations from long bioacoustic recordings.
