Mission Statement


Is to significantly expand communication between dolphins and humans.

We are working towards this goal by using cutting-edge technology to:

  • Develop new systems to explore cetacean cognition, acoustic abilities and create a language interface.
  • Record cetacean sounds both above and below water in the broadest spectrum possible.
  • Analyze these cetacean sounds for harmonic patterns and communication value.
  • Use these analyzed sounds to play specific musical phrases and tones underwater -- back to the cetaceans -- while recording their contemporaneous responses.
  • Publish and share this research in scientific journals.
  • Assist in establishing new standards in the scientific grade recording and processing of marine mammal acoustics.
  • Play cooperative games with cetaceans in order to expand our understanding of interspecies alliances and non-verbal communication.
  • Produce and distribute dolphin recordings for integration into human culture.
  • Use dolphin images and recordings to inspire humanity towards greater stewardship of our oceans.
