In an important breakthrough in deciphering dolphin language, researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water.

The key to this technique is the CymaScope, a new instrument that reveals detailed structures within sounds, allowing their architecture to be studied pictorially.

The resulting "CymaGlyphs," as they have been named, are reproducible patterns that are expected to form the basis of a lexicon of dolphin language, each pattern representing a dolphin 'picture word.'

Certain sounds made by dolphins have long been suspected to represent language but the complexity of the sounds has made their analysis difficult

Our ultimate aim is to speak to dolphins with a basic vocabulary of dolphin sounds and to understand their responses

This is uncharted territory but it looks very promising
