As birds welcome dawn around the islands of the Gulf, there’s a similar ‘salty dawn chorus’ happening beneath the waves.

The deployment of six New Zealand designed hydrophones around the Gulf has enabled University of Auckland PhD candidate Rosalyn Putland to document daily, lunar, and seasonal cycles and provide a new perspective of our marine environment.

She talks to the Gulf Journal about her work, describing the soundscape she is recording as "an orchestra".
