Our Changing World: Tracking sevengill sharks in Fiordland

On Our Changing World, we hop onboard the Department of Conservation boat Southern Winds in Doubtful Sound, Fiordland.  

The team are doing scientific dives to document the different habitats in the sound.  

They are also collecting some black corals and sea sponges for research back in Victoria University of Wellington’s Coastal Ecology Lab.  

Onboard are PhD candidate Eva Ramey and her supervisor Dr Alice Rogers. Both are part of the dive team for this expedition, but they are also involved in another piece of Fiordland science: using acoustic tags to track sevengill sharks.  

During a break in the dive action, Claire Concannon caught up with Dr Alice Rogers to learn more.
