Episode Keeping tabs on Fiordland’s sharks and researching our deep-sea realm

0:00 26:09

Using acoustic tags and a network of receivers attached to the seafloor, researchers are tracking the movements of sevengill sharks in Fiordland. They want to understand how these apex predators adjust to changing ocean temperatures, particularly during marine heat waves. Plus, an international collaboration involving a high-tech German research vessel is exploring New Zealand’s deep-sea realm.

Guests:

• Eva Ramey, PhD candidate, Victoria University of Wellington • Dr Alice Rogers, Victoria University of Wellington Coastal Ecology Lab • Dr Kareen Schnabel, NIWA • Professor André Freiwald, Senckenberg am Meer Research Institute • Dr Cornel de Ronde, GNS
