Many of the world's shark populations are in decline due to overexploitation and habitat loss. A better understanding of their population status, distribution and habitat requirements is vital to maintain viable populations. However, as many pelagic shark populations occur in remote offshore locations, understanding their habitat requirements, distribution and population status at a regional level is crucial to manage and protect long-lived shark species. Dr Charlotte Birkmanis highlights one way to find out where sharks are, why they are there and how climate change may impact them in Australian waters and the adjacent high seas. She also shares effective techniques to highlight the wonders of the oceans and help more people to become ocean ambassadors.
