Meeting Tracey Rogers

As a young girl, Tracey Rogers was inspired by deadly sea creatures. It became a passion that led to her becoming the only biologist in the world committed to a long-term study of the Leopard Seal.

Recognised as the world's leading expert on these top predators, Tracey has spent the last decade seeking to solve the mysteries of the Leopard seal's communication, foraging habits and territorial range.

Her studies now focus on how changes in the Southern Ocean, driven by climate change, will affect the leopard seal. And, because the currents in Antarctica and the Arctic Circle are the "conveyer belts" of all ocean currents, Tracey's work is vital to us all.
