Welcome to What’s Your Map? In this episode, Jerry speaks to Elizabeth Hogan, a marine biologist, Programme Director at the National Geographic Society, and a passionate advocate for marine conservation. 

Having spent over 15 years dedicated to protecting marine ecosystems, Elizabeth shares her experience while discussing a unique map that reorients our understanding of the world's geography.. She explains how this ocean-centric map from the Environmental Systems Research Institute illustrates the reality of our planet's interconnected bodies of water: that we have one global ocean rather than distinct, isolated seas.  

Elizabeth also reveals the significance of ocean currents, which are prominent on the map. She explains how they link distant regions, affecting everything from the migration patterns of marine species to the transportation of plastic waste, and the lives of coastal communities.

From historians, scientists and writers to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries.

So if you’re fascinated by history, art, adventure and culture, why not become part of a global community of fellow explorers as we ask - What’s your map?
