Sea levels have risen and fallen repeatedly over the last 2 million years. During low sea levels, large tracts of land were exposed along coastlines around the world, creating new habitats for plants, animals, and people to inhabit and new routes for people to move around the world. Now, many of these places are underwater, but evidence of these ancient landscapes, and the people who occupied them, still exists. In this episode we chat with Geoff Bailey and Hayley Cawthra about the challenges of working in coastal environments and reconstructing their submerged stories.
