This episode is the second of two of my conversation with Martin Gibling.  In the first episode, we discuss fluvial deposits in the geological record and we trace the effect that the break-up of Pangea around 200 million years ago had on river systems.  In this episode, we address the history of the rivers of Europe and the Americas, as well as the impact of the recent ice ages on today’s rivers.  We end by considering how humans have changed rivers and their deposits throughout mankind’s history. Martin Gibling has spent a lifetime studying rivers and river sediments around the world.  He is Emeritus Professor in the Department of Earth and Environmental Sciences at Dalhousie University in Halifax, Nova Scotia in Canada.
