In this episode we talk to Phil Gibbard about the Pleistocene glacial history of eastern England and how to date the multiple glacial advances that took place over time. Phil has spent a long career working on glaciations across England and further afield and is known for collaborating with researchers on the continent in an attempt to come up with a holistic view on the Pleistocene geological history of the North Sea region. Phil also touches on the history of the Fenland in eastern England, how the current landscape was formed and deformed and the influence of bedrock geology onto glacial advance.
