 Welcome back to Lost Frontiers and Drowned Landscapes in Britain and beyond. This is the second day after a day on Lost Frontiers, the North Sea and the West Coast of the UK. Today we're going big and we'll be seeing the results of wonderful projects around Britain and the world. There's going to be a few housekeeping notes just to say for the speakers that I have a large digital timer on my browser. That after 25 minutes of each presentation I will pop up magically to remind people that their time is nigh. All of the questions should be put through the chat and I'll give those at the appropriate time at the end of each lecture. So don't be shy but give us those questions when you can. Today we're starting off with someone who I'm sure everyone knows well, Geoff Bailey, who's going to be talking about the global context of Drowned Landscapes. Geoff is well known, I think, to everyone here. He's Emeritus Professor at the University of York, Visiting Professor at Flinders. He's got research interests everywhere, actually, in coastal prehistory. He's done it and he's worked pretty much everywhere as well. Europe, Australia, Africa. He had an advancement looking at Saudi Arabia, but he's PI on disperse, the dynamic landscapes, coastal environments and human dispersals. A partner investigator on the ARC, Deep History of Sea Country Project, and is a member of the ERCC, Change the Symmetry Project on Marine Ecosystems, and of course, very importantly, Chairman of the EU Action Splash Cause, Submerge Prehistoric Archaeology and Landscapes of the Continental Shelf. If that doesn't wet your appetite for this, nothing will. So I'm going to hand over to Geoff and I will be seeing him again in 25 minutes. Thank you very much.
