If we look to the North Sea, which would have been Doggerland, if you were stood in the middle of Doggerland, you would be as far from the coast as you are from Prague to the modern-day coast. So actually we're thinking of whole terrestrial landscapes.
Skip to 0 minutes and 45 secondsAnd this is really key because when we start thinking about really big questions, for example human diaspora or dispersals out of Africa by our modern ancestors, anatomically modern humans, around the Indian Ocean, across this basin-- Sunda Basin-- and into Australasia, we begin to see how important the coast and important these continental shelves were that we might not only be able to find submerged archaeology but that it might be able to give us really important information and the unique opportunity to start looking at key questions about how these people moved and how humans originated. DR.

So with Beringia here with lowered sea levels, this would have provided a lowland, marshy environment that people could have moved across to access America. Similarly, the shallow coastal strip along it could provide a highway for people within skin boats to travel down into the Americas. DR.

So it can withstand these regressions and transgressions of the sea levels. And we know this is not just hypothetical because we have these outstanding submerged archaeological sites. For example, here in the Baltic Sea of Denmark, we have the site of Tybrind Vig, where not only we have this amazing organic preservation, but we've got decorated paddles and log boats themselves. And we also have a similar preservation here very locally in the south of the UK in the Solent where we have lithic material and worked wood also being preserved in the submerged context. DR.
Skip to 2 minutes and 35 secondsFRASER STURT: What's really important is while the Danes really led the worldness-- and we always joke in archaeology that the Danes have been there first in maritime archaeology-- but actually if you look at this map of the world and focus on the light blue areas, we're now where this potential stretches across the globe and has significance for everyone from the Japanese archipelago through down into India, the large expanse of the North Sea, and across into America and South America. So this has the potential to reshape not just how we think about localised, small-scale problems or the wonders of the amazingly beautiful carved paddles but actually has a global significance.
Skip to 3 minutes and 14 secondsAnd beyond this, the archives we use to tell these stories informs about the rate and nature of environmental change at a global scale. How rapidly did these landscapes inundate? What was it like to be in the southern North Sea where your ancestors may have hunted out in landscapes which were now the sea? So these are significant things which archaeologists need to think about, and it's also changed how we think about the nature of the sea itself. So submerged paleolandscapes may be not as inviting immediately as shipwrecks, but this is the big picture stuff that for me and for Helen we're really interested in.
