How We Found And Explored the Land Lost Beneath the North Sea

10,000 years ago, a vast land connected Britain to Europe. Explore the ancient history of Doggerland beneath the North Sea. Before the rising oceans claimed the region, a lush landscape thrived between the modern coastlines of the United Kingdom and mainland Europe. We examine the North Sea geology and mapping data that reconstructs this lost world, showing exactly how the geography changed as ice sheets retreated at the end of the last glacial period. By analyzing geological samples and ancient coastlines, researchers have pieced together the environment of this prehistoric landmass. This documentary provides a look at the terrain that once supported human populations and wildlife, tracing the path of the submerged Britain connection before the rising tides turned it into the seabed we recognize today.
