Doggerland was a changing landmass between Britain and continental Europe, now largely covered by the North Sea. Researchers reconstruct its rivers and habitats using seismic surveys, sediment cores, and ancient environmental DNA. A 2026 study reported temperate tree DNA from more than 16,000 years ago and evidence that parts of the landscape survived the Storegga tsunami around 8,150 years ago. This is a real submerged landscape. A habitable environment is not, by itself, a newly excavated city or proof of occupation at every sampled location.
The sea hides a geography that once joined what are now separate shores. Bradford-led work mapped extensive buried terrain between the Norfolk coast and Dogger Bank, including former river systems. Sediment cores add another scale of evidence: material from particular layers can preserve traces of the plants and conditions that existed before the water arrived. The result is not a single dramatic photograph of a lost civilisation. It is a landscape reconstructed by connecting geological structure, environmental records, and archaeological questions.
The 2026 research analysed sedimentary ancient DNA from 252 samples across 41 marine cores. It reported oak, elm, and hazel earlier than expected and suggested that some wooded places could have supported people late in the Ice Age. It also found evidence that portions of Doggerland remained above water after the Storegga tsunami, challenging the idea that one wave erased the entire landmass at once. The eventual loss involved a changing coastline and rising sea levels. The open archaeological question is where communities lived within that changing environment, and which traces can still be recovered from beneath the seabed.

How the story unfolded.
- More than 16,000 years ago
Woodland traces
The 2026 analysis identifies temperate tree DNA in the submerged landscape’s older sediments.
- About 8,150 years ago
The Storegga tsunami
A major tsunami affects the region, while evidence suggests some land survives afterward.

A new environmental reconstruction
Researchers announce findings that revise the woodland and flooding history.
Where the evidence stops.
Environmental DNA and mapped rivers do not alone establish settlements or their populations. The 2026 findings concern sampled areas and should not be turned into a claim that the whole landscape survived unchanged or vanished in a single event.
