Archeologists discover a stone age atlantis beneath Danish bay, preserved like a time capsule after 8,500 years

Global sea levels rose after the last ice age

Rising sea levels preserved history “like a time capsule”

Below the dark blue waters of the Bay of Aarhus in northern Denmark, archaeologists search for coastal settlements swallowed

This summer, divers descended about 8 meters (26 feet) below the waves close to Aarhus, Denmark’s second-biggest city, and collected evidence of a Stone Age settlement from the seabed.

It’s part of a 13.2 million euro ($15.5 million) six-year international project to map parts of the seabed in the Baltic and North Seas, funded

The goal is to explore sunken Northern European landscapes and uncover lost Mesolithic settlements as offshore wind farms and other sea infrastructure expand.

Most evidence of such settlements so far has been found at locations inland from the Stone Age coast, said underwater archaeologist Peter Moe Astrup, who’s leading underwater excavations in Denmark.

“Here, we actually have an old coastline. We have a settlement that was positioned directly at the coastline,” he said. “What we actually try to find out here is how was life at a coastal settlement.”

After the last ice age, huge ice sheets melted and global sea levels rose, submerging Stone Age settlements and forcing the hunter-gatherer human population inland.

About 8,500 years ago, sea levels rose

Moe Astrup and colleagues at the Moesgaard Museum in Højbjerg, just outside Aarhus, have excavated an area of about 40 square meters (430 square feet) at the small settlement they discovered just off today’s coast.

Early dives uncovered animal bones, stones tools, arrowheads, a seal tooth, and a small piece of worked wood, likely a simple tool. The researchers are combing the site meter

They hope further excavations will find harpoons, fish hooks or traces of fishing structures.

“It’s like a time capsule,” Moe Astrup said. “When sea level rose, everything was preserved in an oxygen-free environment … time just stops.”

“We find completely well-preserved wood,” he added. “We find hazelnut. … Everything is well preserved.”

Excavations in the relatively calm and shallow Bay of Aarhus and dives off the coast of Germany will be followed

The sea level rise thousands of years ago submerged, among other things, a vast area known as Doggerland that connected Britain with continental Europe and now lies underneath the southern North Sea.

Submerged tree stumps preserved in mud and sediment can be dated precisely, revealing when rising tides drowned coastal forests.

“We can say very precisely when these trees died at the coastlines,” Moesgaard Museum dendrochronologist Jonas Ogdal Jensen said as he peered at a section of Stone Age tree trunk through a microscope.

“That tells us something about how the sea level changed through time.”

“It’s hard to answer exactly what it meant to people,” Moe Astrup said. “But it clearly had a huge impact in the long run because it completely changed the landscape.”
