Dundee: What the city would have looked like 20,000 years ago under 0.6 mile thick ICE

Amazing visualization revealed what the city of Dundee would have looked like around 20,000 years ago, when the landscape was covered with a 0.6 mile thick ice cap that covered Scotland and much of it. North Sea.

A jaw-dropping portion of the presentation juxtaposes the modern cityscape with a cross section of the vast Ice Age ice mass, to resemble “The Wall” from the HBO adaptation of Game of Thrones.

The video was produced by glaciologist Max Van Wyk de Vries of the University of Minnesota and design expert Kieran Duncan of the University of Dundee when the former unexpectedly got stuck in Scotland during the lockdown.

The ice cap over Dundee, Van Wyk de Vries said, would have lasted until around 15,000 years ago, when the planet warmed. The retreat of the ice has carved out various landmarks including Dundee Law and the Tay Estuary.

The retreating ice has carved out various landmarks, including Dundee Law and the Tay Estuary – the latter is pictured here with ice from 15,000 years ago, with icebergs breaking away from the slick (left ) and as it appears today (right)

Mr Van Wyk de Vries explained that he visited his Dundee-based girlfriend last March when the UK and US went into custody to fight the spread of the coronavirus, and he became curious about the geological history of his new temporary home.

“I had been on a field trip to help set up weather stations in Patagonia as COVID-19 started to spread around the world, so I got caught up a bit and couldn’t return in the United States, ”he said.

“When we weren’t allowed to leave our area during the lockdown, my girlfriend and I spent a lot of time exploring Dundee and the small area beyond that we could visit for exercise.

“It made me think of those beautiful landscapes and how they were shaped by flowing ice.

‘I was working remotely [over a distance of 3,600 miles] but i missed doing something local so i thought it would be an opportunity to work in my immediate surroundings, learn more about how it became what it is and recreate what it would have looked like 20,000 years ago.

“I studied a number of old papers using local data and ice models to calculate what this massive glacier would have looked like. I also looked at satellite images of glaciers that still exist in Greenland to get an idea of ​​what they might have looked like in Scotland.

Seeking to make his research findings more accessible, Van Wyk de Vries partnered with Duncan to create the visualization with public funding from the British Society for Geomorphology.

'Part of the film shows what a kilometer is [0.6 mile thick] The ice cap would have seemed above the law, and I remember my mind was blown away when Max first told me about it, ”Mr. Duncan said.  The Law (pictured here showing the relative height of the ice sheet) is Dundee's highest point - a 571-foot (174-meter) high remnant of a volcanic sill

The Law is Dundee’s highest point – the 571-foot (174-meter) high remnant of a volcanic sill that formed 400 million years ago.

“You hear numbers like that, but it’s only when you see what it would have been like in relation to something like the Law, which dominates the city, that you really start to understand how great this glacier was. massive, ”he added.

“This has been a fantastic project to work on, because it’s a great way to show people how their environment has become what it is. “

The researchers’ completed three-minute visualization is on display in the “Time & Tide: The Transformation of the Tay” exhibit at McManus: Dundee’s Art Gallery and Museum through October 3, 2021.

GREAT BRITAIN DURING THE LAST ICE AGE

The last glacial maximum occurred around 22,000 years ago, when much of Europe was covered in ice.

During the Ice Age, which ended about 11,500 years ago, ice covered about 30% of the world’s land.

In Britain, glacial ice and water flows extended south to the Bristol Channel.

Average temperatures were 5 ° C (8 ° F) cooler than today, allowing a kilometer-thick layer of ice to cover much of the country.

The temperature remained below 0 ° C all year round in northern areas, especially Scotland, allowing the leaf to remain on dry land all year round.

Ice connected Britain to Scandinavia, allowing a multitude of wildlife to roam freely between the UK and mainland Europe.

During this time, Britain is said to have seen woolly mammoths, giant deer and wolves roaming its icy planes.

Large glacial lakes covered Manchester, Doncaster, Newcastle and Peterborough, and much of the country was uninhabitable for humans.

Fast-flowing corridors of ice, known as Ice Streams, flowed east over Edinburgh and west from Glasgow.

All of Ireland was covered in ice, which flowed through the Irish Sea where it met the Welsh ice, then flowed south towards the Isles of Scilly.

Much of Scotland, Wales, the Midlands and northern England was covered in perpetual ice.

Cambridge, which was covered with a huge glacial lake, was the southernmost region to be strongly affected by the frigid climate.

Over time, ice and its powerful water flows carved out the land of Britain, forming geological scars that can still be seen today.

These include glacial ridges sculpted by moving ice and winding rock flows that have traveled for miles across the country.
