By Dr Alex Clark Why Ireland? Ice sheets provide valuable clues on how they behaved thousands of years in the past through the dramatic landscapes they create. And you may struggle to find a more elaborate signature than on the island of Ireland, scribbled out by the last British-Irish Ice Sheet approximately 30,000 to 15,000 […]

A long history of scientific debate Along the east coast of the UK, spectacular coastal sections expose sediments that were deposited by the last British Irish Ice Sheet (BIIS) around 21,000 years ago. For many years, Late Devensian

This article was written by Dr Hannah Bickerdike. The glaciation of the upland areas of Britain during the Younger Dryas left behind a distinctive system of landforms across Scotland, the Lake District, Snowdonia and the Brecon Beacons. Different parts of Britain were characterised by a different style of glaciation. See more on our Introduction to

This article was written by Dr Hannah Bickerdike. The Loch Lomond Stadial in Britain Between 12,900 and 11,700 years ago, gradual warming of Britain’s climate was interrupted by a sudden period of renewed cooling. During this period, known as the Loch Lomond or Younger Dryas Stadial, glaciers regrew in many areas of upland Britain. Evidence

By Dr Sam Roberson, British Geological Survey, Belfast Glaciation of Ireland during the Devensian The island of Ireland has been glaciated many times during the Quaternary period. The last glaciation in Ireland is referred to historically as the ‘Midlandian’, but now, the British-Irish term ‘Devensian’ is more commonly used. During the Devensian, the British-Irish Ice

The British-Irish Ice Sheet reached its most recent maximum extent around 27,000 years ago. It was drained by many fast-flowing ice streams, and reached the edge of the continental shelf around its northern border. In the south, it terminated near the Vale of York, with a lobe penetrating down the eastern coastline as far as

In this section, we discuss the evidence for the last British-Irish Ice Sheet (BIIS). Throughout the Quaternary (the last 2.6 million years), there have been many ice sheets in Britain. The ice sheet grows during cold periods (stadials) and recedes in warm periods (interstadials) like the one we live in today. The last BIIS began

It uses the glacial geomorphology and glacier reconstruction compiled by Bickerdike et al. (2016, 2018). We have used these data to produce
