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 […]

Snow How do we build a glacier? We start with a snowflake. Snow, over time, is compressed into firn, and then into glacier ice. Snow falls in cold regions, such as mountain tops or in polar regions. In glaciology, snow refers to material that has not changed since it fell1. Snow is very light and

There are many ArcGIS Story Maps around. Some are better than others; some take too long to load or are not well thought through. But some are excellent. Asia’s melting glaciers This well made Storymap focuses on melting glaciers in High Mountain Asia, and the impact this will have on water resources. Who owns Antarctica?

This page was contributed by Dr Frances Butcher from Sheffield University. What is an esker? Eskers are ridges made of sands and gravels, deposited by glacial meltwater flowing through tunnels within and underneath glaciers, or through meltwater channels on top of glaciers. Over time, the channel or tunnel gets filled up with sediments. As the
Welcome to the Younger Dryas Glacial Map! Here, you can explore the glaciation of the UK during the Younger Dryas glaciation. In the UK, this period is also called the “Loch Lomond Stadial”. At this time (12,900 to 11,700 years ago), there was a period of abrupt cooling. Glaciers began to grow again in much

“Fluvioglacial” or “glaciofluvial” means erosion or deposition caused by flowing meltwater, from melting glaciers, ice sheets and ice caps. Glacial meltwater is usually very rich in sediment, which increases its erosive power. Glaciofluvial landforms include sandar (also known as outwash plains; they are braided, sediment-rich streams that drain away downslope away from a glacier), kames

Glaciofluvial landforms are landforms created by the action of glacier meltwater. They can be erosional, or depositional landforms, and can form underneath, on top of, in front of, and around the edges of former glaciers.

Glaciers are one of the most powerful forces shaping our local landscape. As glaciers flow downhill from mountains to the lowlands, they erode, transport, and deposit materials, forming a great array of glacial landforms. They can erode mountains, and change their morphology. Large glaciers and ice sheets can deposit great swathes of sands and gravels,

What are meltwater channels? Each year, glaciers melt. Meltwater channels are erosional features, cut into rock and sediment by flowing water beneath or close to ice-sheet margins1,2. They can cut sizeable troughs, meaning that they are very visual indicators of the location of the former ice margin. Meltwater channels can therefore be used to work
