A new glacier chronology from New Zealand

A new glacier chronology from New Zealand

In this week’s blog, Levan Tielidze tells us about the new glacier history from the Southern Alps of New Zealand, an important piece of information to better understand the climatic history of Earth during the Quaternary, the current geologic period. Quaternary glaciations Geochronological dating of glacial moraines is useful for determining the extent and timing of past glaciation and for reconst ...[Read More]

Cryo Adventures – Droning on glaciers and ice caps in Kyrgyzstan

Cryo Adventures – Droning on glaciers and ice caps in Kyrgyzstan

Drones are not only a cool toy to play with. They are also a useful instrument to monitor and study glaciers and ice caps. By taking thousands of images flying above the ice, we can make 3D models of ice masses at centimetre resolution. Using drones, we can now survey small to medium sized glaciers and ice caps in unprecedented detail. In recent years, we have conducted several surveys on glaciers ...[Read More]

Did you know… that glaciers can sing?

Did you know… that glaciers can sing?

Have you ever wondered what the voice of a glacier sounds like? Well, listen here! And if you want to know how the glacier makes these sounds, then let’s take a walk on the ice side… Close your eyes and think of the time you were in the middle of the mountains. On a snow plain, a glacier or a frozen lake; just you. You hear your footsteps in the snow, crunching ice. The wind blows through your hoo ...[Read More]

Crater Glacier: A story of renewal in the aftermath of destruction

Crater Glacier: A story of renewal in the aftermath of destruction

Crater Glacier, located on Mount St. Helens, Washington State, U.S., tells a tale of renewal. The catastrophic and deadly May 18th, 1980 eruption of the volcano created, among other things, a deep horseshoe-shaped, north-facing crater and obliterated most of the glaciers that resided on the volcano’s slopes. By a decade and a half later, it was clear that a glacier had formed in this unlikely loca ...[Read More]

Time & space of glaciers

Time & space of glaciers

People usually perceive space and time, comparing them to their own life Words such as “forever” and “until the end” appear in fiction But how can we imagine the space and time of the mountain glaciers whose existence goes beyond our usual perception? And why is it so important for us now? With this post, researcher Alexandra Rogozhina shares her thoughts on these suggestive topics. Mostly, ...[Read More]

The new glacial geomorphological map from New Zealand

The new glacial geomorphological map from New Zealand

Geomorphological maps are a fundamental tool to represent landforms and understand how different morphological elements and agents shaped a natural landscape. They are also important as background information for many fields of research including ecology, forestry and of course, glaciology. In this week’s blog, Levan Tielidze tells us about the importance of mapping glacial geomorphology, presenti ...[Read More]

Climate Change and Cryosphere – What can we learn from the smallest, most vulnerable glaciers in the Ötztal Alps?

The Alps were the first mountains to be studied from a glaciological point of view in the 19th century and they host some of the most studied glaciers of Earth. Some of them are found in the Central Alps and in particular, the Ötztal Alps. Just to cite the most known and largest glaciers in this Alpine sector, we can mention Hintereisferner or Vernagtferner. But in the Ötztal Alps you can also fin ...[Read More]

Image of the Week – Why is ice colourful?

Image of the Week – Why is ice colourful?

When you think of glacier ice, what colour first springs to mind? Maybe white, blue or transparent? Well, glacier ice can, in fact, be mesmerising and multi-coloured! Our image of the week shows thin sections of glacier ice under polarised light. These sections were cut from block samples of two Alpine glaciers in Switzerland (Chli Titlis and Grenzgletscher).   In these images the individual ice c ...[Read More]
