Do you know about OGGM-Edu? An open-source educational platform about glaciers and glacier modelling

Are you teaching about glaciers and looking for fun educational activities for your students? Are you planning a workshop about glacier modelling and want to make it interactive, with a low entry level? Are you interested in learning about glaciers and glacier modelling, and looking for a simple way to get started? On top of that, do you want to do all of the above without installing anything on y ...[Read More]

Did you know that glacier mass loss affects water resources?

The picture above shows a typical Kyrgyz summer yurt camp, located in the valley of Altyn-Arashan, Kyrgyzstan. The stream you see flowing through comes from the glacier-fed lake of Ala-Kul, the gorgeous turquoise water featured below. The families who live there during summer have done so for generations, and travel up with their herds of horses and cows. The stream provides the water they need fo ...[Read More]

Did you know there’s a place to Find, Discover, & Download Arctic Data? Meet The Arctic Data Center!

Getting data from the Arctic is often difficult and expensive – instead, stand on the shoulders of giants and investigate over 6000 datasets preserved for future download and reuse in the Arctic Data Center! Read on for more information about the Arctic Data Center and the data contained therein. The Arctic Data Center is the primary data repository for the Arctic section of the US National ...[Read More]

Did you know … that liquid water can be held within a glacier?

Hidden below the surface of some glaciers, liquid water can be found within what is called the firn layer – the upper layer of a glacier where snow compacts into glacier ice. Liquid water may persist there for up to many years, forming what scientists call “firn aquifers.” While observations of seasonal firn aquifers have existed since the mid to late 1900s in several mountain glaciers, recent stu ...[Read More]

Did you know… that you can read the edge of Greenland’s ice as an open book?

Did you know… that you can read the edge of Greenland’s ice as an open book?

Scientists struggle to get ice samples from the depths of glaciers where fundamental pieces of information about the climate of Earth are stored. But in many places around the periphery of the Greenland Ice Sheet, you don’t need to drill a deep ice core to obtain ancient ice, you can simply walk across the ice sheet’s margin and look at the layered ice surface. There you can read the ice as though ...[Read More]

Did you know…about regenerated glaciers?

Did you know…about regenerated glaciers?

Ice caps, valley glaciers, cirque glaciers, piedmont glaciers, ice sheets… I’m guessing that if you are a glaciology enthusiast, you have already heard about these types of glaciers. But you probably don’t know anything about regenerated glaciers, am I right? Well, you are in the right place! Let’s find out more about this little-known glacier type. Classifying glaciers Glaciers are classified on ...[Read More]

Did you know… the Andes are so cryo-diverse?

Extending for almost 8,000 km along the west of South America, the Andes are the longest continental mountain range in the world. They portray an impressive richness and diversity of cryospheric features, including: the most substantial extension of tropical glaciers on Earth, one of the highest densities of rock glaciers, the largest glacierized area in the Southern Hemisphere outside Antarctica, ...[Read More]

Did you know… about the ice content in mountain permafrost?

Did you know… about the ice content in mountain permafrost?

Through the eyes of a researcher studying mountain processes in the European Alps in the context of a global warming climate, let’s discover how geophysical methods help to better understand frozen ground! Permafrost defines a thermal state, i.e. permafrost is soil, sediment, or rock that remains at or below 0°C during at least two consecutive years. As permafrost is only defined by its temperatur ...[Read More]

Did you know… the surface of melting glaciers is one of the most radioactive places on Earth?

Did you know… the surface of melting glaciers is one of the most radioactive places on Earth?

Recent studies show that glaciers are significantly affected by pollution, and in general by human activities, but few people would imagine that their surface contains traces of nuclear contamination and radioactivity. It has been recently claimed that high amounts of radioactivity have accumulated on glaciers, only beaten by the radioactivity levels of sites where nuclear incidents and tests have ...[Read More]

Did you know… tropical cyclones cause large snowfall on Kilimanjaro’s glaciers?

Tropical cyclones are an important part of the weather in the southwest Indian Ocean each year, from November through April. These storms can cause massive destruction and loss of life when they make landfall, which happens most often on the islands of Mauritius and Madagascar and the coastal region of Mozambique. However, until recently, relatively little was known about their impacts on the high ...[Read More]
