Image of the Week — Last Glacial Maximum in Europe

Image of the Week — Last Glacial Maximum in Europe

During the last ice age*, ~70,000 to 20,000 years ago, the climate was much colder in Europe. As a result, the northern part of Europe was fully covered by the Fennoscandian (a.k.a the Scandinavian ) ice sheet, which extended up to the British Isles and some parts of Poland and Germany. In central Europe, the Alps were also almost fully glaciated. The storage of all this ice on the continent lower ...[Read More]

Image of the Week – Antarctic fieldwork 50 years ago!

Image of the Week – Antarctic fieldwork 50 years ago!

So far this blog has published many pictures of current polar field work campaigns. Today, we would like to take you back to Antarctic expeditions during the 1960s. The photos presented in this post date back from the Belgian-Dutch Antarctic field campaigns of 1964-1966. The first picture shows Ken Blaiklock (red overalls) with a Belgian surveyor. Ken was part of the 1955–58 Commonwealth Trans-Ant ...[Read More]

Image of the Week – Changes in the Greenland Ice Sheet Documented by Satellite

Monitoring the changing ice mass of the Greenland Ice Sheet provides valuable information about how the ice sheet is responding to changing climate, but how do we make these measurements over such a large area of ice? Using NASA’s GRACE satellites (twin-satellites flying in formation) it is possible to make detailed measurements of the Earth’s gravitational field. As ice is gained/lost from ...[Read More]

Image of the Week — Happy ValentICE’s day

On the eve of 14 February, love and little hearts are everywhere, even trapped in lake ice! The EGU Cryosphere blog team wishes you a happy Valentine’s Day 🙂 Behind this nice picture, there is also science This picture was taken during a laboratory experiment that aimed to reproduce the bubbles observed in Arctic lake ice in the winter. In this shot, we can see two types of gas bubbles in th ...[Read More]

Image of the Week — slush on top of sea ice

Many glaciologists look forward to going on fieldtrips and then, once they are back, they make us dream by posting breathtaking photos (like THIS or THIS or THIS). However, the reality of the field can sometimes be very different…. The picture illustrates how difficult it can be to work on sea ice when the snow on top of it starts to melt and forms slush (a mixture of snow and liquid water t ...[Read More]

Image of the Week: Icequakes! Stick-Slip motion under Western Greenland

Image of the Week: Icequakes! Stick-Slip motion under Western Greenland

The Greenland Ice Sheet contains enough fresh water to raise global sea level by around 6 m, therefore it is very important to understand how the ice moves from the interior of the ice sheet towards the oceans. Processes that happen at the base of the ice sheet, where the ice meets the bed, are known to be a key control on how the ice moves. Geophysical techniques, such as recording tiny icequakes ...[Read More]

Image of Week: Blue Ice in East Antarctica

Image of Week: Blue Ice in East Antarctica

The blue ice areas of Antarctica are one of the most fascinating parts of the ice sheet. In these regions, snowfall is so low that the ice is laid bare by the wind and consequently sublimates. This exposes beautiful, blue ice surfaces, like an ocean frozen in time. This picture was taken at a site named “Windy Corner” by the Kottas Mountains, in the northernmost part of the Heimefrontf ...[Read More]

Image of the Week — Greenland ice sheet and clouds

A new study combining satellite observations and model simulations shows that clouds increase meltwater runoff in Greenland by one-third compared to a cloud-free scenario. Precipitation effects not considered, clouds above the Greenland ice sheet reduce its Surface Mass Balance (SMB) [red in figure] compared to clear-sky conditions [blue in figure]. Because clouds trap the outgoing radiation from ...[Read More]

Image of the Week — Happy New Year

December 2014, 11:50 p.m., the sun licks the horizon on Derwael ice rise; It’s time to go back to the tent … The shot was taken during the 2014 IceCon Field campaign in East Antarctica (read Brice’s blog post  telllling about his first journey to Antarctica). Here, you can also read about the 2016 field season of the IceCon project, which started just a few days ago.

Image of the Week — Greetings from Antarctica

Image of the Week — Greetings from Antarctica

Christmas greetings from people at Rothera Research Station, Adelaide Island, Antarctica. Rothera, which is the British Antarctic Survey’s largest base in Antarctica, is a centre for marine biology and gateway for getting scientists into their deep field camps. Christmas Day is a regular working day for the staff of around 90. However the chefs will be getting everyone into the festive spiri ...[Read More]
