Image of the Week – How ocean tides affect ice flow

Image of the Week – How ocean tides affect ice flow

Ice streams discharge approximately 90% of the Antarctic ice onto ice shelves , and ultimately into the sea into the sea (Bamber et al., 2000; Rignot et al., 2011). Whilst flow-speed changes on annual timescales are frequently discussed, we consider here what happens on much shorter timescales! Previous studies have shown that ice streams can respond to ocean tides at distances up to 100km inland ...[Read More]

Image of the Week – Canyons Under The Greenland Ice Sheet!

Image of the Week – Canyons Under The Greenland Ice Sheet!

The Greenland Ice Sheet contains enough water to raise sea level by 7.36 meters (Bamber, et. al. 2013) and much of this moves from the interior of the continent into the oceans via Jakobshavn Isbræ – Greenland’s fastest flowing outlet glacier. An ancient river basin hidden beneath the Greenland Ice Sheet, discovered by researchers at the University of Bristol, may help explain the loca ...[Read More]

Marine Ice Sheet Instability “For Dummies”

Marine Ice Sheet Instability “For Dummies”

MISI is a term that is often thrown into dicussions and papers which talk about the contribution of Antarctica to sea-level rise but what does it actually mean and why do we care about it? MISI stands for Marine Ice Sheet Instability. In this article, we are going to attempt to explain this term to you and also show you why it is so important. Background The Antarctic Ice Sheet represents the larg ...[Read More]

Image of the Week – Mushrooms at zero degrees = hair ice?!

Image of the Week – Mushrooms at zero degrees = hair ice?!

  When you go down to the woods today you’re in for a big surprise….. hair ice!  Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year-old theory states that hair ice a ...[Read More]

Image of the Week – Storing water in Antarctica to delay sea-level rise

Image of the Week – Storing water in Antarctica to delay sea-level rise

  Sea level rise Sea-level rise is one of the main impacts of the current global warming and its rate has dramatically increased in the last decades (the current rate is about 3 mm per year). Even if greenhouse gas emissions were stopped today, sea level would continue to rise due to the slow Earth climate system response (IPCC, 2013, chap. 13). It is therefore a considerable threat for popul ...[Read More]

When Cryospheric Research Transforms Lives

When Cryospheric Research Transforms Lives

My name is Kathi Unglert, and I’m reporting from the EGU 2016 General Assembly as part of the EGU student reporter programme. Below is my second contribution to the Cryosphere Blog – this time about how cryosphere research can have a real impact on people’s lives. Antoni Lewkowicz – he’s famous, according to a comment I overheard in Tuesday’s PICO session on applied geophysics in cryosphere ...[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: 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 the Week: Under the Sea

Image of the Week: Under the Sea

Always wondered how it looks like under the sea ice? Getting an answer is simpler than you might think: Just go out to the front of McMurdo ice shelf in Antarctica and drill a tube into the sea ice. Then let people climb down and take pictures of the ice from below. More information: – Photo taken by Marcus Arnold, Gateway Antarctica, University of Canterbury during his November 2015, Antarc ...[Read More]
