Image of the Week – Karthaus Summer School 2018

Nearly every year since the late 90s, during the summer, the picturesque Karthaus has hosted 10-day glaciology course. This school is a platform for glaciologists to explore, learn and expand their knowledge base. This helps researchers become multi-faceted: to view glaciology from the perspective of those specializing in other backgrounds such as hydrology, geomorphology, oceanography, etc. which ...[Read More]

Image of the Week –  Promoting interdisciplinary science in the Arctic: what is IASC?

The Arctic is one of the fastest changing regions on the Earth, where climate change impacts are felt both earlier and more strongly than elsewhere in the world. As an integral part of the Earth system, the Arctic is shaped by global processes, and in turn, Arctic processes influence the living conditions of hundreds of millions of people at lower latitudes. No one country or community can underst ...[Read More]

Image of the Week – Alien-iced

What do Chile and Jupiter’s moon Europa have in common? If you like astronomy, you may reply “space missions!” – Chile’s dry air and clear skies make it an ideal location for telescopes like the VLT or ALMA, while Europa’s inferred subsurface ocean will be studied by the upcoming mission to Jupiter JUICE, due to launch in 2022. But Chile’s high altitude Atacama desert and Europa’s frozen surface a ...[Read More]

Do clouds affect melting over Antarctic ice shelves?

The Antarctic Peninsula is the ‘canary in the coalmine’ of Antarctic climate change. In the last half-century it has warmed faster than most other places on Earth, and considerable change has consequently been observed in the cryosphere, with several ice shelves collapsing in part or in full. Representing this change in models is difficult because we understand comparatively little abo ...[Read More]

Image of the Week – On thin [Arctic sea] ice

Perhaps the most enduring and important signal of a warming climate has been that the minimum Arctic sea ice extent, occurring each year in September, has declined precipitously. Over the last 40 years, most of the Arctic sea ice has thus been transformed to first-year ice that freezes in the winter and melts in the summer.            Concern about sea ice extent and area is valid: since sea ice i ...[Read More]

Image of the Week — Cryo Connect: connecting cryosphere scientists and information seekers

Communicating scientific findings toward non-experts is a vital part of cryosphere science. However, when it comes to climate change and its impact, the gap between scientific knowledge and human action has never been so evident (see for instance, the publication of the latest IPCC special report). Today, our image of the week features an interview with Cryo Connect, a new initiative for more effi ...[Read More]

Image of the Week – Greenland’s fjords: critical zones for mixing

Image of the Week – Greenland’s fjords: critical zones for mixing

One of the most challenging research questions to address in the Arctic is how freshwater discharge from Greenland’s largest glaciers affects the biogeochemistry of the ocean. Just getting close to the calving fronts of these large marine-terminating glaciers is difficult. Fjords, hundreds of kilometers long and full of icebergs which shift with the wind and roll as they melt, make the commute a l ...[Read More]

Image of the Week – Oh Sheet!

The Antarctic and Greenland ice sheets are major players in future sea level rise. Still, there is a lot about these ice sheets we do not understand. Under the umbrella of the World Climate Research Programme, the international scientific community is coming together to improve ice sheet modelling efforts to better grasp the implications of climate change for ice sheet evolution, and consequently, ...[Read More]

Image of the Week – The 2018 Arctic summer sea ice season (a.k.a. how bad was it this year?)

With the equinox this Sunday, it is officially the end of summer in the Northern hemisphere and in particular the end of the melt season in the Arctic. These last years, it has typically been the time to write bad news about record low sea ice and the continuation of the dramatic decreasing trend (see this post on this blog). So, how bad has the 2018 melt season been for the Arctic?   Yes, the 201 ...[Read More]

Image of the Week – Climbing Everest and highlighting science in the mountains

Dr Melanie Windridge, a physicist and mountaineer, successfully summited Mount Everest earlier this year and has been working on an outreach programme to encourage young people’s interest in science and technology. Read about her summit climb, extreme temperatures, and the science supporting high-altitude mountaineering in our Image of the Week. It’s bigger than it looks! Experiencing the majesty ...[Read More]
