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

Allen Pope November 9, 2018

IASC, the International Arctic Science Committee, is more than your regular committee. IASC connects Arctic scientists from 23 member countries and countless disciplines in order to promote and support impactful multi- and interdisciplinary Arctic research. IASC aims to foster a greater scientific understanding of the Arctic region and its role in the Earth system [Credit: 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 – On thin [Arctic sea] ice

Chris Horvat October 19, 2018

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

Céline Heuzé September 21, 2018

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 – The shape of (frozen sea) water

Adam Bateson September 7, 2018

Polar sea ice exists as isolated units of ice that we describe as floes. These floes do not have a constant shape (see here for instance); they can vary from almost circular to being jagged and rectangular. However, sea ice models currently assume that all floes have the same shape. Much focus has been paid to the size of floes recently, but do we also need to reconsider how floe shape is t ...[Read More]

What’s on at POLAR18?

Emma C. Smith June 13, 2018

Next Tuesday (19th June) the POLAR18 Open Science Conference kicks off in Davos, Switzerland. We have put together a quick guide about events that might be of interest to you during the week! Conferences are about the science, of course, but the social side is just as important 🙂 What is POLAR18? The eagle-eyed among you will have spotted that the POLAR18 conference is, in fact, a collection of di ...[Read More]

Early career scientists studying polar climate are one lucky group! The 29 young scientists who took part in the 10 day Polar Prediction School this year were no exception. They travelled to Arctic Sweden to learn and discuss the challenges of polar prediction and to gain a better understanding of the physical aspects of polar research. The Year of Polar Prediction The Year of Polar Prediction (YO ...[Read More]

Image of the Week — Biscuits in the Permafrost

Eleanor Jones May 18, 2018

In Svalbard, the snow melts to reveal a mysterious honeycomb network of irregular shapes (fig. 1). These shapes may look as though they have been created by a rogue baker with an unusual set of biscuit cutters, but they are in fact distinctive permafrost landforms known as ice-wedge polygons, and they play an important role in the global climate. Ice-wedge polygons: Nature’s biscuit-cutter In wint ...[Read More]

Image of the week — Making pancakes

Lettie Roach and Maddie Smith April 27, 2018

It’s pitch black and twenty degrees below zero; so cold that the hairs in your nose freeze. The Arctic Ocean in autumn and winter is inhospitable for both humans and most scientific equipment. This means there are very few close-up observations of sea ice made during these times. Recently, rapidly declining coverage of sea ice in the Arctic Ocean due to warming climate and the impending likelihood ...[Read More]

Image of the Week — Seasonal and regional considerations for Arctic sea ice changes

Céline Heuzé April 20, 2018

The Arctic sea ice is disappearing. There is no debate anymore. The problem is, we have so far been unable to model this disappearance correctly. And without correct simulations, we cannot project when the Arctic will become ice free. In this blog post, we explain why we want to know this in the first place, and present a fresh early-online release paper by Ingrid Onarheim and colleagues in Bergen ...[Read More]

Image of the Week – Arctic changes in a warming climate

The Arctic is changing rapidly and nothing indicates a slowdown of these changes in the current context. The Snow, Water, Ice and Permafrost in the Arctic (SWIPA) report published by the Arctic Monitoring and Assessment Program (AMAP) describes the present situation and the future evolution of the Arctic, the local and global implications, and mitigation and adaptation measures. The report is base ...[Read More]
