Network on Arctic Glaciology (NAG) - The Importance of Arctic Glaciers for the Arctic Marine Ecosystem
When: 22-24 January 2018 | Where: Obergurgl (Austria) | Contact: Thorben Dunse
The workshop integrated two special activities. The first, “Understanding atmosphere-glacier-ocean interactions and their implications for the pan-Arctic glacier mass budget” represents a long-term strategy of the Cryosphere Working Group and NAG. The second theme broke new ground: an IASC cross-cutting activity of the Cryosphere and Marine working groups of IASC, addressing “The importance of Arctic glaciers for the Arctic marine ecosystem”.
Interdisciplinary work requires that researchers from the involved disciplines get to know each other and learn to understand each-others scientific jargon. The IASC cross-cutting activity contributed in building a bridge between the cryosphere and biosphere community. NAG aims to elaborate this initiative in the years to come and work towards the involvement of members from other relevant disciplines, such as physical oceanography, ocean biogeochemistry, as well as terrestrial ecology.
The next workshop on the dynamics and mass balance of Arctic Glaciers and Network on Arctic Glaciology annual meeting will be held at Bardøla Hotel in Geilo, Norway, 20-24 January 2019. More information will be distributed via Cryolist and the IASC-NAG website until summer 2018.
• Present and discuss new results on observations and modelling of the dynamics and mass budget of Arctic glaciers, including the Greenland ice sheet.
• Provide a forum for glaciologists and marine biologists to present and discuss their work and to stimulate future collaborations.
• Plan and coordinate field work with the aim of using available infrastructure and logistics in the most efficient way.
The Frozen-Ground Cartoon
How does a reindeer experience climate change? Can a turkey melt? And why is research in the Arctic better than holidays on the beach? Two artists and twelve scientists provide a completely new perspective on the Arctic.
The Frozen-Ground Cartoon is a series of brand-new comics about permafrost, funded by the International Permafrost Association (IPA) with additional support from IASC (Terrestrial and Cryosphere WGs). The project has so far produced 22 pages of comics through an iterative process of exchanging ideas between two artists and thirteen scientists. The comics are available for free download through the project web page The Frozen-Ground Cartoon, in English and Swedish, and printed copies have so far been handed out to school kids and general public in Europe and North America.
(1) Distribute the comics as wide as possible.
(2) Work towards translations into more languages.
(3) Evaluate the effectiveness of the science communication through the comics, in collaboration with schools and pedagogic experts.
3rd Snow Science Winter School
When: February 2017 | Where: Sodankylä (Finland) | Contact: Juha Lemmetyinen

Ilulissat Climate Days Workshop
When: 02 - 05 June 2015 I Where: Ilulissat, Denmark
Cryosphere changes in Greenland and the Arctic are spectacular manifestations of global climate change, and have made Greenland quite a “hotbed” for international science in recent years. The “Ilulissat Climate Days” was aimed to give a status of current changes in the Greenland cryosphere (ice sheet, icecaps, glaciers, and sea ice changes), especially in order to report and discuss the rapid changes of the last few years, as seen from a variety of in-situ, airborne and remote sensing data, as well as understanding the processes of the rapid changes. The meeting was also intended to provide an opportunity for local and regional stakeholders to get updated information on the current changes, and many representatives of the Greenland parliament and government bodies, as well as local people from Ilulissat, participated at various stages of the conference.
The Ilulissat Climate Days was a follow up the highly successful Nuuk Climate Days 2009, and at the same time served as the final conference of SVALI (Stability and Variations of Arctic Land Ice), a Nordic Council of Ministers Center of Excellence research project, focussing on changes and glaciological processes across all Nordic ice caps (Scandinavia, Svalbard, Iceland as well as Greenland). Several stakeholders and media people from the Nordic countries participated in this activity as well.
Overall a total of 179 participants was registered for the Ilulissat Climate Days, with a good mix of young scientists (Ph.D. students and postdocs), experienced researchers, stakeholders and politicians, including several officials from the European Space Agency as well.

1st European Snow Science Winter School 2015
When: 08 - 14 February 2015 I Where: Sodankylä, Finland
Snow is a key component of the cryosphere. Snow grain size (microstructure) of snow is relevant to most physical properties of the snowpack, as albedo, radiative transfer of microwaves, thermal conductivity, trafficability, air permeability. Responding to the recommendation by a recent workshop (Snow Grain Size Intercomparison Workshop 2014), underlined the need to teach modern techniques of snow microstructure characterization to a wider community, especially to graduate and post-graduate scientist. An improved quantification of snow properties is highly relevant to understand the changing arctic snowpack.
In this workshop we will teach the state-of-the-art snow measurement techniques, both direct and indirect methods that were developed and are being used by different groups. The focus of this workshop lies on field measurements, combined with theoretical lessons in the classroom. Field measurements will be done in small groups of 3-4 students. Each group of students will have to prepare a report describing the methods, results and interpretation. The course corresponds to 3 ETCS-Points.
