The Future of Permafrost in a Climate-Changing World, Workshop at EGU 2015, Vienna

LogoPermafrost Young Researchers Network (PYRN) together with the Association of Polar Early Career Scientists (APECS) will be organizing a short course about "The future of permafrost in a climate-changing world" during the EGU 2015.
The course is open for Bachelor, Master, PhD students and post-docs and the goals are: 1) to equip young researchers with a multidisciplinary understanding of the role of permafrost in the climate system; 2) to strengthen international collaboration of early career researchers; and 3) to enable the participants to put their research into a larger context. The objective of the course is to revise recent research that concerns permafrost in a changing climate. Participants will learn about the effect of permafrost development and degradation in polar and mountain regions, and its impact on infrastructures and ecosystems under climate warming scenarios.

10h30: Introduction
10h45: Climate scenarios
11h00: Permafrost modelling during future scenarios
11h30: Landscape dynamics
11h45: Hazards and infrastructure
12h00: Discussion and closing remarks

To celebrate the 10th anniversary of PYRN and the 1st year anniversary of APECS Austria, a Social Event will be held in the evening in a Heuriger - a traditional Austrian tavern.
All workshop participants are invited for a traditional buffet. Beverages are self-payed.Time: 20h00. Location: "Zum Berger", Himmelstraße 19, A-1190 Wien.

Getting there from the city center: alternative 1) tram nr 38 from "Schottentour" to the end station "Grinzing" alternative 2) subway U4 from "Schwedenplatz" to "Heiligenstadt", change to bus 38A and get of at "Grinzing".
We hope to see many of you there!

New PAGE21 - ADAPT publication on permafrost degradation and land cover changes

RIMG0463New PAGE21 / ADAPT publication called "Assessing permafrost degradation and land cover changes (1986-2009) using remote sensing data, Umiujaq, sub-Arctic Quebec" is out. The publication is authored by Inga Beck, Ralf Ludwig, Monique Bernier, Esther Lévesque and Julia Boike.

The paper introduces results on quantification of recent land cover changes in the Umiujaq region of northern Québec, Canada

The paper is published by Wiley OnlineOpen and can be accessed online HERE.









New PAGE21 publication on remote sensing

remote sensingThere is yet another new PAGE21 related publication "Land surface temperature retrieval over circumpolar Arctic using SSM/I–SSMIS and MODIS data" authored by  Cyrille André and Catherine Ottlé from CEA together with A. Royerb and F. Maignana from Université de Sherbrooke, Canada.

The paper presents how the researchers combine passive microwave and thermal infrared data to estimate land surface temperature during summer snow-free periods over northern high latitudes.

The paper was published in "Remote Sensing of Environment" and is accessible freely on the RSE journal website until 12 April here.



A Quarter of a Century of International Arctic Research Cooperation

iasc logoIn the context of its 25th anniversary this year, the International Arctic Science Committee (IASC) is pleased to present a comprehensive publication on its history from the planning process in the late 1980s until today.
Printed as a special issue of the IASC yearbook, the publication compiles and analyzes the history and development of IASC and its initiatives and achievements. A collection of historical documents, a film and a brochure presenting a timeline of the most important events in the development of IASC in the last quarter of a century complement the publication.
The book „IASC After 25 Years", edited by Odd Rogne, Volker Rachold, Louwrens Hacquebord and Robert Corell, as well as the supporting documents are now available on the IASC History Website.
Printed copies of the publication will be available at the Arctic Science Summit Week (ASSW) 2015 in Toyama, Japan.

New PAGE21 related publication on Nature Geoscience on "Net regional methane sink in High Arctic soils of northeast Greenland"

Christian4 resizedNature Geoscience just newly published a PAGE21 related paper called "Net regional methane sink in High Arctic soils of northeast Greenland" authored by Christian Juncher Jørgensen, Katrine Maria Lund Johansen, Andreas Westergaard-Nielsen and Bo Elberling from the University of Copenhagen.
This paper presents measurements of rates of methane consumption in different vegetation types within the Zackenberg Valley in northeast Greenland over a full growing season.
Based on these measurementthe authors conclude that the ice-free area of northeast Greenland acts as a net sink of atmospheric methane, and suggest that this sink will probably be enhanced under future warmer climatic conditions.
