The 7th Arctic Frontiers conference addresses the contemporary and emerging political issues for the changing Arctic. How do states in and outside the region prepare strategically for the new Arctic reality? How does the global security architecture impact on security in the Arctic? How important is Arctic oil and gas production for global demand and the energy security of various states? How will traditional businesses interact with new industry, and if and how will profits from industrial activities benefit the people living in the High North.
Change is the keyword which best describes the future of the Arctic. A warming Arctic with less ice creates economic opportunities but it also presents new challenges for Arctic stakeholders. Join us at this year's Arctic Frontiers Conference to engage with the experts and be ready to meet the challenges that lie ahead for the Arctic.

The December issue also contains an Arctic Profile of Ernest William Hawkes, written by Barnett Richling; five book reviews; a Letter to the Editor; and two obituaries, one for Geoffrey Hattersley-Smith, and the other for Richard George Bolney Brown.
The InfoNorth section of the December issue contains two essays written by the AINA 2012 scholarship winners. N. Jane Harms, the recipient of the Jennifer Robinson Memorial Scholarship, provided an update on her study of avian cholera among common eiders in the eastern Canadian
Arctic. Ann Balasubramaniam, the 2012 recipient of the Lorraine Allison Scholarship, presented her research on hydro-limnological relationships in thermokarst lakes of the Old Crow Flats, Yukon.

A committee of experts will plan the workshop to explore opportunities for using remote sensing to advance our understanding of permafrost status and trends and the impacts of permafrost change, especially on ecosystems and the carbon cycle in the high latitudes. The workshop discussions will be designed to encourage attendees to articulate gaps in current understanding and potential opportunities to harness remote sensing techniques to better understand permafrost, permafrost change, and implications for ecosystems in permafrost areas. The committee will write a report that summarizes the workshop discussions.
The committee of 8-9 members will meet numerous times by conference call to plan the workshop structure, identify appropriate speakers and attendees, and develop background materials for attendees. Committee members will lead the workshop and serve as session facilitators. The committee will remain for an extra day after the public workshop to summarize the discussions and begin preparing the workshop report.
The committee will need expertise in a range of areas: permafrost, high latitude ecosystems, remote sensing technologies (e.g., LIDAR, hyperspectral, optical, radar, InSAR, thermal infrared, airborne resistivity), climate change, hydrology, vegetation, geomorphology, and snow science. To submit a nomination, please email Rob Greenway (firstname.lastname@example.org) with the person's name, affiliation, contact information, area of expertise, and a brief statement on why the person is relevant to the study topic.
The main topics of the conference will be:
- Mountain and volcanic permafrost
- Subsea permafrost
- Subglacial permafrost
- Permafrost processes
- Permafrost modelling and mapping
- Constructions on frozen ground
- Permafrost microbiology and astrobiology
- Permafrost dating and paleoreconstructions
- Permafrost-affected soils and biosystems
- Permafrost biogeochemistry
- Permafrost hydrology and hydrogeology
- Permafrost long-term monitoring
- Constructions on frozen ground
If you are interested in being a chair of the section, or have an idea to add an extra one - they are open for disscussion.
Several roundtables will be organized: Antarctic permafrost and soils (ANPAS), TSP, CALM, Antarctic and mountain permafrost, palaeoreconstructions, PYRN.
The deadline for Registration is April 15, 2013
The congress language is English.
Detailed information on the Conference and forms for registration and abstract submission will be available at www.cryosol.ru/publ/kalendar_konferencij/earth_cryology_xxi_century/1-1-0-5 after January 10, 2013.

On December 6 in Doha, as the COP 18 climate change negotiations switched gears for the finale, the Swedish Chairmanship of the Arctic Council arranged a side event on climate change in the Arctic. The event was held against the background of the rapid and ominous development lately in the Arctic, in particular the past summer's sea ice melt. The event was well attended and a strong panel including Martin Lidegaard, climate and energy minister of Denmark, Jens Fredriksen, Minister for housing, infrastructure and transport from Greenland, and Lena Ek, Swedish Minister for the Environment, contributed to a lively discussion.
Measurements of equivalent black carbon (EBC), calculated from aethalometer measurements of light attenuation, were carried out in July 2011 at Ny-Ålesund in the Arctic. Highly elevated EBC concentrations were observed within the settlement of Ny-Ålesund, with a median value of 17 ng m−3, which was about two times the background level. Results from the ensemble empirical mode decomposition method suggested that about 60–80% of atmospheric EBC concentrations at Ny-Ålesund were from local emissions, while only 20–40% arrived via atmospheric transport. The estimated average local emission rate was 8.1 g h−1, with an uncertainty of approximately a factor of two. The pollution plume was confined to 10 km downwind of the settlement, with the total EBC deposition estimated to be 6.4–44 ng m−2 h−1. This may affect snow black carbon (BC) concentrations in nearby glaciated areas. The efficiencies of the long-range transport were estimated based on cluster analysis and potential precipitation contribution function, and the results implied that transport from western Europe is more efficient than from central Russia, on account of relatively rapid transport from western Europe and infrequent precipitation along this route. However, there was no correlation between air mass back-trajectories and EBC concentrations, suggesting that the contribution of long-range transport to EBC measured in Ny-Ålesund might be not significant in this season.
Keywords: Equivalent black carbon; Ny-Ålesund; human influences; transport efficiency.
