Debt Limit Standoff: 10 Things to Watch. Republicans and Democrats on Capitol Hill are strategizing for what is expected to be a bruising debate on raising the nation's debt limit and reining in government spending. The Obama administration has set an early-July deadline for lifting the $14.3 trillion debt ceiling, a move that congressional leaders agree must be done. The Hill 

Can Siberian Hot Springs Reveal Ancient Ecology? Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth's early atmosphere, according to a theory that U Chicago researcher Albert Colman is testing in the scalding hot springs of a volcanic crater in Siberia.

Seventh Ministerial Meeting of the Arctic Council, May 12.  The Arctic Council will host this meeting in Nuuk, Greenland.  The meeting will consider "The Changing Arctic: Challenges and Opportunities for the Arctic Council;" the Nuuk Declaration; the Arctic Council Search and Rescue Agreement; and hand over chairmanship to Sweden.

6th International Conference on Arctic Margins, May 31-June 3.  The International Conference on Arctic Margins was founded by the Department of Interior and what was formerly called the Minerals Management Service. Topics include: hydrocarbon potential and gas hydrates; science issues relating to UNCLOS Article 76; geodynamic significance of Arctic magmatism; vertical motions in the Arctic, tectonic, and glacial; geology and palaeogeography of the Arctic continental margins; evolution of the Arctic Ocean basins, including plate reconstructions, magmatism, and sedimentology; modern Arctic environments, including geological, climatic, and oceanographic processes; recent advances in Arctic research technology.

The Arctic Imperative, June 19-21.  The Alaska Dispatch, Institute of the North, Aspen Institute, and Commonwealth North will host a summit on policy, infrastructure investment and economic opportunities in Alaska as the Northeast and Northwest passages become navigable.

4th Symposium on the Impacts of an Ice-Diminishing Arctic on Naval and Maritime Operations, June 20-21, 2011.  The symposium is co-hosted by the U.S. National Ice Center (NIC) and the U.S. Arctic Research Commission. This symposium addresses present and future impacts of rapid changes in Arctic Ocean sea ice cover on a wide range of maritime operations. The forum, the fourth in a series, is a key opportunity for federal entities to discuss their response to changes in both the Arctic environment and associated policies. Registration is now open.

Holocene Glacier Variability from the Tropics to the Poles, July 20-27, 2011. Glaciers respond sensitively to climate change. Recent (Holocene) glacier fluctuations are a valuable proxy for terrestrial interglacial paleoclimate conditions. A main challenge for interpreting paleoclimate from past mountain glacier extents is distinguishing local and regional patterns from global signals. Reconstructing Holocene glacier extents involves many disciplines including terrestrial and marine geology, geochronology and glaciology. Organizers hope to facilitate an inter-hemispheric comparison of glacier records including locations in the Tropics, European Alps, American Cordillera, Southern Alps of New Zealand, Himalaya and Polar Regions and to identify future research questions and directions.

7th Congress of the International Arctic Social Sciences, June 22-26, 2011 

Congress of the Arctic Social Sciences is held every 3 years. 

13th Arctic Ungulates Conference (AUC), August 22-26, 2011. The theme of the conference will be "Challenges of Managing Northern Ungulates." The theme addresses the difficulties of managing ungulate populations that are faced with the unpredictable effects of climate change and an ever-increasing human presence on the land. The conference will also focus on the challenges associated with developing recovery actions for declining caribou and reindeer populations that are an integral part of Aboriginal cultures and ways of life. 
 
9th International Symposium on Permafrost Engineering, September 3-7, 2011. The Melnikov Permafrost Institute (Yakutsk, Russia), the Institute of Northern Mining (Yakutsk, Russia), the Cold and Arid Regions Engineering and Environmental Research Institute (Lanzhou, China), and the Heilongjiang Institute of Cold Region  Engineering (Harbin, China) will host the Ninth International Symposium on  Permafrost Engineering to be held in Mirny, Yakutia. The aim of the Symposium is to provide a forum for discussion of permafrost engineering issues, as well as for exchange of practical experience in construction and maintenance of engineering structures on frozen ground. For additional information, please contact Lilia Prokopieva. 

4th International Sea Duck Conference, September 12-16. The conference is held to provide researchers and managers with opportunities to share information, research, and conduct workshops.

Lowell Wakefield International Fisheries Symposium, September 14-17, 2011.The 27th Lowell Wakefield International Fisheries Symposium, entitled "Fishing People of the North: Cultures, Economies, and Management Responding to Change," will be held in Anchorage, Alaska. This international symposium will provide a forum for scholars, fishery managers, fishing families, and others to explore the human dimensions of fishery systems and growing need to include social science research in policy processes. The conference is part of the University of Alaska Fairbanks Sea Grant program.    

Advanced Workshop on Oil Spills In Sea Ice: Past, Present and Future

A technical workshop, organized by Dr. Peter Wadhams, on the physical problems associated with oil spills and blowouts in sea ice will be held at the Istituto Geografico Polare "Silvio Zavatti," Fermo, Italy, on September 20-23, 2011. Scientists, engineers and policy makers are invited to address the questions of how oil is emitted from a blowout or spill, how the oil and gas are incorporated in the under-ice surface, how the oil layer evolves, how the oil is transported by the ice, and how and where eventual release occurs. The aim is to incorporate the experience of those scientists who worked in this field in the 1970s-1990s, when large-scale field experiments involving oil release were possible, and to relate this to the needs of present researchers who are seeking solutions to the problem of a sustainable Arctic oil spill management system. Notably, the workshop will be attended by the oil spill work package of the EU ACCESS project (Arctic Climate Change and its Effect on Economic Systems). Registration forms are available here.
