The International Polar Year (or IPY) is a collaborative, international effort researching the polar regions. Karl Weyprecht, an Austro-Hungarian naval officer, motivated the endeavor, but died before it first occurred in 1882–1883. Fifty years later (1932–1933) a second IPY occurred. The International Geophysical Year was inspired by the IPY and occurred 75 years after the first IPY (1957–58). The third International Polar Year has ended, having begun in 2007, and continued until 2009. It was sponsored by the International Council for Science (ICSU) the World Meteorological Organization (WMO). The chair of the International Planning Group established within the ICSU for this event was chaired by Professor Chris Rapley and Dr. Robin Bell. The Director of the IPY International Programme Office was (Dr David Carlson ). The latest IPY brought about the most ambitious Arctic climate change research project ever undertaken in Canada, a $150-million (CAD) research program called the Circumpolar Flaw Lead (CFL) System Study. Led by University of Manitoba Professor David Barber, a Canada Research Chair, the project involved more than 300 scientists from 16 countries, including over 40 faculty members, research associates, graduate students, technicians and support staff from the University of Manitoba. Based aboard the research icebreaker, ''CCGS Amundsen'', the CFL project examined the “flaw lead” system, a circumpolar phenomenon created when the central Arctic ice pack moves away from coastal ice, leaving areas of open water. CFL scientists are working closely with northern residents to understand how global climate change is affecting the nature of the flaw lead system in the Northern Hemisphere, and how it is expected to impact the circumpolar Arctic in the coming years. The project involved over-wintering the ''Amundsen'' in the Banks Island flaw lead in the Southern Beaufort Sea, the first time this has ever been done. ''Lessons and Legacies of International Polar Year 2007–2008'', a 2012 report from the National Academies’ Polar Research Board, considers the accomplishments and lessons learned through IPY, finding that overall IPY was an outstanding success.〔http://dels.nas.edu/Report/Lessons-Legacies-International/13321〕 The report found that IPY engaged the public to communicate the relevance of polar research to the entire planet, strengthened connections with the indigenous people of the Arctic, and established new observational networks. Activities at both poles led to scientific discoveries that provided a step change in scientific understanding and helped translate scientific knowledge into policy-relevant information. At a time when the polar regions are undergoing a transformation from an icy wilderness to a new zone for human affairs, these insights could not be more timely or more relevant, the report found.〔http://dels.nas.edu/Materials/Report-In-Brief/4303-IPY〕 The report concluded that the legacies of IPY extend far beyond the scientific results achieved, and valuable lessons learned from the process will guide future endeavors of similar magnitude.〔 ==Motivation== The polar areas have many unique phenomena. Circulatory systems for air and water reach the surface, as do the majority of the Earth's magnetic field lines. Thick glaciers have trapped air and water from ancient times. It is easiest to observe these phenomena near the poles. Unfortunately, the poles are expensive places to visit, because they are distant, cold and deserted; infrastructure is sparse and the terrain is rough in polar regions (often consisting of ice blocks with crevasses between them). International cooperative programs share the costs and maximize the number of coordinated scientific observations. The IPY is the most famous example of such a cooperative program. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「International Polar Year」の詳細全文を読む スポンサード リンク
