Polar and Magnetospheric Substorms
168,00 CHF *
ggf. zzgl. Versand

It has become increasingly clear that the magnetosphere becomes intermittently unstable and explosively releases a large amount of energy into the polar upper atmos phere. This particular magnetospheric phenomenon is called the magnetospheric sub storm. It is manifested as an activity or disturbance ofvarious polar upper atmospheric phenomena, such as intense auroral displays and X-ray bursts. Highly active conditions in the polar upper atmosphere result from a successive occurrence of such an element ary activity, the polar substorm, which lasts typically of order one to three hours. The concept of the magnetospheric substorm and its manifestation in the polar upper atmosphere, the polar substorm, has rapidly crystallized during the last few years. We can find a hint of such a concept in the term 'polar elementary storm' introduced by Kristian Birkeland as early as 1908. However, we are greatly indebted to Sydney Chapman, who established the basic foundation of magnetospheric physics and has led researches in this field during the last half century. Indeed, the terms 'polar magnetic substorm' and 'auroral substorm' were first suggested by Sydney Chapman. The concept of the substorm was then soon extended by Neil M. Brice of Cornell University, and Kinsey A. Anderson and his colleagues at the University ofCaliforrlia, Berkeley, who introduced the term 'magnetospheric substorm'. We owe many of these recent developments in magnetospheric physics to the great international enterprise, the International Geophysical Year (IGY) and subse quent international cooperative effort (IGC, IQSY).

Europe has a distinguished history of environmental research and hosts many of the world's leading researchers in the environmental field. Environmental concerns have been on the policy agenda since the European Comunities were created in 1957. The International Geophysical Year (IGY) was launched in the same year as a first attempt to coordinate global measurements of the Earth, the oceans, the atmosphere and the sun. It also pointed out for the first time that carbon dioxide was building up in the atmosphere. The decades since then have witnessed increasing public concern about our environment and the damage being done to it, alongside greater research efforts to increase knowledge and find solutions.

C. T. Russell Originally published in the journal Space Science Reviews, Volume 136, Nos 1–4. DOI: 10. 1007/s11214-008-9344-1 © Springer Science+Business Media B. V. 2008 The Sun-Earth Connection is now an accepted fact. It has a signi cant impact on our daily lives, and its underpinnings are being pursued vigorously with missions such as the Solar TErrestrial RElations Observatory, commonly known as STEREO. This was not always so. It was not until the middle of the nineteenth century that Edward Sabine connected the 11-year geomagnetic cycle with Heinrich Schwabe’s deduction of a like periodicity in the sunspot record. The clincher for many was Richard Carrington’s sighting of a great whi- light are on the Sun, on September 1, 1859, followed by a great geomagnetic storm 18 hours later. But was the Sun-Earth Connection signi cant to terrestrial denizens? Perhaps in 1859 it was not, but a century later it became so. Beginning in the 1930’s, as electrical powergrids grew in size, powercompanies began to realize that they occasionally had power blackouts during periods of intense geomagnetic activity. This correlation did not appear to be suf ciently signi cant to bring to the attention of the public but during the International Geophysical Year (IGY), when geomagnetic activity was being scrutinized intensely, the occurrence of a large North American power blackout during a great magnetic storm was impossible to ignore.

The ‘Year’ That Changed How We View the North This book is about a new theoretical approach that transformed the field of Arctic social studies and about a program called International Polar Year 2007–2008 (IPY) that altered the position of social research within the broader polar science. The concept for IPY was developed in 2003–2005; its vision was for researchers from many nations to work together to gain cro- disciplinary insight into planetary processes, to explore and increase our understanding of the polar regions, the Arctic and Antarctica, and of their roles in the global system. IPY 2007–2008, the fourth program of its kind, followed in the footsteps of its predecessors, the first IPY in 1882–1883, the second IPY in 1932–1933, and the third IPY (later renamed to ‘International Geophysical Year’ or IGY) in 1957–1958. All earlier IPY/IGY have been primarily geophysical initiatives, with their focus on meteorology, atmospheric and geomagnetic observations, and with additional emphasis on glaciology and sea ice circulation. As such, they excluded socio-economic disciplines and polar indigenous people, often deliberately, except for limited ethnographic and natural history collection work conducted by some expeditions of the first IPY. That once dominant vision biased heavily towards geophysics, oceanography, and ice-sheets, left little if any place for people, that is, the social sciences and the humanities, in what has been commonly viewed as the ‘hard-core’ polar research.

Big Ecology

In Big Ecology, David C. Coleman documents his historically fruitful ecological collaborations in the early years of studying large ecosystems in the United States. As Coleman explains, the concept of the ecosystem-a local biological community and its interactions with its environment-has given rise to many institutions and research programs, like the National Science Foundation's program for Long Term Ecological Research. Coleman's insider account of this important and fascinating trend toward big science takes us from the paradigm of collaborative interdisciplinary research, starting with the International Geophysical Year (IGY) of 1957, through the International Biological Program (IBP) of the late 1960s and early 1970s, to the Long-Term Ecological Research (LTER) programs of the 1980s.
