The Structure and Development of Polar Research (1981-2007): a Publication-Based Approach.

The present article explores the structure of and recent developments in research activities in the polar regions. Based on a bibliographic study of published papers indexed in the ISI Web of Science during the period 1981-2007, we have analyzed trends in publication, scientific disciplines and subdisciplines, coauthorship, and international collaboration within the field of polar research. We have uncovered several rather striking trends. Scientific output in terms of refereed publications has increased far more rapidly in polar research compared to science in general, quadrupling rather than doubling over the surveyed period. There is a nearly 1:1 ratio between papers covering the Arctic relative to the Antarctic, with the vast majority within either the geosciences (40%) or biology (33%). There has been particularly a steep rise in the number of climate-related papers. The U.S.A. is by far the largest contributor to polar research on both the Arctic and the Antarctic, followed by Canada, the U.K., Germany, Norway, and Russia. The number of coauthored papers has grown markedly, reflecting geopolitical shifts and changing national and international funding priorities during the period. We believe our publication-based survey reveals interesting developments in scientific activities and international cooperation in general, and in polar science strategies and priorities in particular.
