The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1999 through June 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations than those publishing fewer papers.

This ranking is by citations per paper (impact), among those institutions that have collected 10,000 or more citations in geosciences during the period. For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top

1 per cent for a field over a given period, based on total citations. For the current version, 435 institutions are listed in the field of geosciences, meaning that a total of 43,500 institutions were surveyed to obtain these results. Of the 435, 104 institutions collected 10,000 or more citations. The ranking by citations per paper (impact) seeks to reveal “heavy-hitters” based on per paper influence, not mere output. US institutions account for 14 of the 20, while the other six are European, including three British institutions. As is plain from the list above, “geosciences” here includes atmospheric research and oceanography as well as geology.
