Field of Geosciences - August 2009

This map of Geosciences is based on research-front data for the six-year period ending in February 2009. The map shows the major fields of Geosciences linked together in a network based on the same principles as our research-front maps showing highly cited papers. In the case of a field map, we first identify all research fronts in Essential Science IndicatorsSM from Thomson Reuters which were assigned to the Geosciences category based on journal. Then the linkage between fronts is computed based on how often they are co-cited—that is, the frequency that current papers cite the two fronts jointly. A clustering process then groups fronts into larger aggregates. Thus, each circle in the map represents a group, or cluster, of research fronts on a broad topic in Geosciences. Hot fields containing concentrations of recent highly cited papers are shown in yellow. Annotations have been added to this map which represent the main research themes. These appear as labels attached to specific regions on the maps. Additional information about Research Fronts.
