Covering a much wider field than the usual specialist journals, Earth Science Reviews publishes review articles dealing with all aspects of Earth Sciences, and is an important vehicle for allowing readers to see their particular interest related to the Earth Sciences as a whole. Our readership is more diverse than that of specialist journals: as well as research scientists, also students, government agencies involved in programme support and management and in environmental assessment and control, private industries concerned with planetary resources, and the independent consultant. The journal's vision includes ensuring accessibility for all of these groups. Every review article published will advance existing knowledge and highlight new directions being taken at the forefront of expanding subject areas by synthesis, evaluation and discussion of previously published literature. The value of such articles to the readership is increased with comment and opinion provided by the author from a specific context. Authors may further enhance their article with the addition of supplementary material such as videos, datasets and applications.
