AGU has initiated this supplement as a way to extend Eos coverage in areas of growing importance to geophysical scientists. With this supplement, Eos will be able to cover more information in greater detail -- reaching a worldwide electronic audience.

This Eos electronic supplement provides more information about subjects that appear in the printed version of Eos. The supplement is a fully integrated part of Eos and is fully archived and referenceable. The high peer-review and editorial standards for which Eos is known also apply to the material in the supplement. Brief material in the printed component of Eos will reference the longer, more detailed information on the same topic in the supplement.
