AGU has broken new electronic ground with the first on-line version of the Quadrennial (Quad) Report—the U.S. National Report, 1991–1994. The report, presented at the 21st General Assembly of the International Union of Geodesy and Geophysics (IUGG), presents state-of-the-science reports on geophysics research in the United States. Over 1400 pages long in its printed version, the report is accessible electronically at http://www.agu.org/revgeophys.
The new Quad Report incorporates interdisciplinary and cross-disciplinary articles on topics such as volcanoes and climates, the atmospheric and hydrologic aspects of precipitation; air-sea interaction; and surficial properties. These topics cut across two or more of the six major sections identified for the report: Properties of the Solid Earth; Dynamics of the Solid Earth and Other Planets; Space Sciences; Atmospheric Sciences; Hydrology; and Ocean Sciences.
