The American Geological Institute (AGI) created this website to promote its work dedicated to geoscientific services and outreach. The Information Services provides users with information on data repository systems and the GEoRef database. Students and educators can learn about professional development, conferences, scholarships, and more. The website provides action alerts, discussing key issues...

Based on a talk given by Rick Saltus, this USGS open-file report uses a slideshow format to present work completed and methods used to "edit, document, distribute, and interpret about a million line-kilometers of aeromagnetic data in Alaska." Intermingled with excellent thumbnail graphics, the text describes and explains the accompanying images. Section titles include an Introduction to Magnetic...

Andrew Carnegie was known for his philanthropy, and in 1895 he contributed his vast wealth to creating 22 various organizations that still bear his name. In 1901 he created what became known as the Carnegie Institution for Science with an initial gift of $10 million. Over the past century, the Institution has continued to support a wide range of scientific endeavors, and researchers such as Edwin...

At this website, visitors can discover the studies undertaken by the Department of Geology and Geophysics at Yale University in the six research areas: atmosphere, oceans, and climate dynamics; biogeochemistry, paleoceanography, and paleoclimatology; geochemistry and petrology; paleontology and evolution; the physics of the Earth's interior; and the tectonics and surface processes. The website...

These digitized aeromagnetic datasets from the US Geological Survey show variations in the Earth's magnetic field caused mostly by the distribution of minerals that make up the upper part of the earth's crust. The data may be accessed by clicking on the name of a state or territory. Users can download data for an entire state or obtain files by clicking on state maps showing location plots.

These datasets were prepared by the National Geodetic Survey for the Solid Earth Geophysics Division of the National Geophysical Data Center (NGDC). The data elements are written in ASCII and can be downloaded in compressed format. Geoid height, deflection of the vertical, N/S and E/W components, terrain corrected free-air gravity anomalies, and number of gravity data per cell are available for...

The International Earth Rotation and Reference Systems Service (IERS) was created to provide the astronomical, geodetic, and geophysical communities with standards, geophysical data, earth orientation parameters, and celestial and terrestrial reference systems. After discovering the structure and history of the Service, users can discover the many Product, Technique, and Combination Centres...

Under a grant from the National Park Service's National Center for Preservation Technology, the North American Database of Archaeological Geophysics (NADAG) is developed and maintained by the Center for Advanced Spatial Technologies (CAST) and members of the Department of Anthropology at the University of Arkansas. The Web site primarily targets the general archaeology community, offering a wide...

This website promotes the Russian Academy of Sciences' International Institute of Earthquake Prediction Theory and Mathematical Geophysics's incorporation of modern mathematics with seismology and other geologic sciences. Users can discover the Institute's current and past research in earthquake prediction, seismic risk, structure of the Earth, exploration of mineral deposits and much more. While...

The NASA Astrophysics Data System (ADS) Web site, which is hosted by the Harvard-Smithsonian Center for Astrophysics, is described as a Digital Library for Physics, Astrophysics, and Instrumentation. ADS maintains four bibliographic databases containing more than 3.2 million records that can be searched or browsed by various interfaces including a Journal/ Volume/ Page Service, Table of Contents...
