Seamless Data Distribution System (SDDS) enables a user to view and download many national and international geospatial data layers, such as National Elevation Dataset, National Land Cover Dataset, High Resolution Orthoimagery, and many more. A tutorial is available to guide a user through the download process.

The Virtual Data Center (VDC) software is a comprehensive, open-source digital library system, designed to help curators and researchers face the challenges of sharing and disseminating research data in an increasingly distributed world. The VDC software provides a complete system for the management and dissemination of federated collections of quantitative data.

The "classic" legacy of oceanographic expeditions has been the publication of atlases of the data. For many people these atlases define what the ocean looks like and how it behaves. Now we have WOCE, the largest oceanographic expedition ever mounted. In comparison to earlier efforts, WOCE has a broader scope, greatly increased horizontal and vertical sampling density, improved accuracy and precision and a greater abundance of properties sampled. It is unlikely that such a set of data will be bettered or even repeated soon. We are therefore producing a series of four atlases, concentrating respectively on the hydrography of the Pacific, Indian, Atlantic and Southern Oceans. The volumes each have three main components: Full-depth sections, horizontal maps of properties on density surfaces and depth levels, and property-property plots (see the sample plots section). The vertical sections feature potential temperature, salinity, potential density, neutral density, oxygen, nitrate, phosphate, silicate, CFC-11, d3He, tritium, 14C, 13C, total alkalinity and total carbon dioxide, against depth along the WOCE Hydrographic Programme one-time lines.

ETI's World Biodiversity Database is a continuously growing taxonomic database and information system that aims at documenting all presently known species (about 1.7 million) and to make this important biological information worldwide accessible. Access to this online information system is free of charge for noncommercial use: scientific and educational purposes. All data in the WBD are copyright protected by the authors, artists and other contributors and may not copied or reproduced without approval of ETI and the lawful owners. The WBD is intended to increase understanding and to support a responsible use and to facilitate the management of the earths biodiversity resources. It is built as a joint effort of specialists worldwide who contribute basic taxonomic, ecological and biodiversity data to ETI to make this available in electronic form, both online in the WBD and in subsections on CD-ROMs.

The World Data Center for Paleoclimatology provides data about past climate and environment derived from a diverse range of proxies such as tree rings and ice cores. The proxies are listed by data disciplines. These links provide access to descriptive information and explanatory notes, links to maps, searches, visualizations, and more. The data cover the globe, and while most span the last few millennia, some data sets extend back in time 100 million years. Most of the data are time series of geophysical or biological measurements, and some include reconstructed climate variables such as temperature and precipitation. We have highlighted most of the climate reconstruction data sets in an annotated list. For non-specialists seeking climate data, this list is a useful starting point. Maps and visualizations exist for some data sets. Almost all of the data have been contributed by scientists who have published their results in peer-reviewed literature. The data are used by researchers to understand climate variability, by educators and students and curious individuals to study the past, and by planners and decision-makers who need a better understanding of long-term changes to make policy decisions.

The World Data Center (WDC) system was created to archive and distribute data collected from the observational programs of the 1957-1958 International Geophysical Year. Originally established in the United States, Europe, Russia, and Japan, the WDC system has since expanded to other countries and to new scientific disciplines. The WDC system now includes 52 Centers in 12 countries. Its holdings include a wide range of solar, geophysical, environmental, and human dimensions data. These data cover timescales ranging from seconds to millennia and they provide baseline information for research in many ICSU disciplines, especially for monitoring changes in the geosphere and biospheregradual or sudden, foreseen or unexpected, natural or man-made.

The World-Wide Earthquake Locator aims to provide up-to-date information and detailed dynamic maps of earthquakes across the world within a maximum of 24 hours of their occurence. This web site also includes a database of past earthquakes, an animation of the past month's earthquakes, and statistical earthquake prediction.
