The following resources will take you to external links.
- EnvironmentalChemistry.com: Periodic Table of Elements This electronic periodic table provides comprehensive data on elements including scores of properties, element names in many languages and most known nuclides. Click on an element’s symbol or atomic number to view detailed information.
- Chemicool’s Periodic Table of Elements OR WebElements • Alternative electronic periodic tables…
- LBL Nuclear Sciences’s Periodic Table of Isotopes • This chart of nuclides emphasizes isotope information: list of isotopes for each element, half life rates, isomers, etc.
- Chris Heilman’s Pictorial Periodic Table • This electronic periodic table provides alternative views, graphing of properties, etc.
- Jefferson Lab’s Periodic Table for Educators and Students • This electronic periodic table has appeal through use of on-line games, “element crossword puzzles” and other activities. This is one of Jefferson Lab’s educational outreach resources; Jefferson Lab is one of 17 national laboratories funded by the U.S. Department of Energy.
- Petrological Database of the Ocean Floor • This NSF-founded website provides petrological and geochemical data for igneous and metamorphic rocks from mid-ocean ridges, back-arc basins and young seamounts.
- GEOROC • A global geochemical database containing published chemical and isotopic data as well as extensive “metadata” for rocks, minerals and melt/fluid inclusions. It currently covers igneous rocks from island arcs, oceanic islands and large igneous provinces (seamounts, oceanic plateaus, submarine ridges, and oceanic and continental flood basalts). Under the auspices of the Max-Planck-Institut für Chemie.
Maps and Photos
- Trails.com • Commercial vendor who provides digital topo maps and aerial photos, enhanced shaded relief maps (formerly Topozone). They provide a free 14-day trial.
- USGS National Geologic Map Database • Resource for buying paper or digital geologic maps.
- USGS Aerial Photographs for Sale • Resource for buying USGS aerial photos, topo maps, etc.
- USGS Photo Archive • Large library of photos, all in the public domain—none may be copyrighted by users outside the agency. (It’s polite to credit individual photographers and the U.S. Geological Survey when using these.) You can search for just the right photo too. Multiple resolutions (web to print) available.
- Earth Sciences and Maps Library (50 McCone Hall, UCB) • You can find digital maps of all sorts (topo, geological, bioclimate zones) and aerial photographs at UC Berkeley’s friendly Earth Sciences and Maps Library—many available on-line. They have an on-going project to convert all of their paper maps to digital form. The extensive map collection includes many pre-1900 maps as well as maps for locations world-wide throughout the 20th century. For maps unavailable for viewing from outside of the university, you can visit the library itself, and view the map files on one of the Earth Science Library’s computers, and email any specific file to yourself (or alternatively, carry a flash drive with you for copying). Ask for help at the front desk to view CD map collections. In addition, two of their computers have GIS software installed, with access to several databases (uc-affiliate status required to access some databases). The digital collection is always growing, so ask at the Front Desk for updated listings of digitized maps.
