EarthRef: Website for Physical and Chemical Earth References
The EarthRef web site contains several online databases, downloadable modeling tools, and more. The databases include GERM (Geochemical Earth Reference Model), the EarthRef Digital Archive, the Seamount Catalog, and Partition Coefficients. A Geophysical Reference Earth Model (REM) is currently under construction. The GERM database contains summary data on the geochemistry of all reservoirs in the Earth and solar system. It includes only peer-reviewed data and is searchable by reservoir, element, and reference. The EarthRef Digital Archive contains any type of digital data object associated with the Earth Sciences. Data objects may be part of non-published Earth Sciences projects ranging from data tables to diagrams to reports to geological maps to videos. The Seamount Catalog includes a searchable database of maps and morphological data sheets, and a library of gridded bathymetry files along with their original multibeam data. The Partition Coefficient database contains Kd (partition coefficient) data for all types of rocks and minerals and for every element. Both experimental and empirical data are included in this extensive compilation.
