StreamChemDB aims to provide one-stop access to long-term stream chemistry data records and associated metadata for two national networks:  the U.S. Forest Service Experimental Forests and Range (EFR) system and the National Science Foundation’s Long-term Ecological Research (LTER) sites.  This proposed database builds on former LTER-EFR cyberinfrastructure projects ClimDB and HydroDB (, which similarly provide one-stop access to climate and hydrology data across 45 EFRs and LTERs.  The project combines data sets that are currently unavailable on the web or are only accessible on disparate web sites in a variety of formats.
