About IEDA

IEDA2 is a collaborative geoscience data infrastructure that connects EarthChem, LEPR/traceDs, and SESAR. It supports researchers in sharing and accessing sample data following FAIR data principles, with a stated mission of open, reproducible, and transparent science. The site provides entry points to several data systems: the EarthChem Library for archiving and publishing geoscience research data; PetDB for geochemical, geochronological, and petrological data; SESAR² for sample registration and reuse; LEPR/traceDs for experimental phase equilibria data; and a planned Tephra Information Portal. IEDA2 is funded by the US National Science Foundation and hosted at LDEO of Columbia University. Pricing information is not provided. The interface is indicated as English-language, and the site uses cookies for analytics according to its privacy policy.
