EARTHTIME is an organized, community-based international scientific initiative aimed at sequencing Earth history through the integration of high-precision geochronology and quantitative chronostratigraphy. Our main goal is the development of the geochronological techniques necessary to produce temporal constraints with uncertainties approaching 0.1 percent of the radioisotopic ages.

This portal instance provides a means to upload data into the EARTHTIME atlas.  Please view the tutorial below (NOT COMPLETED YET) to observer how this system operates.
