CIRDLES is creating cyber infrastructure for geochronology in an interdisciplinary collaboration among our software engineers and geochemists from two NSF-supported initiatives, EARTHTIME and EarthChem. The EARTHTIME initiative is a community-supported network of geologists and geochemists focused on providing the tools necessary for high-precision sequencing of earth history using an integration of radioisotopic dating and stratigraphy. The EarthChem project is designing data repositories for all geochemical data, including radioisotopic geochronological data.
CIRDLES is designing and building a novel and exemplar end-to-end data processing system for uranium-lead geochronological data that links data production to data archiving. This system is the template for future efforts to process all geochronological data such as other radioisotopic systems involving 40Ar/39Ar, U-Th-He, and Lu-Hf. One novel and important aspect of the project is to integrate pedagogical and learning aids into the software products we develop. For example, the data reduction algorithms and the equations for the propagation of uncertainty will have interactive graphical interfaces to provide transparency and to enhance understanding.
