CHRONOS-Climate Cycles is one of six thematic domains that are currently under development for the virtual CHRONOS network. The purpose of this domain is to populate CHRONOS with the key paleoclimate data that have been used to calibrate geologic time, e.g., orbitally forced stratigraphy, and to provide sophisticated means for the geoscience community to investigate new data and methodology. The domain's database will be configured according to frequency scale (orbital, millennial, annual, diurnal) and linked to other CHRONOS databases through at least one independent time control, e.g., geopolarity reversals, radioisotope dates, chemostratigraphy, or biozonation. The domain will host an online laboratory with platform-independent tools for modeling, interpolation, correlation, filtering, tuning, demodulation, and spectral analysis. An educational module with interactive tutorials will explore climate forcing mechanisms (e.g., insolation) and climate system responses. A proof-of-concept demonstration that applies modern chronostratigraphic data and analytical procedures to the legacy SPECMAP dataset is used to illustrate basic geoinformatics elements in CHRONOS-Climate Cycles.
