Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ
