At Deep-time Digital Earth (DDE), we are on a mission to bring together billions of years of our planet's history through a groundbreaking Big Science program. By harnessing massive geological and allied earth sciences datasets and innovative technologies, our global collaboration aims to create an interconnected digital profile of Earth's past that can analyse and attempt to predict the future. We seek to transform the field of Earth science by making data about our planet's geological evolution accessible to scientists, students and the public. Researchers worldwide will be empowered to gain extraordinary new insights into long-term climate shifts, evolutionary turning points, and natural resources to better understand the world we live in today and the future world. Join us in this bold quest to unveil the epic story of Earth's origins, environments, and life, across immense stretches of time. With deeper knowledge of where we have been as a civilization, we can chart a course for where we are yet to go.
