Abstract:

The Digital Twins of Geosciences (DTG) is a new generation of virtual systems with geoscience at its core and computer technology as its support. As a frontier of international scientific and technological innovation, the DTG aims to use information systems and artificial intelligence technology to serve real scenarios in the geoscience field. Over the past 10 years, our team has carried out interdisciplinary development and application in the field of digital twins, and has made some progress in application scenarios such as marine engineering and Earth's evolution:

(1) We have developed a marine environment DTG for the protection of Hong Kong-Zhuhai-Macao Bridge (HZMB) Island Tunnel project. By organizing, managing, and visualizing real-time monitoring data of the marine physical environment，we have achieved real-time analysis and information decision-making of wind, wave, and current data, providing precise marine environmental forecast information for the construction of the HZMB.

(2) We have developed a geological digital twin platform, which is currently being developed within the Deep-time Digital Earth (DDE) Big Science Program. This system has initially achieved visualization and analysis of multidimensional geospatial-temporal data such as dynamic simulation of paleo tectonic plates and custom drawing of geological profiles, with the expectation of aiding geoscientists worldwide by coupling data, knowledge, models, and computing power, providing scientific inspiration for geoscientists, and promoting data-driven Earth science research.
