Progress in the information-based construction of marine geology

As marine geological surveys continue to deepen, there is an urgent need to develop new-generation information technologies to accelerate the transformation of marine geological survey pattern. In recent years, the digital marine geological project has developed a comprehensive framework of trinity that integrates geological cloud, big data, and intellectualization based on the practical needs of marine geological surveys. Furthermore, the planning of three major systems, i.e., the support, core, and key systems, has been proposed for marine geological informatization. These suggest significant progress in the construction of marine geological cloud platform, marine geological big data infrastructure, and intelligent applications in marine geology. The progress also includes the building of professional marine geological nodes and network systems, the formation of a national marine geological data resource system, and the advancement in the intelligent application of marine geological operations. Information-based construction have played a full role in promoting the transformation and upgrading of geological surveys, while also serving natural resources management.
