China advances geological and marine exploration technologies

Lightweight Airborne Gravimeter

The GIPS-1A is a compact airborne gravimeter that can be mounted on various platforms, including unmanned aircraft, survey ships and submersibles. It measures local gravity anomalies in motion, supporting fields such as resource exploration, geodesy, geophysics, marine science, defense and space research. Sharing a similar design with the internationally recognized AIRGrav, the GIPS-1A stands out for its small size, light weight, high precision, strong environmental adaptability and reliability.

Ground-airborne Transient Electromagnetic System

Developed to tackle challenges in rough terrains, the ground-airborne transient electromagnetic system integrates unmanned and intelligent technologies. Drones are used for data collection, removing the constraints of difficult environments such as deserts, forests and wetlands. The system has shown outstanding performance in mineral exploration and geological hazard surveys in complex regions, including Guizhou province and the Xinjiang Uygur autonomous region. Developers are working with industry partners to advance commercialization and expand its applications.

Multiband Intelligent Ocean-bottom Seismometer

Developed by the Guangzhou Marine Geological Survey in 2017, the multiband intelligent ocean-bottom seismometer is a key tool for marine geophysical research. Deployed on the seafloor, it records seismic wave signals to create detailed images of subsea geological structures. The device is widely used in marine resource exploration, geophysical studies, earthquake monitoring, microseismic observation and subsea carbon sequestration projects.

Field Rapid Analysis and Testing Platform

The field rapid analysis and testing platform enables on-site testing for geological surveys, mineral exploration and environmental monitoring. Mounted on a vehicle, it can analyze 69 major and trace elements using portable hyperspectral instruments and other devices. Delivering lab-quality results in the field, the platform offers environmentally friendly and efficient analysis. Since 2023, it has been deployed in 12 projects across a variety of terrains, including mountains, plateaus, grasslands, deserts and tropical rainforests, significantly shortening the time needed for mineral exploration.

Deep-ocean Drilling Vessel Meng Xiang

The Meng Xiang, China's first domestically designed and built deep-ocean drilling vessel, marks a major step forward in oceanic research. Measuring 179.8 meters long and 32.8 meters wide, it has a displacement of 42,600 metric tons and a range of 15,000 nautical miles. Capable of sustaining operations for up to 120 days and accommodating 180 crew members, the vessel can withstand typhoons up to level 16, with wind speeds at around 200 km/h. Equipped with an advanced hydraulic lifting rig that can drill as deep as 11,000 meters, the Meng Xiang integrates oceanic scientific drilling, deep-sea oil and gas exploration, and gas hydrate testing — supporting China's exploration of the Earth's deep structures.
