Abstract
The Antarctic geodetic datum constitutes a specialized implementation of the modern geodetic reference system within the extreme polar environment. A high-precision, unified, and dynamic Antarctic geodetic datum serves as critical infrastructure for polar scientific research and engineering safety. This study reviews the composition, current status, and implementation pathways of the Antarctic geodetic datum through four dimensions: coordinate datum, height datum, gravity datum and sounding datum. Preliminary analysis reveals that the development of the Antarctic geodetic datum framework is severely lagging, thereby failing to meet the demands of both scientific expeditions and polar research. To address these challenges, this study proposes an implementation pathway leveraging the 5th International Polar Year (IPY-5) to pioneer regional high-precision geodetic datum in the China’s key research sector covering the area between Amery Ice Shelf and Princess Elizabeth Land, specially highlighting the Prydz Bay–Amery Ice Shelf–Lambert Glacier–Dome A (PANDA) transect, by deploying multi-technique stations and μGal-level superconducting gravimeter networks; and then to integrate multinational observation resources to ultimately establish a high-precision, unified, and dynamic geodetic datum framework. This framework will deliver a spatiotemporal infrastructure for Antarctica to advance the strategic goals of “understanding, protecting, and utilizing Antarctica”.
