Research Progress in Surface and Marine Gravimetry

Gravity field is the most basic physical field generated by the material properties of the Earth system. It reflects the spatial distribution, movement and change of materials determined by the interaction and dynamic process inside the Earth. Over the years, a variety of technical means have been used to detect the Earth’s gravity field and supported numerous studies on the global change, resource detection, geological structure movement, water resources change and other related fields of research. Here is part of the progress in surface and marine gravimetry obtained by Chinese geodesy scientists from 2019 to 2023 from the following aspects, including: ① Continuous gravity network in Chinese mainland; ② Application of superconducting gravity measurement; ③ Network adjustment for continental-scale gravity survey campaign and data quality control; ④ Regional time-variable gravity field and its application; ⑤ Research progress on novel technologies for gravity inversion; ⑥ Research progress on marine gravity field determination; ⑦ Application research on marine gravity field.
