Geophysics and Gravity Measurements

Geophysics and Gravity Measurements is a research topic within Oceanography. Science Explorer counts 54k research works in it since 1950. 10.4% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the global variability and change in sea level, with an emphasis on utilizing GRACE and other satellite measurements to understand factors such as groundwater depletion, polar ice sheet mass loss, and the impact of climate change. The papers also explore the use of hydrological and geodetic modeling to assess land water storage and its contribution to sea level rise.
