Deriving Intertidal Topography From SWOT Data and Sentinel‐2 Data
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract The Surface Water and Ocean Topography (SWOT) mission, initially designed to observe oceans and inland waters, proves valuable for mapping intertidal flat topography. This study presents a fusion method that integrates freely available SWOT interferometric altimetry data with Sentinel‐2 imagery.

Earth and Space Science, Volume 12, Issue 10, October 2025.Abstract An accurate geoid has important consequences for many fields such as engineering applications, underground resource exploration, geophysical surveys, etc. Its precise determination relies on two key data sets: gravity measurements and high‐resolution elevation data, both of which are critical for achieving reliable results.

Remote Sensing, 2020 Almost half of the Earth’s land is covered by large river basins. Temporal variations of hydrological masses induce time-varying gravitational potential and temporal mass loading that deforms the Earth’s surface. These phenomena cause temporal variations

Calving Mechanisms Inferred From Observations of Surface Depressions at Helheim Glacier, Greenland
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.Abstract Dynamical changes at the termini of tidewater glaciers may trigger sustained acceleration, thinning, and retreat, increasing a glacier's contribution to sea level rise. However, processes at the ice‐ocean interface occur across a range of spatial (cm to km) and temporal (minutes to years) scales, making these processes difficult to capture ...
