The study of gravity throughout history has shed light on a wide range of scientific disciplines, from fundamental physics like Einstein's theory of gravity to planetary geodesy, that influence many aspects of human life today.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Tropical deforestation driven by agricultural expansion to meet growing food demand poses a rising threat to the global carbon cycle. While previous studies quantified agriculture‐related carbon losses, the role of cropland expansion remains poorly resolved, partly because widely used agricultural driver data sets are too coarse to detect fine‐

Observation of Yanai Wave Excitation by Tropical Instability Waves in the Equatorial Pacific
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Yanai waves are observed in the central equatorial Pacific at 436–864 m depth, below the Equatorial Undercurrent. Applying maximum likelihood estimation to shipboard ADCP measurements enables identification of Yanai wave signals from irregularly sampled observations.

Does Polar Warming Asymmetry Exist in Bathy‐Planet Experiments?
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Ocean bathymetry and continental geometry shape ocean circulation, but whether these geographic constraints can sustain polar warming asymmetry in a fully coupled climate system remains unclear. Here we construct a fully coupled “bathy‐planet” configuration (BATHY), in which continental topography is removed and most land surfaces are replaced

Source‐Unbiased Subsurface Monitoring With Seismic Noise
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study addresses a key limitation of seismic noise interferometry for subsurface monitoring: the impact of non‐stationary sources on seismic velocity change estimates. Conventional methods rely on time‐period references, which can inherit source‐related effects when source conditions vary, biasing the estimated velocity changes.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Large intraplate earthquakes are paradoxical because they occur far from active plate boundaries. Northern Hainan Island (South China) hosts the 1605 Qiongbei M7.5 earthquake within a volcanic province linked to the Hainan mantle plume. New shear‐wave velocity images reveal two shallow low‐velocity zones extending to ∼10 km depth: a stronger ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...
