A case study comparing approaches to mask satellite-derived bathymetry

Discover Geoscience
Abstract Satellite-derived bathymetry (SDB) is a cost-effective method for estimating water depth in inland and coastal waters, but is only applicable to optically shallow water (OSW). Determining the appropriate extent of SDB maps and the depth threshold for accurate SDB model predictions has therefore been a challenge for practical ...

Coral δ13C Reveals Little Ice Age Dimming of Tropical Surface Shortwave Radiation Not Captured by Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Tropical low‐cloud feedback is the largest source of uncertainty in climate sensitivity, yet multi‐century records of surface shortwave radiation are scarce. We calibrate Porites coral δ13C against satellite photosynthetically available radiation (PAR) and reconstruct monthly PAR for the northern South China Sea during the Medieval Climate ...

A fully satellite-driven workflow for hydrodynamic modeling in data-scarce coastal systems: integrating ICESat-2, Sentinel-2, SWOT and reanalysis models

Frontiers in Remote Sensing
Hydrodynamic models in coastal and estuarine systems are typically constrained by sparse bathymetry, boundary, and validation data, especially in regions where field campaigns are costly or impractical.

Topographic Anchoring and the “Silent Period” of Deep‐Water Polynyas in the 90°W–90°E Antarctic Sector

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Antarctic deep‐water polynyas act as critical windows driving deep ocean ventilation, exerting profound impacts on the global thermohaline circulation and biogeochemical cycles. Utilizing high‐resolution satellite remote sensing and ocean reanalysis data from 2003 to 2022, this study identified eight recurring deep‐water polynyas within the ...

Characterizing Landslide‐Induced Floods Using the SWOT Mission: A Case Study on the Chilcotin River, Canada

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Monitoring small rivers during extreme events is challenging, especially in remote areas. This study assesses the accuracy of the Surface Water and Ocean Topography (SWOT) mission in characterizing an extreme hydrological event on a narrow river (∼60 m wide), using a landslide‐induced flood on the Chilcotin River (Canada) as a case study.

Long‐Period Seismic Waves From Seawater Disturbances During the 2018 Anak Krakatau Volcanic Island Collapse

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Landslides often generate long‐period seismic waves that propagate over large distances. During volcanic island collapses and their intrusion into seawater, seismic signals of >1 min periods are widely observed. The physical sources of these signals remain poorly understood due to complex landslide‐water interactions. In this paper, we perform

GRDL: A New Global Reservoir Area‐Storage‐Depth Data Set Derived Through Deep Learning‐Based Bathymetry Reconstruction

Water Resources Research
Reservoirs play a critical role in the global water cycle by regulating the flow of water from the environment into human systems. Accurate estimation of the area‐storage‐depth relationships for global reservoirs is essential for effective hydrological ...
