Impact of Slopes on ICESat-2 Elevation Accuracy Along the CHINARE Route in East Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
As the follow-on study to the assessment of ICESat-2 ice surface elevations, we assessed how they are influenced by the surface slopes, which are derived from the ICESat-2 elevations of the received photons and available in the land-ice surface heights ...

Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

A Scalable, Cloud‐Based Workflow for Spectrally‐Attributed ICESat‐2 Bathymetry With Application to Benthic Habitat Mapping Using Deep Learning

Earth and Space Science
Since the 2018 launch of NASA's ICESat‐2 satellite, numerous studies have documented the bathymetric measurement capabilities of the space‐based laser altimeter.

Runoff Capture by Sea Level Rise Alters the Area, Geometry, and Quantity of Coastal Catchments

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Coastal catchments, which drain directly to the sea, mediate material fluxes across the land‐sea interface and support species diversity and economic activity in coastal zones. Here, we explore the evolution of coastal catchment divides at the local to global scale from 2000 to 2120 under multiple SLR scenarios using state‐of‐the‐art digital ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

ICESat‐2 Pointing Calibration and Geolocation Performance

Earth and Space Science, 2021
ICESat‐2 science requirements are dependent on the accurate real‐time pointing control (i.e., geolocation control) and postprocessed geolocation knowledge of the laser altimeter surface returns. Prelaunch pointing alignment errors and postlaunch pointing

Quantifying river morphological changes using multi‐satellite observations and in situ measurements

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.

Sensitivity of Flood Extent and Population Exposure to Variations in Bathymetry Across a Shallow Continental Shelf Lagoon

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Bathymetry is a critical input to storm surge models on coastlines fronted by lagoon systems, yet few studies explore how variations in bathymetry influence flood impacts, flooded extent, and exposed population across these globally widespread morphologies.

Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...
