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 ...

Optimal Configuration of Omega-Kappa FF-SAR Processing for Specular and Non-Specular Targets in Altimetric Data: The Sentinel-6 Michael Freilich Study Case

Remote Sensing
In this study, the full-focusing (FF) algorithm is reviewed with the objective of optimizing it for processing data from different types of surfaces probed in altimetry.

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Estimating the Impact of Socioeconomic Drivers on Land Degradation in Italy via Spatio‐Temporal Additive Expectile Regression

Environmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT Climate changes, soil degradation, and desertification increasingly threaten the entire territory of Italy due to the complex interplay between natural processes and anthropogenic forces. Motivated by this pressing issue, this paper investigates how land‐use and socioeconomic drivers have shaped desertification dynamics across Italian ...

Global Bathymetry and Topography at 15 Arc Sec: SRTM15+

Earth and Space Science, 2019
An updated global bathymetry and topography grid is presented using a spatial sampling interval of 15 arc sec. The bathymetry is produced using a combination of shipboard soundings and depths predicted using satellite altimetry.

Time-domain Statistics of the Electromagnetic Bias in GNSS-Reflectometry

Remote Sensing, 2015
Global Navigation Satellite Systems-Reflectometry (GNSS-R) is an emerging remote sensing technique that uses navigation signals reflected on the Earth’s surface as sources of opportunity for scatterometry and altimetry.

Measuring Ganymede’s Librations with Laser Altimetry [PDF]

Geosciences, 2019
Jupiter’s moon Ganymede might be in possession of a subsurface ocean located between two ice layers. However, from Galileo data it is not possible to unambiguously infer the thickness and densities of the individual layers. The upcoming icy satellite mission JUICE (JUpiter ICy moons Explorer) will have the possibility to perform more detailed ...

Extraction of tidal channel networks from airborne scanning laser altimetry and aerial photography [PDF]

, 2003
The study of the morphodynamics of tidal channel networks is important because of their role in tidal propagation and the evolution of salt-marshes and tidal flats. Channel dimensions range from tens of metres wide and metres deep near the low water mark

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.

Correction of Interferometric and Vegetation Biases in the SRTMGL1 Spaceborne DEM with Hydrological Conditioning towards Improved Hydrodynamics Modeling in the Amazon Basin

Remote Sensing, 2015
In the Amazon basin, the recently released SRTM Global 1 arc-second (SRTMGL1) remains the best topographic information for hydrological and hydrodynamic modeling purposes.
