Taxonomy of IMT Interference on Aeronautical Systems

Radio Science, Volume 61, Issue 4, April 2026.
Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...

Multi‐Sensor Airborne Remote Sensing for Calibrating Hydrodynamic and Sediment Transport Models in Coastal Louisiana Wetlands (Atchafalaya–Terrebonne)

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract This study integrates high resolution remote sensing data from NASA's Delta‐X mission with a process based hydrodynamic and sediment transport model to improve predictions of water levels and suspended sediment dynamics in the Mississippi River Delta, in coastal Louisiana, USA, focusing on Atchafalaya and Terrebonne basins.

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 ...

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.

Seasons and seasonality in lakes: A synthesis amid global change

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Seasonality in environmental conditions plays a fundamental role in shaping lake ecosystems. However, patterns of seasonality vary worldwide, and these patterns are shifting over time amid global change. Thus, it is increasingly important to evaluate how seasons and seasonality are represented in lake ecosystem research.

Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Near‐Inertial Wave Trapping Inside a Fine‐Scale Anticyclonic Eddy During the BioSWOT‐Med 2023 Cruise: Turbulence and Energy Flux

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,

Antarctic Grounding Line Mapping From CryoSat‐2 Radar Altimetry [PDF]

Geophysical Research Letters, 2017
AbstractWe present a new technique for mapping the grounding line of Antarctic ice shelves using a combination of CryoSat‐2 standard and swath elevation data. Our method is based on detecting the tidal signal in pseudo crossovers and is tested on the Siple Coast region of West Antarctica.

Ice Sheet Elevation Change in West Antarctica From Ka‐Band Satellite Radar Altimetry

Geophysical Research Letters, 2019
Satellite altimetry has been used to track changes in ice sheet elevation using a series of Ku‐band radars in orbit since the late 1970s. Here, we produce an assessment of higher‐frequency Ka‐band satellite radar altimetry for the same purpose, using ...

Satellite radar altimetry aids seafloor mapping

Eos, Transactions American Geophysical Union, 1991
The connection between gravity and oceanic water depth was realized more than a century ago. In 1859, J. H. Pratt derived a formula relating anomalous vertical deflection and sea level height on the coast of India to the depth of the adjacent Indian Ocean.
