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 ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Projections of Antarctica's sea‐level contribution depend on future changes in surface mass balance (SMB), yet it remains uncertain whether climate change has already impacted SMB on the East Antarctic Plateau, given diverging trends in prior studies.

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Surface Water and Ocean Topography (SWOT) satellite observations are shown to agree well with tide gauge and underwater glider data in the Northeast Pacific. The SWOT mission measures sea surface height in a 120‐km wide swath. It had a 1‐day repeat cycle for 3 months in 2023.

Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.

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.
