Modulation of Eddy Kinetic Energy by Seasonal Extension of the Eastern Weddell Gyre

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Active eddies in the eastern Weddell Gyre (WG) facilitate water mass exchange between the WG and warmer Antarctic Circumpolar Current, driving warm inflow into the WG. Using observations and data‐assimilating model output, the impact of seasonal extension of the eastern WG on the local eddy kinetic energy (EKE) field was investigated.

Detection and Characterization of Ship Targets Using CryoSat-2 Altimeter Waveforms [PDF]

Remote Sensing, 2016
This article describes an investigation of the new possibilities offered by SAR altimetry compared with conventional altimetry in the detection and characterization of non-ocean targets. We explore the capabilities of the first SAR altimeter installed on the European Space Agency satellite CryoSat-2 for the detection and characterization of ships.

Variability of Arctic sea ice thickness and volume from CryoSat-2 [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
We present our estimates of the thickness and volume of the Arctic Ocean ice cover from CryoSat-2 data acquired between October 2010 and May 2014. Average ice thickness and draft differences are within 0.16 m of measurements from other sources (moorings, submarine, electromagnetic sensors, IceBridge).

Surface Water and Ocean Topography (SWOT) Observations Unveil Small Mesoscale Variability on the East Greenland Shelf

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract In the Arctic, mesoscale ocean processes occur at much smaller scales (5–60 km) than at mid‐latitudes (50–100 km), and conventional altimetry thus only resolves the largest of these signals. Here we show how high‐resolution measurements from the Surface Water and Ocean Topography (SWOT) satellite can be used in conjunction with conventional ...

THE RESEARCH ON ELEVATION CHANGE OF ANTARCTIC ICE SHEET BASED ON CRYOSAT-2 ALIMETER [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
In this paper, the Cryosat-2 altimeter data distributed by the ESA, and these data are processed to extract the information of the elevation change of the Antarctic ice sheet from 2010 to 2017.

Slope Correction for Ocean SAR Altimetry

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Since the 2010 launch of Cryosat‐2, a new generation of altimeters, referred to as SAR altimetry, has emerged and partially replaced the previous conventional altimeters known as Low Resolution Mode (LRM) altimetry. A surface slope correction has been previously developed for LRM altimetry.

Greenland Ice Sheet Elevation Change From CryoSat‐2 and ICESat‐2

Geophysical Research Letters
Although fluctuations in ice sheet surface mass balance lead to seasonal and interannual elevation changes, it is unclear if they are resolved differently by radar and laser satellite altimeters.

Snow depth estimation on leadless landfast ice using Cryo2Ice satellite observations [PDF]

The Cryosphere
Observations of snow on Arctic Sea ice are vitally important for sea ice thickness estimation, bio-physical processes, and human activities. While previous studies have combined CryoSat-2- and ICESat-2-derived freeboards to estimate snow depth over ...

A Novel Method for Reservoir Outflow Simulation Based on Spearman Rank Correlation Between Satellite‐Derived Water Elevations and Model‐Simulated Reservoir Storage

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Accurate simulation of reservoir outflow is essential for integrated water resource management. However, the limited availability of operational data for reservoirs often hinder the accuracy of outflow simulations. Satellite remote sensing, combined with water balance approaches, provides an effective solution for calculating outflows. However,

Seesaw Shift in Sea Surface Height Drives Spring Decline of the Antarctic Slope Current in the Cosmonaut Sea, East Antarctica

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The Antarctic Slope Current (ASC) plays a crucial role in modulating the transport of warm Circumpolar Deep Water onto the continental shelves, influencing ice shelf melting and Antarctic ice sheet mass balance. However, our understandings of the ASC variability and its driving mechanisms remain limited due to observational constraints in the ...
