Multidecadal Oscillation Masks Ocean Wave Climate Trends in 75‐Year Global Wave Hindcast

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The observed increases in temperature and sea level are clearly driven by climate change, and these trends are projected to accelerate in the future. The ocean surface wave characteristics are projected to change depending on the climatic elements.

Neural Network‐Based Methods for Ocean Surface Wave Measurement Using Submarine Distributed Acoustic Sensing (DAS)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Two new data‐driven models for estimating ocean surface waves from distributed acoustic sensing (DAS) submarine cable strain rate are developed using supervised machine learning on a 10‐day data set collected offshore of Oliktok Point, Alaska.

Validation of Multisource Altimeter SWH Measurements for Climate Data Analysis in China’s Offshore Waters

Remote Sensing
Climate data derived from long-term, multisource altimeter significant wave height (SWH) measurements are more valuable than those obtained from a single altimeter source.

Overview of SWALIS, KaRADOC and HOMARDS: A Suite of Airborne Radars to Support Satellite Earth Observation Missions. SWOT Calibration/Validation Campaign in South Rhine

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
The figure provides an overview of the uncalibrated NRCS measurements taken above the La Chèze water storage. The path is visible on an satellite map as traces showing higher reflected power (brighter areas) compared to the surrounding ground. ABSTRACT This paper presents the different airborne radar systems which are developed at IETR (Institut d ...

Detailed Monitoring of the Antarctic Marginal Ice Zone by Satellite Radar Altimeter Synergy—A Study of the Weddell Sea/Indian Ocean Sector in July 2017

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The wave‐affected Marginal Ice Zones (MIZ) is a key region of air‐ice‐ocean interactions in the Southern Ocean (SO). However, challenges still remain for the large‐scale observation of the MIZ. In this study, we use four concurrent radar altimeters to retrieve the wave‐affected MIZ in the eastern Weddell Sea‐Indian Ocean sector, which was ...

Observing Interactions Between Waves, Winds, and Currents From SWOT

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission enables, for the first time, two‐dimensional (2D) mapping of significant wave height Hs $\left({H}_{s}\right)$ at kilometer‐scale resolution. Using data from SWOT's Ka‐band Radar Interferometer (KaRIn), this study investigates interactions between surface waves, winds, and ...
