Comparison between Eulerian diagnostics and finite-size Lyapunov exponents computed from altimetry in the Algerian basin [PDF]

open access: yes, 2008
Transport and mixing properties of surface currents can be detected from altimetric data by both Eulerian and Lagrangian diagnostics. In contrast with Eulerian diagnostics, Lagrangian tools like the local Lyapunov exponents have the advantage of ...

Inversion of Seafloor Topography in the Gulf of Mexico Based on Convolutional Neural Network Integrated With Multisource Gravity Data and Bathymetric Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Large-scale, high-precision seabed topography data serves as the foundation for scientific research on Earth’s shape and geological structure. Satellite altimetry data combined with classical gravity field inversion methods are important means for

Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

open access: yesGeophysical 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.

The application of Skylab altimetry to marine geoid determination [PDF]

open access: yes
The author had identified the following significant results. The major results can be divided broadly into two groups. One group is concerned with the effects of errors inherent in the various input data, such as the orbit emphemeris, a priori geoid etc.

Decadal Variability of Eddy Kinetic Energy Along the Eastern Boundary of the Subtropical South Indian Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Using more than three decades (1993–2024) of satellite altimetry and ocean reanalysis, we reassess the dominant timescales of low‐frequency mesoscale eddy variability along the eastern boundary of the subtropical South Indian Ocean. After removal of the seasonal cycle, eddy kinetic energy (EKE) is primarily modulated on decadal timescales (8 ...

Satellite altimetry [PDF]

open access: yes
Since altimetry data are not really old enough to use the term data archaeology, Mr. Cheney referred to the stewardship of these data. He noted that it is very important to document the basis for an altimetry data set as the algorithms and corrections ...

Monitoring Continental Surface Waters by Satellite Altimetry

open access: yesSurveys in Geophysics, 2008
The monitoring of continental water stages is a requirement for meeting human needs and assessing ongoing climatic changes. However, regular gauging networks fail to provide the information needed for spatial coverage and timely delivery. Although the space missions discussed here were not primarily dedicated to hydrology, 18 years of satellite ...

SWOT Satellite Observations of the Kakhovka Dam Break Flood Highlight Limitations of Outburst Flood Models

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 6 June 2023 failure of the Kakhovka Dam generated a catastrophic outburst flood, leading to loss of life and infrastructure damage. During the flood, daily measurements of water surface elevation were collected by the SWOT satellite, providing the first direct, high‐resolution 2D measurements of a large outburst flood.

Comparison of Ocean Dynamics with a Regional Circulation Model and Improved Altimetry in the North-Western Mediterranean

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2008
The spatial and temporal resolution of satellite altimetry is usually sufficient for monitoring the changes of sea surface topography in the open ocean.
