DETERMINATION OF THE ICE SHEET SURFACE ELEVATION PROFILES ALONG THE INLAND TRACKS IN ANTARCTICA BY KINEMATIC GPS-OBSERVATIONS

Лëд и снег, 2015
Surface height profiles of the Antarctic ice sheet were derived from kinematic GPS observations on continental traverses with an accuracy of20 cm. The spectral analysis of the height profile allowed distinguishing different zones of distinct relief ...

SWOT Sheds Light on Seiche Oscillations Within Atoll Islands

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract This study investigates the occurrence of surface elevation oscillations, known as seiches, at the atoll scale. We show that the innovative Ka‐band Radar Interferometer (KaRIn) onboard the Surface Water Ocean Topography (SWOT) satellite makes it possible to visualize seiche‐like structures within lagoons of French Polynesia.

Efficiency of Optimized Approaches for Gravity Operator Modeling

Remote Sensing
Numerical tesseroid and radial-type approaches are presented and compared in terms of their efficiency for deriving the regional geoid height, vertical gravity, and gradiometric anomalies from sea floor topography grids. The vertical gradient function is

Characteristics of ocean-reflected short radar pulses with application to altimetry and surface roughness determination [PDF]

, 1972
Current work related to geodetic altimetry is summarized. Special emphasis is placed on the effects of pulse length on both altimetry and sea-state estimation.

Spatial Altimetry and Continental Waters

, 2016
The transfer of energy and water, as well as gaseous components, in the soil–plant–atmosphere system plays a crucial role in many processes involved in climate change. The surface energy balance drives both evapotranspiration (closely linked to the CO2 flux) and sensible heat flux.

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

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.

Quantifying Eulerian Eddy Leakiness in an Idealized Model [PDF]

, 2019
An idealized eddy‐resolving ocean basin, closely resembling the North Pacific Ocean, is simulated using MITgcm. We identify rotationally coherent Lagrangian vortices (RCLVs) and sea surface height (SSH) eddies based on the Lagrangian and Eulerian ...
