Detecting surface geostrophic currents using wavelet filter from satellite geodesy

Science in China Series D: Earth Sciences, 2007
According to the features of spatial spectrum of the dynamic ocean topography (DOT), wavelet filter is proposed to reduce short-wavelength and noise signals in DOT. The surface geostrophic currents calculated from the DOT models filtered by wavelet filter in global and Kuroshio regions show more detailed information than those from the DOT models ...

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.

Response of the thermohaline front and associated submesoscale features in the Korea Strait to wind variation during autumn

Frontiers in Marine Science
In the present study, a three-dimensional numerical simulation with a 1 km grid spacing is conducted to investigate the response of the thermohaline front in the northern Korea Strait (KS) and its associated submesoscale features to wind variation.

Use of recent geoid models to estimate mean dynamic topography and geostrophic currents in South Atlantic and Brazil Malvinas confluence

Brazilian Journal of Oceanography, 2012
The use of geoid models to estimate the Mean Dynamic Topography was stimulated with the launching of the GRACE satellite system, since its models present unprecedented precision and space-time resolution. In the present study, besides the DNSC08 mean sea

The applicability of the T/S method to geopotential anomaly computations in the Northeast Atlantic [PDF]

, 1983
Methods are tested for computing geopotential anomalies from temperature data in the subtropical Northeast Atlantic. Mean temperature-salinity, salinity-depth and density-depth relationships are determined for 3 x 3° squares, using hydrographie data ...

Strong enhancement of chlorophyll a concentration by a weak typhoon

, 2010
Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concentrations in the middle of the South China Sea (SCS) from 1997-2007.

Response of Ocean Mesoscale Coherent Eddies to Global Warming

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale vertically coherent ocean eddies—defined here as eddies maintaining rotational coherence across depth—play a fundamental role in Earth's climate system by redistributing heat, salt, and other tracers. Yet it remains unclear how these eddies will respond to global warming.

High‐Resolution Observations Unveil (Sub)Mesoscale Heat Fluxes Shaping Upper‐Ocean Heat Content

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Upper‐ocean heat content (UOHC) modulates air–sea exchange in tropical regions; however, its variability at (sub)mesoscale remains insufficiently resolved. Here we combine Surface Water and Ocean Topography (SWOT) observations with high‐resolution glider sections in the northeastern tropical Pacific, where mesoscale eddies and sharp frontal ...

The Equations of Magnetoquasigeostrophy [PDF]

, 2013
The dynamics contained in magnetized layers of exoplanet atmospheres are important to understand in order to characterize what observational signatures they may provide for future observations. It is important to develop a framework to begin studying and

A Complete Formula of Ocean Surface Absolute Geostrophic Current.

Scientific reports, 2020
Absolute geostrophic current at the ocean surface (S) contains three components: (1) absolute geostrophic current at the geoid undulation (N), (2) geostrophic shear (between S and N) due to horizontal gradient of dynamic ocean topography, and (3) geostrophic shear (between S and N) due to horizontal gradient of density.
