Cross-Domain Submesoscale Eddy Detection Neural Network for HF Radar [PDF]

Remote Sensing, 2021
With the rapid development of deep learning, the neural network becomes an efficient approach for eddy detection. However, previous work employs a traditional neural network with a focus on improving the detecting accuracy only using limited data under a single scenario.

Lagrangian and Eulerian characterization of two counter-rotating submesoscale eddies in a western boundary current [PDF]

, 2017
In recent decades, high-spatial resolution ocean radar and satellite imagery measurements have revealed a complex tangle of submesoscale filaments and eddies, in the surface velocity, temperature, and chlorophyll a fields.

On the Impact of Submesoscale Fronts on Mesoscale Eddies and Biological Productivity in the California Current System [PDF]

, 2021
Submesoscale motions are often not resolved in numerical models, although recent studies suggest that they interact with mesoscale processes. This might be particularly relevant for regions like the California Current System (CCS) where mesoscale ...

Weakened Submesoscale Eddies in the Equatorial Pacific Under Greenhouse Warming

Geophysical Research Letters, 2022
Submesoscale eddies in the equatorial Pacific induce a pronounced upward heat flux from the subsurface to the surface ocean. Yet their response to greenhouse warming and feedback on the mean‐state change remain unknown.

Multi-scale eddy identification and analysis based on deep learning method and ocean color data

International Journal of Digital Earth
Oceanic eddies are ubiquitous phenomena that facilitate the horizontal and vertical transportation of substances under the combination of ocean currents and the Coriolis force, thus they are crucial for the regulation of marine ecosystems.

Spatiotemporal Characteristics of the Near-Surface Turbulent Cascade at the Submesoscale in the Drake Passage. [PDF]

, 2023
Submesoscale currents and internal gravity waves achieve an intense turbulent cascade near the ocean surface [depth of 0–O(100) m], which is thought to give rise to significant energy sources and sinks for mesoscale eddies.

Heat transport by anticyclonic submesoscale eddies from the Beaufort Shelfbreak into the Canada Basin

Geoscience Letters
Eddies play an important role in the regulation of oceanic heat redistribution. This study investigates and analyzes submesoscale eddies in the upper ocean from the edge of the Beaufort Shelfbreak to the southern Canada Basin using data from the MITgcm ...

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...

Monitoring Mesoscale to Submesoscale Processes in Large Lakes with Sentinel-1 SAR Imagery: The Case of Lake Geneva

Remote Sensing, 2022
As in oceans, large-scale coherent circulations such as gyres and eddies are ubiquitous features in large lakes that are subject to the Coriolis force.
