Parameterization of Submesoscale Eddy-Rich Flows Using a Stochastic Velocity Model

Journal of Atmospheric and Oceanic Technology, 2006
Abstract In light of the recent high-resolution radar data of surface velocity, which have revealed submesoscale eddies between the Florida Current and the coast, an objective method of detecting eddies and estimating their parameters such as center coordinates, size, and intensity is suggested.

Submesoscale eddies near the Kuril Straits: Asymmetric generation of clockwise and counterclockwise eddies by barotropic tidal flow [PDF]

, 2012
High spatial resolution thermal infrared (TIR) images derived by the LANDSAT Thematic Mapper (TM) sensors show the presence of numerous small-scale eddies near the Kuril Islands.

Automatic Identification of Ocean Eddies in SAR Using U-Net Convolutional Neural Network

Russian Journal of Earth Sciences
The effect of mesoscale and submesoscale eddies on regional heat and freshwater transport, sea-ice dynamics, and bioproductivity in polar and subpolar regions is largely unknown.

The Influence of Submesoscale Motions on Upper-Ocean Chlorophyll: Case of Benguela Current Large Marine Ecosystem (BCLME)

Journal of Marine Science and Engineering
Submesoscale dynamics are critical modulators of upper-ocean biogeochemistry, yet their net influence on chlorophyll concentrations across seasonal to interannual timescales, particularly within productive regions like the Benguela Current Large Marine ...

The decay of cyclonic eddies by Rossby wave radiation [PDF]

, 1998
It is argued that because shallow water cyclones on a β-plane drift westward at a speed equal to an available Rossby wave phase speed, they must radiate energy and cannot, therefore, be steady. The form of the Rossby wave wake accompanying a quasi-steady

A visible record of eddies in the southern Mozambique Channel [PDF]

, 2003
The flows around Madagascar feed into the Agulhas Current, but there have been few hydrographic studies of the flow within the Mozambique Channel. Some cruise and altimetric data point to this being a region of high mesoscale activity, with eddies ...

A two-stage deep learning architecture for detection global coastal and offshore submesoscale ocean eddy using SDGSAT-1 multispectral imagery

Science of Remote Sensing
Submesoscale ocean eddies are essential oceanic phenomenon that control and influence the ocean energy cascade. Most existing eddy detection methods rely on low-resolution satellite altimeter data, which fail to capture submesoscale ocean features and ...

Submesoscale Eddy induced nitrate upwelling and effect on biological production in the upstream Kuroshio Current

Scientific Reports
While the Kuroshio, a western boundary current in the North Pacific, transports a large amount of nutrients in dark subsurface layers, it remains elusive whether and how these subsurface nutrients are supplied to continental shelves along southern coast ...

A Submesoscale Cascade‐Driven Mesoscale Seasonal Cycle in the Subtropics

Geophysical Research Letters
We show that the submesoscale inverse cascade almost entirely drives the mesoscale kinetic energy (KE) seasonal cycle in the interior subtropical gyre.
