Three-Dimensional Parameterization of Submesoscale Eddy From HiSea-II Imagery
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe detection of submesoscale eddies is limited by altimeter resolution and the complex dynamics of eddy formation and dissipation, resulting in an incomplete understanding of their structure.

Topological Feature Tracking for Submesoscale Eddies
Geophysical Research Letters, 2022 Current state-of-the art procedures for studying modeled submesoscale oceanographic features have made a strong assumption of independence between features identified at different times. Therefore, all submesoscale eddies identified in a time series were studied in aggregate.

Evidence of submesoscale coastal eddies inside Todos Santos Bay, Baja California, México
Ocean and Coastal Research, 2022 Submesoscale eddies (1-10 km diameter) were identified using surface velocity observations obtained from a high-frequency radar system (HFR) operated in Todos Santos Bay (TSB), Baja California, Mexico.

Frontiers in Marine Science, 2023 Submesoscale oceanic structures (<10-20 km) such as eddies and fronts are often difficult to describe given the influence of the mesoscale. In order to characterize the surface signatures of submesoscale structures, we utilize a custom spatial ...

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.

Turbulent mixing, restratification, and phytoplankton growth at a submesoscale eddy [PDF]
Geophysical Research Letters, 2016 AbstractHigh‐resolution large‐eddy simulations are used to study the influence of submesoscale mixed layer instability and small‐scale turbulence on phytoplankton growth in light‐limited conditions. Four simulations are considered with small‐scale turbulence driven by varying levels of surface cooling.
