Automated Eddy Identification and Tracking in the Northwest Pacific Based on Conventional Altimeter and SWOT Data

Remote Sensing
Eddy identification and tracking are essential for understanding ocean dynamics. This study employed the elliptical Gaussian function (EGF) simulations and the py-eddy-tracker (PET) algorithm, validated by Surface Velocity Program (SVP) drifter data, to ...

Analysis of a Permanent Downwelling Zone in the East China Sea Using the Hybrid Coordinate Ocean Model (HYCOM)

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Vertical motion in the East China Sea is examined using a 1/12.5° regional HYbrid Coordinate Ocean Model simulation from 2018 to 2022. Here we present an area of persistent downwelling ∼200 km East‐Northeast of Taiwan where the Kuroshio flows along the continental slope.

Contrasting Near‐Inertial Internal Wave Responses to Single Versus Consecutive Typhoons Forcing in the Xisha Islands Waters, South China Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Mooring observations capture the responses of near‐inertial internal waves (NIWs) to three sequential typhoons (Trami, Yinxing, and Man‐yi) over the Xisha Islands from October to November 2024, using high‐resolution ADCP measurements. Typhoon forcing excites near‐inertial kinetic energy (NIKE) mainly in the 0–100 m layer. Although >90% of NIKE

Submesoscale Eddies in the Taiwan Strait Observed by High-Frequency Radars: Detection Algorithms and Eddy Properties

, 2017
This study compared the efficiencies of two widely used automatic eddy detection algorithms—that is, the winding-angle (WA) method and the vector geometry (VG) method—and investigated the submesoscale eddy properties using surface current observations ...

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.

Submesoscale Frontogenesis Drives Strong Finescale Tracer Subduction

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Vertical exchange between the surface mixed layer (ML) and the interior is important for biogeochemistry and air–sea interaction. Focused observations have consistently shown that submesoscale processes (horizontal scales of 0.1–10 km) generate substantial exchange of heat, freshwater, and biogeochemical tracers across the ML base ...

Submesoscale Variability and Basal Melting in Ice Shelf Cavities of the Amundsen Sea

Geophysical Research Letters
Melting of ice shelves can energize a wide range of ocean currents, from three‐dimensional turbulence to relatively large‐scale boundary currents. Here, we conduct high‐resolution simulations of the western Amundsen Sea to show that submesoscale eddies ...

Gulf of Maine Marine Heatwaves in Eddy‐Resolving and Non‐Eddy Resolving Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Marine heatwaves (MHWs), prolonged periods of anomalously high ocean temperatures, have major ecological and socioeconomic consequences. Predicting these events requires knowing which atmospheric and ocean processes control their onset, persistence, and intensification.

Mesoscale eddies and submesoscale structures of Persian Gulf Water off the Omani coast in spring 2011 [PDF]

, 2016
The Persian Gulf produces high-salinity water (Persian Gulf Water, PGW hereafter), which flows into the Sea of Oman via the Strait of Hormuz. Beyond the Strait of Hormuz, the PGW cascades down the continental slope and spreads in the Sea of Oman under ...

Infrared‐Guided Super‐Resolution of Remotely Sensed Passive Microwave Sea Surface Temperature

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract High‐resolution sea surface temperature (SST) is essential for weather forecasting and climate applications. Passive microwave (MW) SST offers largely cloud‐penetrating coverage but is coarse and spatially smoothed, whereas infrared (IR) SST resolves fine‐scale structures but is frequently cloud‐obscured.
