Detection and Identification of Mesoscale Eddies in the South China Sea Based on an Artificial Neural Network Model—YOLOF and Remotely Sensed Data

open access: yesRemote Sensing, 2022
Mesoscale eddies are typical mesoscale ocean phenomena that exist widely in all oceans and marginal seas around the world, playing important roles in ocean circulation and material transport.

Global contributions of mesoscale dynamics to meridional heat transport [PDF]

open access: yesOcean Science, 2021
Mesoscale ocean processes are prevalent in many parts of the global oceans and may contribute substantially to the meridional movement of heat. Yet earlier global surveys of meridional temperature fluxes and heat transport (HT) have not formally ...

Studying the influence of cold-core mesoscale ocean eddies on sound propagation based on the parabolic equation method

open access: yesAIP Advances, 2023
Mesoscale vorticity is an important factor that affects the non-uniform horizontal and vertical distribution of hydrologic elements in the ocean. In this paper, temperature and salinity data from measured mesoscale cold-core eddies during a voyage within

Taking into Account the Eddy Density on Analysis of Underwater Glider Motion

open access: yesJournal of Marine Science and Engineering, 2022
Mesoscale eddies play an important role in regulating the global ocean ecosystem and climate variability. However, few studies have been found to focus on the survey of the underwater gliders (UGs) motion performance inside mesoscale eddies.

Spatiotemporal Variability of Mesoscale Eddies in the Indonesian Seas [PDF]

open access: yesRemote Sensing, 2021
Mesoscale eddies are ubiquitous in the world ocean and well researched both globally and regionally, while their properties and distributions across the whole Indonesian Seas are not yet fully understood. This study investigates for the first time the spatiotemporal variations and generation mechanisms of mesoscale eddies across the whole Indonesian ...

Impact of Mesoscale Eddies on Deep Chlorophyll Maxima [PDF]

open access: yesGeophysical Research Letters, 2021
AbstractDeep Chlorophyll Maxima (DCM) are ubiquitous features in stratified oceanic systems. Their establishment and maintenance result from hydrographical stability favoring specific environmental conditions with respect to light and nutrient availability required for phytoplankton growth.
