Recent Advances on Oceanic Mesoscale Eddies II

Dear Colleagues,

Mesoscale eddies are energetic coherent structures that play a crucial role in the ocean. They have typical horizontal scales ranging from 10–100 km and lifetimes from months to sometimes years. They can connect the coastal and the open ocean, generate a downscale energy cascade, and trap and transport heat, salt, pollutants and biogeochemical tracers at long distances. They can also modulate the mixed layer depth, regulate air–sea heat and gas fluxes and influence local winds, clouds and rainfall. As a result, they have a profound impact on the ocean–atmosphere–biosphere system. However, the myriad mechanisms that control or impact all the above-mentioned components of the ocean are not yet fully explored.

Major breakthroughs in remote sensing have paved the way for a global understanding of the oceanic circulation. Automatic eddy detection and tracking algorithms, applied to low-resolution altimetric data, are efficient tools to study the dynamics of mesoscale eddies. To complete these standard techniques, new methods such as deep learning have been developed to analyse visible images (SST, Ocean Colour) that contain higher spatial resolution eddy signatures but can be corrupted by cloud coverage. These recent advances, combined with in situ data (Argo floats, gliders, surface drifter, oceanographic cruises, etc.) and eddy resolving models, provide invaluable information on surface dynamics and the three-dimensional nature of eddies.

The aim of this Special Issue is to advance our understanding of complex mesoscale eddy activity. Therefore, this SI welcomes manuscripts dealing with eddy dynamics, eddy properties variability, transport, or impact on ocean circulations and on marine ecosystems We accept contributions based on standard and new methods that can permit the improvement of mesoscale eddy identification and knowledge. We also strongly encourage works that combine these remote sensing techniques with theory, in situ observations data, and/or modelling output to explore complex physical–biological interactions driven by mesoscale eddies or to unveil the vertical structure of surface imprints of eddies detected by satellites.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.
