Mesoscale dynamics of an intrathermocline eddy in the Canary Eddy Corridor

Ocean Science
Abstract. High-resolution observations of an intrathermocline eddy were conducted in November 2022 within the Canary Eddy Corridor. Formed in early summer 2022, this mature mesoscale eddy exhibited a vertical extent of 550 m, with its core centered at 110 m depth, and a segmented horizontal structure comprising a 23 km radius solid-body core surrounded

Multicore structures of oceanic mesoscale eddies

Environmental Research Letters
Abstract Mesoscale eddies observed in coarse-resolution data typically appear with a single center. However, recent altimetry observations of Surface Water and Ocean Topography (SWOT) reveal many eddies own multicore structures. This study investigates the differences between these multicore eddies and single-core eddies and how the ...
