Short summary

We studied a rotating body of water south of the Canary Islands, known as an intrathermocline eddy. With an isolated core below the surface, it showed distinct energy patterns and structure. Satellite images and field data suggest it interacted with productive coastal waters, while its year-long life cycle unfolded surrounded by other vortices. These features point to a role in offshore transport and regional circulation, emphasizing the need for sustained, integrated ocean monitoring.
