The Canary Eddy Corridor: A major pathway for long-lived eddies in the subtropical North Atlantic
16 pages, 11 figures, 3 table We report, from remote sensing and in situ observations, a new type of permanent structure in the eastern subtropical Atlantic Ocean, that we call the ‘‘Canary Eddy Corridor’’. The phenomenon, is a zonal long-lived (43 months) mesoscale eddy corridor, whose source is th...

16 pages, 11 figures, 3 table We report, from remote sensing and in situ observations, a new type of permanent structure in the eastern subtropical Atlantic Ocean, that we call the ‘‘Canary Eddy Corridor’’.
