International audience  Nonlinear interaction in upper ocean transfers kinetic energy both up-and down-scales  Upper ocean balance and unbalanced motions contribute oppositely to energy cascade  Bi-directional energy cascade depends on relative importance of balanced vs. unbalanced motions and characteristics of the unbalanced motions
