L'auteur considère le système 3D d'équations décrivant la dynamique de l'océan à grande échelle en coordonnées cartésiennes. Il démontre, pour tout coefficient de viscosité et toute donnée initiale, l'existence et l'unicité d'une solution sur un intervalle de temps [0,T] arbitrairement, ainsi que la continuité en temps sur l'intervalle [0,T] de la norme ‖uˆx‖.

For the 3D system of equations describing large-scale ocean dynamics in the Cartesian coordinate system existence and uniqueness of a solution on an arbitrary time interval [0,T] is proved and the norm ‖uˆx‖ is shown to be continuous in time on [0,T].
