    Titles: Nonlinearly interacting entrainment due to shear and convection in the surface ocean

    Abstracts: This study reveals that sheared flow and convection nonlinearly interact in the ocean surface mixed layer, resulting in reduced entrainment of water from below the mixed layer. Overestimated mixed layer depths seen in many ocean general circulation model simulations may likely be ascribed to inappropriate representation of this nonlinear interaction by those models.
