!   This is a setup for generating an ocean mixed layer including the effects
!   of Stokes drift (Langmuir circulation) and wave breaking, based on the
!   case described in Noh, Y., H.S. Min and S. Raasch (2004): Large-eddy
!   simulation of the ocean mixed layer: The effects of wave breaking and
!   Langmuir circulation. J. Phys. Oceanogr., 34, 720-735.
