c ISYNC		0 = concurrent coupling (SSTs passed to atmosphere are those
c                                        from the previous ocean timestep)
c               1 = sequential coupling (SSTs passed to atmosphere are
c                                        interpolated in time between ocean
c                                        timesteps)
c OVOLUME	Volume of ocean (m^3)
