Abstract
Profiles of salinity and potential temperature in the deep ocean are presented which suggest the
characteristic signature of two complementary mixing processes: vertical mixing within ~50-m-thick
layers at boundaries and topographic features and lateral advection and eventual smearing of these mixed
layers along iopycnal surfaces. The combined effect of these two processes is often parametrically
disguised as a vertical eddy diffusivity in one-dimensional models. An estimate shows that the two
processes can account for all the vertical mixing in the deep ocean without any vertical diffusion in the
interior.
