Abstract
Processes in the oceanic bottom boundary layer (BBL) have received much less attention in ocean modeling than surface mixed layer processes. Since the ocean is mainly driven from the surface, high vertical resolution is traditionally placed in the upper ocean. Consequently, the only effect of the lower boundary was considered to be its effect as a sink for momentum and energy. But BBLs are also the place for enhanced diapycnal mixing (especially over steep and rough topography), wind-driven cross-slope transports of tracers and particles (including sediment), and last but not least, gravity-driven dense water spreading. Thus, they play an important role for both local and large-scale ocean dynamics.
