Short summary

This paper presents high-resolution temperature observations and turbulence estimates from a hilly abyssal "plain" in Pacific nodule areas. Although turbulence levels are considerably lower than over steep topography, a bottom boundary layer, if existent, varies in height over scales far exceeding that of an Ekman layer. This variation is associated with internal wave motions affecting the near-bottom turbulence and thus probably the associated sediment reworking.
