Abyssal plain hills and internal wave turbulence

Hans van Haren

Data sets

CTD and current meter data from SONNE cruises SO239 and SO240 Hans van Haren

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.
