Current, temperature and salinity data obtained on the western slope of the Stolpe Sill in October 1998 were analysed to identify the processes responsible for the transport of dense, near-bottom water from the Bornholm Deep into the Stolpe Channel. Westward transport in the deep layer was opposed to the wind direction. The longitudinal current component was considerably smaller than the latitudinal one. Long waves (with periods T > 10 h) and short-period oscillations (T < 2 h) were recorded in the form of wave trains. The rotary-component spectral method revealed a dominant internal wave with a period close to the local inertial period (T = 14.6 h). High-frequency current fluctuations (time scales 2-30 min) were regarded as a quasi-horizontal turbulence caused by interaction between the long waves and the complicated bottom topography.
