Current meter records from a mooring atop a large seamount in the eastern North Pacific (Fieberling Guyot) are dominated by diurnal fluctuations at depths close to the seamount summit depth. These oscillations are driven by diurnal tides to have amplitudes of 0.2--0.4 m/s or more and exhibit characteristics of seamount trapped waves (i.e., coastal trapped waves for a submerged periodic coast). These waves rectify to produce anticyclonically directed low-frequency currents in the vicinity of the seamount summit of magnitude comparable to the rms wave amplitude. Mean currents over several months are directed across isobaths at depths more than 200 m shallower than the seamount summit. Currents closer to the bottom have a component directed toward deeper water and are ageostrophic as a result of wave rectification. Internal wave band currents are more energetic with increasing proximity to the local bottom, presumably as a result of wave reflection and focussing. ¿American Geophysical Union 1991
