| Zusammenfassung |
| Internal-tide energy fluxes are determined halfway over the southern
slope of Great Meteor Seamount (Canary Basin), using data from
combined CTD/LADCP yoyoing, covering the whole water column. The
strongest signal is semi-diurnal and is concentrated in the upper few
hundred meters of the water column. An indeterminacy in energy flux
profiles is discussed; it is argued that a commonly applied condition
used to determine these profiles is in fact invalid over sloping
bottoms. However, the vertically integrated flux can be established
unambiguously; the observed results are compared with the outcome of a
numerical internal-tide generation model. For the semi-diurnal
internal tide, the vertically integrated flux found in the model
corresponds well to the observed one. The observed diurnal signal
appears to be largely of non-tidal origin. |
