| Zusammenfassung |
| Measurements of the slope current at two
locations north-west of Ireland have been made between April and December 1994,
40 m above the seabed in a water depth of 660 m. A persistent poleward
along-slope current was observed at both locations, with measured means of 10
and 21cms–1 respectively. A CTD transect across the slope near one
mooring indicated the presence of a light, warm, saline core of water at the
shelf edge. Peak currents were O(50)cms–1, with strongest mean
flow at the location with steeper slope. Variability at sub-tidal periods,
principally 2–5 and 11–12 days, was apparent. The shorter-period variability was
well correlated with coastal sea-level variations measured at a land point near
to one of the moorings. The variability in the slope current at this period
appeared to be a result of the warm current core movement up/down slope,
probably as a result of interaction with higher-mode shelf waves. Some
suggestion of a bottom-trapped diurnal wave was also found at one location. |
