| Zusammenfassung |
| During the 1992-1993 oceanographic cruise of
the Spanish R/V Hespérides, recording equipment was deployed in the Bransfield
Strait. Six Aanderaa RCM7 current meters and three Aanderaa WLR7 tide gauges
were successfully recovered after an operation period of 2.5 months. Relevant
features of the time series obtained are presented and discussed in this paper.
The emphasis is placed on the tidal character of the currents and the relative
importance of tidal flow in the general hydrodynamics of the strait. For these
purposes a dense grid of hydrographic stations, completed during the BIOANTAR 93
cruise, is used. Preliminary geostrophic calculations relative to a 400 m depth,
yield current velocities of around 0.20 m s-1 in the study area,
whereas the magnitude of tidal currents is seen to be 0.30-0.40 m s-1. |
