| Zusammenfassung |
| The greater Agulhas Current has been shown to be a key link in the global
thermohaline circulation and an increased understanding of this current
system is therefore of more than just local interest. Knowledge on the
Agulhas Current system has in fact increased enormously over the past 30
years. This review covers some aspects of what has been learnt on the
northern and the southern parts of the Agulhas Current proper and their
influence on the waters and circulation of the adjoining continental shelf.
It also discusses the Natal Pulse and new information that has been gained
on how it is triggered and what influence it has. It deals with the Agulhas
retroflection, the shedding of Agulhas rings and the movement and
characteristics of these rings that contributes to the meridional
overturning circulation of the global ocean. The Agulhas Return Current
forms part of the final outflow of the system and current knowledge on that
current is appraised. The sources of the Agulhas Current have been a
controversial subject for many years and this dispute continues. This is
described and discussed, based on what information has been gained from
research over the past three decades. Building on what is currently known,
some suggestions are given on the most important remaining knowledge gaps
and how these could most efficaciously be filled. |
