Zusammenfassung |
The structures of the hydrographic fronts separating the Atlantic-origin
waters from ambient waters in the northern Nordic Seas are discussed. Flows
of the western and eastern branches of the West Spitsbergen Current create
the Atlantic domain borders and maintain these fronts. This work is based on
previous research and on investigations carried out in the project DAMOCLES (Developing
Arctic Modelling and Observational Capabilities for Long-term Environmental
Studies). Most of the observational data were collected during the R/V
Oceania cruises. The main focus of the paper is the western border
of the Atlantic domain – the Arctic Front, alongfrontal and transfrontal
transports, and the front instability and variability. The alongfrontal
baroclinic jet streams were described as a significant source of the
Atlantic Water and heat in the Nordic Seas. The baroclinic instability and
advection of baroclinic eddies which occurs due to this instability were
found to be the main transfrontal transport processes. Most of the Atlantic
Water transported by the western branch recirculates west and southward. The
eastern branch of the West Spitsbergen Current provides most of the Atlantic
Water entering the Arctic Ocean. Both processes are very important for the
Arctic and global thermohaline circulation. |
