    Notes: Heat and freshwater transports through Fram Strait are understood to have a significant influence on the hydrographic conditions in the Arctic Ocean and on water mass modifications in the Nordic seas. To determine these transports and their variability reliable estimates of the volume transport through the strait are required. Current meter moorings were deployed in Fram Strait from September 1997 to September 1999 in the framework of the EU MAST III Variability of Exchanges in the Northern Seas programme. The monthly mean velocity fields reveal marked velocity variations over seasonal and annual time scales, and the spatial structure of the northward flowing West Spitsbergen Current and the southward East Greenland Current with a maximum in spring and a minimum in summer. The volume transport obtained by averaging the monthly means over two years amounts to 9.5 ± 1.4 Sv to the north and 11.1 ± 1.7 Sv to the south (1 Sv = 106 m3s−1). The West Spitsbergen Current has a strong barotropic and a weaker baroclinic component; in the East Greenland Current barotropic and baroclinic components are of similar magnitude. The net transport through the strait is 4.2 ± 2.3 Sv to the south. The obtained northward and southward transports are significantly larger than earlier estimates in the literature; however, within its range of uncertainty the balance obtained from a two year average is consistent with earlier estimates.

    Notes: [Auszug] The overflow and descent of cold, dense water from the sills of the Denmark Strait and the Faroe–Shetland channel into the North Atlantic Ocean is the principal means of ventilating the deep oceans, and is therefore a key element of the global thermohaline circulation. Most computer ...

    Description / Table of Contents: Zusammenfassung Die beobachtete Verteilung und Ausbreitung von salzarmen Wasser arktischen und subarktischen Ursprungs wird für das Gebiet des zentralen Island-Färöer-Rückens und der Färöer beschrieben. Nach Absinken entlang der Polarfront nordwestlich der Färöer breitet sich das salzarme Wasser als Zwischenwasser entlang dem Abfall des nördlichen Färöer-Sockels nach Südosten aus und füllt die mittleren Tiefen des Färöer-Shetland-Kanals. Da nur ein Bruchteil dieses Wassers aus dem Färöer-Bank-Kanal in den Nordostatlantik gelangt, stützen die Daten die Annahme einer Rezirkulation im Färöer-Shetland-Kanal. Die Verteilung des salzarmen Zwischenwassers zeigt weiterhin, daß der zentrale Island-Färöer-Rücken nicht direkt überströmt wird, sondern daß Mischungsprozesse in der Kammregion und Advektion des Wassers aus dem Färöer-Bank-Kanal die hydrographische Struktur der südwestlichen Flanke bestimmen.
    Abstract: Résumé La distribution et la propagation de l'eau peu salée d'origine arctique et subarctique est décrite au moyen des données provenantes de la région centrale du seuil de Islande-Féroé et des îles Féroé. Après de plonger le long du front polaire au nordouest de Féroé, l'eau peu salée se propage comme l'eau intermédiaire vers le sud-est au délà de la pente nord du socle de Féroé et remplit les profondeurs moyens du canal de Féroé-Shetland. Comme seulement une partie de ces eaux du canal du Banc de Féroé arrive à l'Atlantique, les données appuient l'hypothèse d'une recirculation dans le canal de Féroé-Shetland. Les données montrent en plus, que le seuil de Islande-Féroé n'est pas traversé directement. La structure hydrographique du flanc sud-ouest du seuil de Islande-Féroé est déterminée par des processus de mélange dans la région de la crête et par la convection horizontale de l'eau du canal de Banc de Féroé.
    Notes: Summary The observed distribution and the spreading of low salinity waters of arctic and subarctic origin is discussed for the central Iceland-Faroe ridge and for the area around the Faroe Islands. After sinking along the polar front northwest of the Faroes the low salinity water spreads over the northern Faroe slope and into the Faroe-Shetland channel at intermediate levels. The amount of intermediate water leaving the Faroe-Bank channel into the northeastern Atlantic is small compared to its availability in the Faroe-Shetland channel, hence supporting the hypothesis of a re-circulation for the area east of the Faroes. The observations of intermediate water furthermore show no direct flow across the central Iceland-Faroe ridge but they reveal that mixing processes over the sill and advection of waters from the Faroe-Bank channel outflow determine the hydrographic structure of the southwestern flank of the Iceland-Faroe ridge.
