    Notes: Analysis of manganese and zinc concentrations in the scales of salmon and trout from a number of sites showed significant dependence of the levels of these metals in the scales on the levels in the environment. There is some evidence to suggest that in trout scales there is a minimum concentration of zinc above which there is a direct proportion between environmental and scale concentration. It is also possible that the response of trout to environmental zinc differs from that of salmon.

    Description / Table of Contents: Zusammenfassung Das Ausströmen des Mittelmeerwassers geschieht in zwei getrennten (oberen und unteren) Kernmassen, die sich entlang einer deutlich abgegrenzten Route zwischen Gibraltar und Cabo São Vicente ausbreiten. Ihre physikalischen und chemischen Eigenschaften werden ausführlich beschrieben und als Beweis dafür benutzt, daß man den oberen Kern als getrennte Wassermasse behandeln kann. Es wird auch gezeigt, daß dieser Kern beim Durchzug durch den Golf von Cadiz in seiner Konzentration um 20% abgeschwächt wird, wohingegen die untere Kernkonzentration fast konstant bleibt. Außerdem gibt es Anzeichen für ein Abkühlen und Absinken des Schelfwassers im Winter, welches durch das Vorhandensein von Cañons in diesem Gebeit verstärkt zu werden scheint.
    Abstract: Résumé Le courant d'écoulement méditerranéen est considéré comme comportant deux couches distinctes (la supérieure et l'inférieure), qui suivent une route bien définie entre Gibraltar et le Cap Saint-Vincent. Leurs propriétés physiques et chimiques font l'objet d'une discussion détaillée et sont utilisées comme témoins permettant de traiter la couche supérieure comme une masse d'eau séparée. On montre également que cette couche subit une déperdition de concentration de 20% lors de la traversée du Golfe de Cadix, alors que celle de la couche inférieure reste presque constante. De plus, il a été constaté un certain refroidissement hivernal et un enfoncement de l'eau du plateau continental, qui semble renforcé par la présence des canyons les plus importants de la région.
    Notes: Summary The Mediterranean outflow is considered as two separate cores (upper and lower) which follow a well defined route between Gibraltar and Cabo São Vincente. Their physical and chemical properties are discussed in some detail and used as evidence for treating the upper core as a separate water mass. This core is also shown to suffer a 20% depletion in its concentration as it traverses the Gulf of Cadiz, whereas that of the lower core remains almost constant. In addition there was some indication of winter cooling and sinking of the shelf water which seems to be enhanced by the presence of the more prominent canyons in the area.
