Mean current and temperature data from the Gulf of Cádiz

During "Meteor" cruise 23 in spring 1971 intensive investigations of the Mediterranean outflow in the Gulf of Cidiz were carried out. In order to give a budget of the inflow and outflow numerous CTD-stations were taken. The observations also included six moored current meter arrays deployed in the known outflow channels. The considerations given here are based mainly on three hydrographic sections, current meter records averaged over one month, and geological observations from the bed forms beneath the Mediterranean undercurrent. The results show that the outflow essentially is determined by the bathymetry of the area. At least four separate outflow channels could be confirmed. The volumentric transport rates of three of them were calculated. These channels are the northerly near shelf branch (0.40 * 10**6 m**3 * sec**-1), the main branch (1.39 * 10**6 m**3 * sec**-1) in southwesterly direction, and an intermediate branch (0.24 * 10**6 m**3 * sec**-1) found between both. In a static box model the progressive mixing of 0.95 * 10**6 m**3 * sec**-1 pure Mediterranean Water with 1.97 * 10**6 m**3 * sec**-1 North Atlantic Central Water is demonstrated.
