| A quasi-meridional hydrographic section carried out between 60-degrees and 20-degrees-N offshore from the European and African continental slopes is analyzed in terms of water masses and zonal transports in and out of the eastern boundary. Outstanding features of the meridional distribution of water masses are focused on, such as the transition between North Atlantic and South Atlantic Central Waters at 20-degrees-25-degrees-N, the properties and anticyclonic circulation of the Rockall Channel mode water, and the northern boundary of the large-scale Mediterranean Water plume at about 50-degrees-N. An eastward transport of about 11 X 10(6) m3 s-1 is found to enter the eastern boundary layer at densities lower than 27.25 and feed southward alongshore... |

| The physical and biogeochemical components of nutrients and inorganic carbon distributions along WOCE line A14 are objectively separated by means of a constrained least-squares regression analysis of the mixing of eastern South Atlantic water masses. Contrary to previous approaches, essentially devoted to the intricate South Atlantic circulation, this work is focused on the effects of circulation on nutrients and carbon biogeochemistry, with special emphasis on the stoichiometry and the rate of mineralization processes. Combination of nutrient and apparent CFC-age anomalies, derived from the mixing analysis, indicate faster mineralization rates in the equatorial (12 x 10(-2) mumol P kg(-1) yr(-1)) and subequatorial (5.3 x 10(-2) mumol P kg(-1) yr(-1)) than... |
