| The hypothesis of isopycnal mixing was used in order to calculate the percentages of South Atlantic Central Water (SACW) in proportion to North Atlantic Central Water (NACW) in the intermediate layer between the density surfaces of sigma sub(t) = 26.5 and sigma sub(t) = 27.2 along a zonal section at 20 degree 10'N. In this profile the SACW distribution was "conserved" within an offshore distance of about 370 km from the African coast during two observation periods with a time lag of ten months. The SACW distribution along the section follows from the zonal energy structure of the geostrophic meridional flow within this layer. It is concluded that the intermediate geostrophic meridional motions are adjusted to the local profile of the continental slope H(x). |

| A meso-scale CTD survey was conducted off Cape Ghir (31 degrees N) from 29 September to 3 October 1992, with the inspection of mass-field structures in the 300 dbar layer as its main objective, and relatively large tongue of cold surface water as the subject of investigation. This filament of upwelled water extends about 200 km seaward from the coastal zone of Morocco. Our CTD survey included two zonal transects 213 km in length, sampled synchronously by R/Vs Hudson along 31 degrees 30' N and A. v.Humboldt along 30 degrees 30' N. A meridional section followed the shelf edge at 10 degrees 10' W, and five zigzag sections were carried out above the Cape Ghir Plateau (CGP). Data resulting from an extended transect, sampled ten days earlier between 9 degrees... |
