| The subantarctic frontal zone surveyed during the April-May 1991 SUZIL cruise in the Crozet-Kerguelen Amsterdam area shows a strong horizontal (north to south) gradient of dissolved silicate, increasing with depth, from 5 to 10 mu molSi kg(-1) at 100 m, and 10 to 70 mu molSi kg(-1) at 600 m. The northern limit of this frontal zone, which is formed by the confluence of the Subtropical and Subantarctic Fronts, is delimited at the surface by the 2 mu molSi kg(-1) silicate isoline. Silicate-salinity diagrams also allow different water regimes to be positioned relative to the frontal zone. This sloping interface is between two water bodies, one to the north with more saline subtropical waters of less concentrated silicate than the southern one, corresponding to... |

| Plankton bioluminescence measurements were made in the Almeria-Oran frontal zone during December 1997 and January 1998. Vertical profiles of bioluminescence, chlorophyll fluorescence, temperature and salinity were obtained using a bathyphotometer associated with a CTD (conductivity-temperature-depth) probe on a rosette. The first leg of the cruise was a regular sampling along a cross section of the area. The second leg consisted of a repetitive sampling of twelve stations at each one of the eight sites located in different water masses. Hydrological data allowed a distinction from north to south of three different water masses: Mediterranean, frontal and Atlantic. The continuous sampling indicated an increased bioluminescence in the frontal zone, with high... |
