RT journal article T1 Seasonal variability of intermediate water masses in the Gulf of Cádiz: implications of the Antarctic and subarctic seesaw A1 Roque, David A1 Parras Berrocal, Iván Manuel A1 Bruno Mejías, Miguel A1 Sanchez Leal, Ricardo F. A1 Hernández-Molina, Francisco Javier A2 Física Aplicada AB Global circulation of intermediate water masseshas been extensively studied; however, its regional and localcirculation along continental margins and variability and implicationson sea floor morphologies are still not well known.In this study the intermediate water mass variability in theGulf of Cádiz (GoC) and adjacent areas has been analysedand its implications discussed. Remarkable seasonal variationsof the Antarctic Intermediate Water (AAIW) and theSubarctic Intermediate Water (SAIW) are determined. Duringautumn a greater presence of the AAIW seems to berelated to a reduction in the presence of SAIW and EasternNorth Atlantic Central Water (ENACW). This interactionalso affects the Mediterranean Water (MW), which ispushed by the AAIW toward the upper continental slope. Inthe rest of the seasons, the SAIW is the predominant watermass reducing the presence of the AAIW. This seasonalvariability for the predominance of these intermediate watermasses is explained in terms of the concatenation of severalwind-driven processes acting during the different seasons.Our finding is important for a better understandingof regional intermediate water mass variability with implicationsin the Atlantic Meridional Overturning Circulation(AMOC), but further research is needed in order to decodetheir changes during the geological past and their role, especiallyrelated to the AAIW, in controlling both the morphologyand the sedimentation along the continental slopes.
