| dc.description.abstract | Data from the SOMBA-GE2014 oceanographic cruise, allowed us to highlight the presence of Algerian Gyres via current measurements. The temperature and salinity sections obtained across the basin allowed the visualization of the influence of the Algerian Gyres on the hydrological distribution. Indeed, young intermediate Levantine waters extend from Saridinian LIW vein towards the interior of the Algerian Basin, in the form of patches. LIW and WIW core climatologies covering the period 1960 to 2017 in the Algerian-Provençal basin were produced using the Mediterranean database of temperature and salinity profiles and new detection methods. A westward transport of LIW from the southern vein of Sardinia to the interior of the Algerian Basin following the periphery of the Algerian Gyres is highlighted by this climatology and confirmed by the cross-correlation of the cooling signal observed during the 1980s. The estimation of trends of LIW and WIW characteristics help to document their evolution. The acceleration of warming observed throughout the basin from 2010 is alarming. Glider observations have supported our conclusions regarding the effectiveness of mesoscale andsubmesoscale structures for the transport of water masses into the interior of the Algerian Basin. Indeed, we observed WIW, LIW, and WMDW parcels within the Algerian Basin with more pronounced characteristics than adjacent waters. | |
