             abstract = "Water transformation at the Weddell Sea margins links the upper 
                         and lower limbs of Meridional Overturning Circulation by means of 
                         dense water formation, which may be affected by rapid climate 
                         change. Warm Deep Water (WDW) is the primary heat source for the 
                         Weddell Sea and accounts for 71% of Weddell Sea Bottom Water 
                         (WSBW), which is the regional variety of Antarctic Bottom Water 
                         (AABW) - one of the densest water masses in the ocean bearing 
                         directly on the global ocean bottom ventilation. In this 
                         presentation we will examine WDW evolution simulated by the 
                         Brazilian Earth System Model (BESM) in a 21th century projection 
                         compared to four realistic CMIP5 models (ESMs). Salinity and 
                         temperature results from a cross-section in the Weddell Sea were 
                         assessed with the Optimum Multiparameter Analysis (OMP) water 
                         masses separation scheme. Results show a shoaling trend of WDW who 
                         becomes lighter throughout the simulation period. This is likely 
                         to increase the onshore heat transport with potential impacts to 
                         AABW formation and export from the Weddell Sea. Moreover, these 
                         trends might also increase ice shelf basal melting, ice sheet 
                         retreat and eventually sea level rise.",
