             abstract = "The western region of the South Atlantic Ocean is highly complex 
                         in terms of ocean circulation, water masses formation and mixing 
                         both at the open ocean and at the coast. The open ocean is 
                         modulated by strong mesoscale variability, mainly dominated by the 
                         Brazil Current (BC) and the Malvinas/Falkland Current (MC) at 
                         their meeting region known as the Brazil-Malvinas Confluence 
                         (BMC). These currents are characterized by high temporal and 
                         spatial variability of the transport, sea surface temperature 
                         (SST), chlorophyll concentration and sea surface height. As part 
                         of the Brazilian Antarctic Program (PROANTAR), simultaneous in 
                         situ measurements of the Atmospheric and Oceanic Boundary Layers 
                         (MABL and OBL) are continuously performed at the Brazil- Malvinas 
                         Confluence region (BMC) since 2004. The BMC region is known as one 
                         of the most energetic regions of the World Ocean presenting very 
                         strong thermal gradients between the meeting waters of the warm 
                         Brazil Current (BC) and the cold Malvinas Current (MC). The in 
                         situ experiments were inspired by previous works where the air-sea 
                         coupling was investigated in the Equatorial Pacific (Hashizume et 
                         al., 2002), Agulhas Current return flow regions (Rouault et al., 
                         2000) and in the BMC region itself (Pezzi et al. 2005; Tokinaga et 
                         al. 2005). All these regions are subject to high thermal and/or 
                         sea level contrasts owing to the presence of Tropical Instability 
                         Waves (TIW), oceanographic fronts and mesoscale features such as 
                         meanders or eddies. Four experiments were conducted onboard OSS 
                         Ary Rongel. While crossing the BMC front, profiles of water 
                         temperature and atmospheric parameters were made. Using data from 
                         2004, Pezzi et al. (2005) demonstrated that the MABL was directly 
                         modulated by the very strong surface thermal gradients between the 
                         warm waters of the BC and cold waters of the MC. To our knowledge, 
                         simultaneous descriptions of the MABLOBL synoptic conditions at 
                         BMC are very rare. This work presents an original description of 
                         the MABL and OBL structure as well as the air-sea coupling at the 
                         BMC region based on in situ data collected during four INTERCONF 
                         cruises that took place during specific dates in the Austral 
                         spring from 2004 to 2007.",
