                         Commission (BR-1) marked the Brazilian oceanography as the first 
                         effort made by Brazil to take in situ measurements over the South 
                         Atlantic Ocean in the large scale. The field campaign was 
                         undertaken along the 20oS and 30oS parallels between Brazil and 
                         Africa over the Subtropical Front (STF) using two dedicated 
                         research vessels. The first leg of the BR-1 campaign was performed 
                         between 16 October to 19 November 2009 using the new Research 
                         Vessel Cruzeiro do Sul. As part of the Brazilian Antarctic Program 
                         (PROANTAR) the Oceanographic Support Ship Ary Rongel was deployed 
                         in the Brazil-Malvinas Confluence (BMC) region in the Southwestern 
                         Atlantic Ocean between 2 and 4 November 2009 as part of the 28th 
                         Brazilian Antarctic Operation (OP28). Several oceanographic 
                         stations were made by both the BR-1 and the OP28 including the 
                         deployment of radiossondes and Expandable Bathy-Thermographs 
                         (XBTs) along the 30oS parallel and at the BMC region. These 
                         deployments aimed the study of the ocean-atmosphere interaction in 
                         the South Atlantic. The results presented here describe the 
                         interaction of the atmosphere with oceanic mesoscale structures 
                         present in the BMC region and in along the STF. The interaction 
                         occurs at the synoptic scale were a clear modulation of the 
                         atmospheric boundary layer is seen when typical structures of the 
                         BMC and the FST such as eddies and meanders are present. The 
                         atmosphere, when over the influence of the warm core (mesoscale) 
                         eddies shed by the Brazil Current in the BMC region, can receive 
                         from the ocean a latent heat flux of about 230 W.m-2. The sensible 
                         heat flux over these warm core eddies are about 10 times less 
                         intense than the latent fluxes, being sometimes even negative. 
                         Over the influence of cold structures such as the cold meanders of 
                         the South Atlantic Current in the STF, the atmosphere generally 
                         transfers heat to the ocean (negative heat fluxes). Intensities 
                         are low and could be zero. In situ observations such as those 
                         analyzed here will contribute to a better understanding of the 
                         ocean-atmosphere coupling at the mesoscale in the South Atlantic 
                         Ocean. Future benefits of this study include a better forecasting 
                         of transient atmospheric systems being formed and energized in the 
                         South Atlantic Ocean. These systems, such as the well-known 
                         Catarina Hurricane, can produce catastrophic effects over the 
                         coastal areas off Southern South America.",
