             abstract = "The Brazil Current (BC) is a weak western boundary current fowing 
                         along the Southwestern Atlantic Ocean. It is frequently described 
                         as a fow with intense mesoscale activity and relatively low volume 
                         transport between 5.0 and 10.0 Sv. We use a 13-year eddy-resolving 
                         primitive-equation simulation to show that the presence of 
                         persistent meanders and eddies leads to characteristic 
                         quasi-steady Lagrangian transport patterns, aptly extracted 
                         through climatological Lagrangian Coherent Structures (cLCS). The 
                         cLCS position the surface expression of the BC core along the 
                         2000-m isobath, in excellent visual agreement with high resolution 
                         satellite sea-surface temperature and the model Eulerian mean 
                         velocity. The cLCS deformation pattern also responds to zonally 
                         persistent cross-shelf SSH transition from positive (high) values 
                         near coastline to low (negative) values between 200- and 2000-m 
                         and back to positive (high) ofshore from the 2000-m isobath. 
                         Zonally-paired cyclonic and anticyclonic structures are embedded 
                         in this transition, also causing the cLCS to deform into chevrons. 
                         An efcient transport barrier is identifed close to the 200-m 
                         isobath confrmed by limited inshore movement of drogued drifters 
                         and accurately indicated by an along slope maxima of 
                         climatological strength of attraction. We also show that the 
                         persistent cyclonic and anticyclonic structures may induce 
                         localized cross-shelf transport. Regions of low climatological 
                         strength of attraction coincide with large shelves and with 
                         stagnant synthetic trajectories. We also show that cLCS accurately 
                         depict trajectories initiated at the location of Chevrons spill 
                         (November 2011) as compared to synthetic and satellite-tracked 
                         trajectories, and the outline of the oil from that accident. There 
                         is also an agreement between the large-scale oil slicks reaching 
                         the Brazilian beaches (from August 2019 to February 2020) and the 
                         strength of climatological attraction at the coast. Our work also 
                         clarifes the infuence of persistent mesoscale structures on the 
                         regional circulation. The identifcation and quantitative 
                         description of climatological Lagrangian coherent structures is 
                         expected to improve the efectiveness of future emergency response 
                         to oil spills, contingency planning, rescue operations, larval and
