Abstract: The Santos Basin Beach Monitoring Project (Projeto de Monitoramento de Praias da Bacia de Santos - PMP-BS) is one of the monitoring programs required by Brazil's federal environmental agency, IBAMA, for the environmental licensing process of oil production and transport by Petrobras at the pre-salt province (25⁰05'S 42⁰35'W a 25⁰55'S 43⁰34'W), between 2100m and 2300m isobaths. To evaluate the possible impacts of these activities on marine turtles, marine mammals, and seabirds, the main activity of the PMP-BS is to monitor daily approximately 1040km of coastline. The project started on August-2015 and is scheduled to continue for at least three more years. As results of the beach survey effort, 34089 seabirds have been found on the beaches, from August 2015 to August 2019. The Bird Family with more individuals was Spheniscidae with 17134 animals, followed by Procellaridae with 6632 and Laridae with 3632. Considering Species, the most common were 17,126 Spheniscus magellanicus, followed by 4610 Puffinus puffinus, 2981 Larus dominicanus and 1123 Thalassarche chlororhyncos. At macroscopic exam, 2247 animals had signs of anthropogenic interaction. That is only a small fraction of animals that die at sea arrive on the coast, the high number of seabirds observed during beach monitoring imply in very high mortalities at sea.
