Stranded marine mammals, sea turtles and seabirds in Paraná and Santa Catarina from August 2018 to August 2023

To assess the potential impacts from oil and gas production in deep waters
of Brazil’s Santos Basin, the Brazilian environmental agency (IBAMA)
required PETROBRAS, the main oil company in the basin, to implement the
“Projeto de Monitoramento de Praias da Bacia de Santos” (Santos Basin
Beach Monitoring Project - PMP-BS). This project has been operating along
the states of Santa Catarina, Paraná, São Paulo, and Rio de Janeiro, since
August 2015, collecting data from stranded seabirds, turtles, and marine
mammals. This dataset includes records from August 2018 to August 2023,
along the Paraná and Santa Catarina coastlines. During this period, 58151
animals of at least 93 species were recorded (883 unidentified animals).
From this total, 88.6% were dead and 11.4% alive when first observed. This
dataset complements previous ones from the same area, and is a
high-intensity monitoring effort essential to understand temporal and
geographical variation of stranded animals. This data will allow future
works aimed at understanding the impacts of human activities on marine
ecosystems and environmental changes over time.
