Strandings of marine mammals, sea turtles and seabirds along the Paraná coast, Brazil, from 2015 to 2018.

To assess the potential impacts on seabirds, turtles and marine mammals
from oil and gas production from the oceanic Pre-Salt province at Brazil’s
Santos Basin, the Brazilian environmental agency (IBAMA) required
PETROBRAS, the main oil company in the basin, to implement the “Programa
de Monitoramento de Praias da Bacia de Santos” (Santos Basin Beach
Monitoring Program - PMP-BS). Since 2015 PMP-BS has been operating along
the states of Santa Catarina, Paraná, São Paulo and Rio de Janeiro, to
collect biological data from live and dead stranded animals. This dataset
comprises the first three years of monitoring (September 2015 to August
2018) along the Paraná state coastline, from 25°18'55.314" S
48°6'20.204" W and 25°58'31.355" S
48°35'45.605" W. During this period, 6594 animals of 57 species
were recorded, 92.74% of which were dead and 7.26% alive when first
observed. This dataset represents the first high-intensity monitoring
effort in the area and is essential to establish baselines for future work
that seek to better understand the impacts of human activities on marine
ecosystems.
