Strandings of marine mammals, sea turtles and seabirds along central Santa Catarina 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 Santa Catarina state’s central coast, from
27°23'7.357" S 48°26'2.519" W to
27°50'24.231" S 48°33'48.706" W. During this period,
5497 animals of 46 species were recorded, 86.90% of which were dead and
13.10% 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.
