title: Strandings of marine mammals, sea turtles and seabirds along the central-north São Paulo coast, Brazil, from 2015 to 2018.

description: 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 central-north São Paulo state coastline, from
 23°45'24.183" S 45°50'23.129" W and
 23°59'56.029" S 46°23'30.836" W. During this period,
 3347 animals of 52 species were recorded, 76.82% of which were dead and
 23.18% 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.
description: This dataset represents the records of stranded animals made at
 PMP-BS’ Sector 9 (23°45’24.183” S 45°50’23.129” W and 23°59’56.029” S
 46°23’30.836” W), in the state of São Paulo, including beaches at the
 Bertioga, Guarujá, Santos and São Vicente counties. The surveyed area
 includes 26 beaches, with a total extent of 59.24 Km. Beaches were
 monitored either daily (58.91 Km) or weekly (0.33 Km), preferentially in
 the morning. Additionally, a toll-free number was made available, so that
 local communities could inform of stranded animals. Records made during
 regular monitoring or by calls from the local public are separately
 identified in the data. The
 data presented here describe animals recorded from 1 September 2015 to 31
 August 2018. All animals observed during beach surveys were recorded.
 Depending on the decomposition stage, carcasses were either disposed of,
 or taken to the laboratory for necropsy. Animals that stranded alive and
 needed veterinary treatment were taken to rehabilitation centers
 maintained by the institutions part of the PMP-BS. Sex, development and
 maturation stage were identified using external characters or by direct
 examination of gonads during necropsy. All recovered carcasses were
 submitted to biometry. For fresh carcasses, samples were collected for
 histopathological analysis, natural history and any other analyses needed
 to identify the cause of
 death. Taxonomic identification was usually done using morphologic characters, but when this was not possible owing to decomposition or predation, a molecular analysis was performed, by sequencing the COI gene and identification the species using the Barcode of Life Data System. Taxonomical classification follows the taxa retrieved from the Integrated Taxonomic Information System (ITIS) (http://www.itis.gov) on March 2016. Specimens were collected under permit “ABIO No. 640/2015” from <i>Instituto Brasileiro do Meio Ambiente e Recursos Naturais Renováveis – IBAMA</i>.
description: This dataset presents part of the data generated by the Santos
 Basin Beach Monitoring Project (PMP-BS, from “Projeto de Monitoramento de
 Praias da Bacia de Santos”), which aims to evaluate the potential impacts
 from oil and gas production at the oceanic Pre-Salt province on Brazil’s
 Santos Basin. This project was required by the federal environmental
 agency in Brazil (IBAMA), as part of the environmental licensing of
 PETROBRAS’ activities in the area, together with other monitoring programs
 (further information can be obtained at http://www.comunicabaciadesantos.com.br). The PMP-BS focuses on beached seabirds, sea turtles and marine mammals, as requested by the environmental agency. Due to the large extension of the monitored area (&gt; 1,000Km), it was divided in 15 ‘sectors’, that were under the responsibility of different institutions and data from each sector are being reported in separate data papers. To guarantee that data was collected homogeneously, all institutions followed the same field protocols (available at http://www.comunicabaciadesantos.com.br), which were based on national and international protocols. A central data repository has been developed (“Sistema de Monitoramento da Biota Aquática – SIMBA”), allowing for the standardization and organization of all data generated by the PMP-BS, linking data obtained at the field to laboratory analyses. <strong>Resources in Dryad</strong>:<br> <br> Strandings of marine mammals, sea turtles and seabirds along the South Santa Catarina state coastline, from 2015 to 2018.
