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

description: 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. 
description: Stranding records were
 collected along the coast of Santa Catarina and Paraná states, from
 28°8'37.56"S / 48°38'42.37"O to
 25°58'31.35"S / 48°35'45.61"O. According to their
 accessibility, each beach had a predefined sampling strategy that was
 maintained during the project. Beaches were monitored either daily (335.9 Km)
 or weekly (113.1 Km), preferentially in the morning. Additionally, a
 toll-free number was made available, so the local population could inform
 the institution responsible for the sector if an animal stranded after the
 field team monitored the area. Some beaches in the area (177.6 Km) were
 not monitored regularly, and animals on them were collected only when
 there were calls from the public. Records made during regular monitoring
 or by calls from the local population are identified separately in the
 data. All animals observed during beach surveys were
 recorded. Depending on the carcasses’ decomposition stage, they were
 either disposed of or taken to the laboratory for necropsy. Sex and
 development stage were identified using external characters or by direct
 examination of gonads during necropsy. 
 Taxonomic identification was
 usually done using morphologic characters, but when this was not possible
 due to decomposition or predation, a molecular analysis was performed, by
 sequencing the COI gene and identification of the species using the
 Barcode of Life Data System (Ratnasingham & Hebert, 2007).
 Taxonomical classification follows the taxa retrieved from the Integrated
 Taxonomic Information System (ITIS) (http://www.itis.gov) on March 2016. Animals were collected under IBAMA's license ABIO 640/2015.

 Catarina from August 2018 to August 2023
 This dataset includes
 records of stranded marine mammals, sea turtles and seabirds along the
 Paraná and Santa Catarina coasts, from 2018-08-24 to 2023-08-31, by the
 Santos Basin Beach Monitoring Program (“Programa de Monitoramento de
 Praias da Bacia de Santos” - PMP-BS). Most beaches were monitored either
 daily or weekly, but on some beaches, animals were collected only when the
 local community informed the project. This project is part of the
 environmental licensing process led by the Brazilian environmental agency
 (IBAMA), for the oil and gas production in deep waters of the Santos Basin
 by PETROBRAS, the main oil company operating in the basin. All animals
 were collected under license ABIO 640/2015, issued by IBAMA. Beach
 monitoring during this period is performed by the following institutions
 (south to north): UDESC, Instituto Australis, Associação R3 Animal,
 UNIVALI, UNIVILLE, and UFPR. UNIVALI is the institution responsible for
 the coordination of the PMP-BS in this area. ## Description of the data
 and file structure The data includes the following descriptors:
 **Individual Identifier** - unique identifier for the record at the SIMBA
 database () **Occurrence
 Identifier** - 20-digit identifier **State, County, Beach** - Names of the
 location where the animal was found **Monitoring strategy** - Daily,
 weekly, 'community call' **Date/time** - using ISO 8601 format.
 Local time when the animal was observed by the survey team. **Latitude,
 Longitude** - collected on the beach with portable GPS, using WGS84 datum
 (EPSG:4326). **Animal condition** - condition of the animal when it was
 first observed (dead / alive) **Class, Order, Suborder, Family, Genus,
 Species** (Taxonomical identification) - identified to the most detailed
 level **Developmental stage** - adult / juvenile / young / fetus /
 unknown. Fetuses were recorded separately when observed during the
 necropsy of marine mammals. **Sex** - male / female / unknown ##
 Sharing/Access information Data collected by the PMP-BS is deposited at
 the 'Sistema de Informação da Biota Aquática' - SIMBA, and can
