This dataset comprises occurrence records of live and dead strandings of the American manatees (Trichechus manatus) recorded along the coast of Ceará State, northeastern Brazil, by Aquasis. The records originate from systematic monitoring, rescue activities, and reports from the public and partner institutions. The dataset provides georeferenced information on stranded individuals and associated biological and event data, contributing to biodiversity knowledge, conservation, and the long-term monitoring of one of the most threatened marine mammal species in Brazil.

This lack of accessible data limits its inclusion in national action plans and weakens regional conservation planning for marine mammals in South America. The need for manatee data was identified during coordinated data-mapping efforts in 2023, led by Dr. Carol Meirelles through the Alliance for Manatees. These efforts revealed large data gaps despite the existence of records from universities, NGOs and government agencies.\n\nThis project standardizes and publishes legacy datasets compiled from 19 institutions and integrates new data collected across 2024 and 2025. The delivery of a regional workshop in Suriname, where manatee data is critically lacking, provides essential training for participants in data mobilization. Training associated with this project covers Darwin Core formatting, metadata preparation and publishing to GBIF. It will be delivered in partnership with GBIF Brazil (SiBBr), ensuring hands-on guidance from data experts. The project also produces a multilingual technical guide based on case studies, enabling replication and long-term sustainability of best practices.\n\nBy bridging knowledge gaps, promoting open-access data sharing and fostering regional collaboration, the project delivers long-term benefits for biodiversity. It provides an essential data foundation for conservation prioritization, supports environmental decision-making and ensures that aquatic mammals are integrated into national biodiversity strategies."},"samplingDescription":{"studyExtent":"The study area comprises the entire coastline of Ceará State, northeastern Brazil, extending approximately 573 km.","sampling":"American manatee strandings have been recorded along the coast of Ceará since the late 1980s.
