The occurrence of marine species outside their usual habitat has become increasingly common in various regions of the world. In Salvador (BA) and its metropolitan area, for example, the appearance of a sea lion, an animal native to cold waters, caught the attention of the population and raised concerns about the impacts of climate change on the behaviour and health/well-being of animals. This challenge aims to develop digital solutions capable of tracking and monitoring the presence of marine species, especially in environments where their presence is unusual. The goal is to cross-reference data on the oceans, climate, and scientific and popular sightings to understand behaviour patterns and possible relationships with environmental factors. As a result, it is hoped that tools will be created that are accessible to scientists, environmental managers and the civil community, encouraging the strengthening of conservation actions, understanding of the environmental impacts on marine species and promoting the use of accessible and collaborative science.
