The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a Scientific Committee for
Antarctic Research project led jointly by the Expert Groups on Birds and Marine Mammals and
Antarctic Biodiversity Informatics, and endorsed by the Commission for the Conservation of
Antarctic Marine Living Resources. RAATD consolidated tracking data for multiple species
of Antarctic meso- and top-predators to identify Areas of Ecological Significance. These
datasets and accompanying syntheses provide a greater understanding of fundamental
ecosystem processes in the Southern Ocean, support modelling of predator distributions
under future climate scenarios and create inputs that can be incorporated into decision
making processes by management authorities. In this data paper, we present the compiled
tracking data from research groups that have worked in the Antarctic since the 1990s. The
data are publicly available through biodiversity.aq and the Ocean Biogeographic Information
System. The archive includes tracking data from over 70 contributors across 12 national
Antarctic programs, and includes data from 17 predator species, 4060 individual animals, and
over 2.9 million observed locations.
