Oceanographic and biological landscapes used by the Southern Giant Petrel during the breeding season at the Patagonian Shelf

The study of how and why marine animals distribute themselves at sea has important conservation and management implications of the species and their habitats. We characterize the oceanographic and biological landscapes of the marine areas used by breeding Southern Giant Petrels (Macronectes giganteu...
