The Southern right whale (Eubalaena australis) is one of the most iconic species of the Argentine Patagonian coast, having been declared a Natural Monument in 1984. The species is currently in good conservation status, although its population is still less than one-tenth of what it was before the whaling industry. Every year, between June and November, these whales return to the calm waters of the northern Patagonian gulfs to mate, give birth, and care for their calves before embarking on long journeys to their feeding areas. In recent years, new technological tools have enabled satellite tracking of the species, leading to the “Following Whales” project (https://siguiendoballenas.org/), which has identified feeding areas and regions of intensive use, as well as the overlap of these areas with various human activities.
