Map of the Southern Ocean feeding grounds from Culturally transmitted song exchange between humpback whales (Megaptera novaeangliae) in the southeast Atlantic and southwest Indian Ocean basins

Figure S1. Map of the Southern Ocean feeding grounds (adapted from Amaral et al. 2016). The feeding grounds are divided into six management areas by the IWC that correspond with the seven Southern Hemisphere breeding stocks. Study sites are represented by a star symbol and correspond with the appropriate population level demarcation.
