Identification of humpback whale breeding and calving habitat in the Great Barrier Reef

A predictive spatial habitat model has identified two core areas within the Great Barrier Reef Marine Park (GBRMP) that are highly probable for humpback whale occurrence during their breeding and calving season from June to September. These areas correspond with movements of satellite-tagged whales, with one likely serving as a critical wintering ground while the other appears to be a migration route. The model highlighted specific environmental parameters, such as water depth (30–58 meters, peak at 49 meters) and sea surface temperature (21–23°C, peak at 21.8°C), that define these habitats. This research is crucial for managing human interactions with whales, particularly in light of increasing coastal development and shipping activity in the GBRMP.
