The Great Barrier Reef Whale and Dolphin Research Programme is a collaborative project between CEAL and Blue Planet Marine collecting data on East Australian humpback whales on a largely unexplored breeding ground. This project aims to identify critical breeding areas, investigate the stock structure of this population, and explore the social communication of whales in breeding situations. Data collected includes blubber samples for hormone analysis and to obtain genetic information to explore population structure; identification photographs to determine the movement patterns of individual whales; underwater recordings of vocalisations of animals in competitive groups to explore the sound types used and the information content encoded in these sounds; focal follows of whales in groups to determine the behaviour of whales on the breeding ground; and recordings of background noise in the area to investigate the possible effects of both biological and anthropogenic noise on humpback whale communication.
