Australian Humpback Whales and Ambient Noise
The goal of the Humpback Acoustic Research Collaboration (HARC) is to understand the behavioral responses of large marine mammals to their surrounding acoustic environment. The fundamental thesis of the HARC project is that the effects of ambient ocean noise from natural and anthropogenic sources on...

The goal of the Humpback Acoustic Research Collaboration (HARC) is to understand the behavioral responses of large marine mammals to their surrounding acoustic environment. The fundamental thesis of the HARC project is that the effects of ambient ocean noise from natural and anthropogenic sources on baleen whales (Humpback, Megaptera novaeangliae) can be deduced by making careful observations in the presence and absence of sound. Visual observations from land and surface vessels are coordinated with subsurface tracking of singing whales using hydrophone arrays. Detailed observations of individual whale behavior are made using sophisticated digital tags attached by suction cup to selected individuals to compliment the observations of pods and populations. The detailed structure of the ambient noise field, physical oceanography, and meteorology in the study site are characterized to define the physical acoustics of the environment.
