National Park of American Samoa
Housed in a titanium pressure case anchored to the ocean floor 110 ft. deep off Tutuila Island, a hydrophone logs incoming signals from humpback whales. Located in turquoise waters in the heart of the South Pacific, the park is a thoroughfare for migrating marine life such as whales. Humpbacks seek the warm, South Pacific waters in late fall and early winter to mate and give birth. They rely on sound to communicate with one another and detect vital environmental cues. Their calls are among many different recorded sounds that are sampled and analyzed by scientists each year. The recordings help scientists identify species presence and seasonal patterns of activity of both marine life and humans.
