Acoustic research (the science of how sound is transmitted) increases our understanding of whale, dolphin, and fish behavior as well as the environmental soundscape; and enables the development of better methods to locate cetaceans using autonomous gliders and passive acoustic arrays. Additionally, since sperm whales spend long periods (typically up to 10 minutes) “rafting” at the surface between deep dives, they are more vulnerable to vessel strikes. Sperm whales are the largest toothed whale, have the largest brain of … Our scientists collect information and present these data in, NOAA conducts research on the acoustic behavior of cetaceans, including sperm whales. Acoustics are used to monitor hearing levels and feeding behavior in sperm whales. Sperm whales have been tagged in an effort to learn more about foraging behavior, movement patterns, and core home ranges. Unlike females, puberty in males is prolonged, and may last between the ages of 10 to 20 years old.
