Acoustic study reveals deep-diving behavior of elusive beaked whales

Scientists have captured a rare view of one of the ocean's least understood whales—without ever seeing it. By listening to the sounds beaked whales naturally produce, researchers have reconstructed a three-dimensional picture of their deep-diving behavior in the Gulf of Mexico. The study provides the first detailed description of the deep-diving behavior of a Gervais's beaked whale (Mesoplodon europaeus) anywhere in the world.
