Wet sand reflecting sounds

Caption

At a North Carolina beach, researchers have been poking and prodding the sand to study how moisture levels affect sounds as they move across the environment. Over short distances, even moderately wet sand reflects sound more like water does than as a solid surface does. Faith Cobb and her team are looking into if the same is true for long-range sound propagation.
