Sketch showing where very precise studies of the sound velocity structure of the ocean was conducted by the C&GS ships PIONEER and GUIDE in 1933. These studies were conducted to better understand the sound velocity structure for use with the radio acoustic ranging navigation system. Understanding of both reflection and refraction of sound in the ocean resulted from these experiments.
