| Pioneer Seamount was the site of one of the powerful acoustic sound sources used in the ATOC experiment, designed to measure the average temperature of the Pacific Ocean to a precision of 0.005 oC. The first phase of this experiment was completed in 1997, and the sound source and underwater cable were scheduled to be removed. However, a last-minute appeal to keep the cable in place was granted. The source was disconnected, and a vertical linear array (VLA) of hydrophones replaced it. The cable is now dedicated to monitoring the underwater environment with passive acoustic devices only. |
