Global Foundation for Ocean Exploration engineers Lars Murphy and Sean Keninson prepare the USBL (ultra-short baseline) transponder for calibration. The USBL system is used to determine the position of remotely operated vehicles Deep Discoverer and Seirios while the vehicles are in the water. The calibration was designed to maximize the accuracy of the system. Learn more about USBL calibration.
