2015 Nancy Foster Sonar Acceptance Report

Vessel: R/V Nancy Foster
Multibeam System: EM710
Dates: March 9-13, 2015

A Kongsberg EM710 MKII multibeam was installed aboard NOAA Ship Nancy Foster at GMD Shipyard in Brooklyn, NY in March of 2015. This system replaced the antiquated EM1002 and is the third EM710 installed on a NOAA ship. The MKII EM710 has an extended frequency range that increases the effective depth range of the system. This installation was the second MKII system delivered by Kongsberg in the United States. An unrealistic fabrication and installation period and associated shipyard delays complicated the installation of this system. Shortened sea acceptance trials were conducted during the transit to Charleston, SC. Nancy Foster was underway from NY on March 9, and arrived in Charleston on March 13. The last two days were entirely dedicated to transit in poor weather.
