SAN DIEGO — Naval Information Warfare Systems Command (NAVWAR) joined the Swedish Defense Research Agency and the Swedish Coast Guard in Lulea, Sweden, to test how ice effects sound in the underwater domain March 11-23.
As part of an ongoing program with Swedish authorities, personnel from the NAVWAR Reserve Program (NWRP) and Naval Information Warfare Center Pacific (NIWC Pacific) Unmanned Maritime Vehicle (UMV) Lab teamed to support the event.
NWRP Sailors and NIWC Pacific engineers utilized various sensors, magnetometers and a Seabotix vLBV, a remotely operated vehicle (ROV), to identify the potential impact of ice on sound propagation and background noise underwater.
NWRP Sailors operated the ROV to test acoustic transceivers and collect sonar and video imagery of the conditions beneath the ice and to provide logistic mission support with programming magnetometers.
“Sonar and camera data from the ROV provided insight into the structure of the ice,” said Tom Pastore, a NIWC Pacific engineer. “Simultaneous acoustic measurement data between various fixed points will allow researchers to characterize the impact of ice-covered waters as compared to an open surface. This is an important addition to the scientific body of knowledge and leads us towards better modeling capability in under-ice regions.”
The collective team from NAVWAR and Sweden have a second trial scheduled for first quarter of fiscal year 2020.
NWRP Sailors leverage their education, corporate knowledge and military experience and apply those skills to UMV and other technology testing events to address potential challenges with respect to complex command, control, communications, computer and intelligence systems.
“NAVWAR Reservists provide manpower with diverse technical and operational skill sets, enabling the sponsor to successfully complete the mission no matter the challenges,” said Thomas McDermott, NWRP UMV program manager.
