Acoustic Communications and Navigation for Mobile Under-Ice Sensors

Abstract

The long-term goals of this project are to create a new capability for under-ice acoustic navigation and communication, specifically in support of the ONR Marginal Ice Zone (MIZ) Departmental Research Initiative (DRI). The MIZ DRI field program will occur in 2014, with trials starting in 2013. The MIZ DRI will include a large array of sensors deployed on the surface of the ice, as well as Sea Gliders and drifters operating below. The project seeks to answer a number of important science questions, and will investigate surface forcing, both mechanical and solar, on the ice and the upper water column. The response of the upper ocean will be established using data collected sub-sea by the autonomous vehicles operating under the ice, and then assimilated into oceanographic models.
