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 occurred this year, 2014, and the data collected will be analyzed over the next two years. The MIZ DRI includes 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, including 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 by the autonomous vehicles operating under the ice, and the data will be assimilated into oceanographic models.
