Monitoring ice accumulation for surface ships traveling in the Arctic
PI: Dr. Christopher J. Earls. Cornell University. Sponsored by the Office of Naval Research (ONR).
Develop stochastic inversion framework for monitoring evolving surface ship mass properties during Arctic operations
Establish proof of concept for framework, demonstrated at both full-scale and 1:23 model-scale. Framework utilizes existing on-board ship telemetry and validated sea-keeping software
Exercise the framework for various ice configurations at model-scale, for a single variable and multi-variable inversion scenarios
Implement computer vision algorithm to determine incoming ocean wave time history and infer forces on a ship at sea in near real time
