Description
This postdoctoral fellowship opportunity at the Naval Research Laboratory (NRL) in Washington, DC focuses on advancing physics-informed, passive acoustic methods to study regional oceanography. The research leverages data-driven, through-the-sensor signal processing techniques that exploit the dominant acoustic energy emitted by uncontrolled, broadband surface vessels. These acoustic sources serve as "sources of opportunity" to estimate key environmental parameters such as sea-floor depth, bottom sediment properties, and the sound speed profile in the water column.
Near-term research goals include understanding the information content of ambient noise, identifying influential oceanographic processes, characterizing source dynamics, and optimizing sensor configurations. Long-term objectives involve developing data-assimilation models, including Bayesian approaches, to improve environmental parameter estimation.
This fellowship is ideal for researchers interested in acoustics, signal processing, oceanography, inverse theory, physics, and machine learning applied to environmental sensing.
