NJIT Mathematician Uses Navy Grant To Map Earth Ocean Floor With Underwater Sound Waves

Eliza Michalopoulou, a mathematics professor at New Jersey Institute of Technology (NJIT), is leading research funded by the Office of Naval Research (ONR) to improve underwater mapping techniques using sound waves. Despite significant advancements in space exploration, nearly 75% of Earth’s ocean floor remains unmapped in high resolution due to extreme conditions such as crushing pressure and low temperatures.

Michalopoulou’s project focuses on analyzing how physical properties of the ocean influence sound propagation, employing mathematical models to transform underwater sound data into detailed seafloor information. This research addresses challenges in interpreting acoustic data, which can yield conflicting results depending on assumptions about oceanographic conditions and sediment properties.

By simulating realistic underwater environments, Michalopoulou aims to evaluate different mapping methods for accuracy and consistency, with potential applications in anti-submarine warfare and environmental conservation. Her work aligns with broader global initiatives like the Seabed 2030 project and UNESCO’s Ocean Decade, contributing to efforts to better understand Earth’s least explored frontier.

The Terrestrial Blind Spot: Earth’s Unmapped Ocean Floor

The ocean floor remains one of Earth’s least explored frontiers, with nearly 75% unmapped in high resolution despite extensive knowledge about Mars. Eliza Michalopoulou’s research at NJIT focuses on leveraging underwater sound waves to map the ocean floor remotely, avoiding the extreme conditions of deep-sea environments such as high pressure and low temperatures.

The complexity of interpreting acoustic data under varying environmental conditions presents significant challenges. Michalopoulou employs advanced mathematical models to simulate real-world scenarios, identifying sources of uncertainty in geoacoustic inversion techniques. By evaluating the accuracy and consistency of these methods, her work aims to improve the reliability of ocean floor mapping data. This approach addresses noise interference and variable oceanographic conditions, which further complicate underwater mapping efforts.

The interaction between sound waves and sediment composition is a critical factor in determining seafloor characteristics. Michalopoulou’s research integrates acoustic data with computational models to better understand these dynamics, offering insights into optimizing sound propagation for precise seafloor characterization. This work is essential for advancing our ability to map unexplored regions of the ocean floor with greater accuracy and consistency.
