About

Anthony Spears is a pioneering polar roboticist whose work focuses on the development and deployment of autonomous underwater vehicles (AUVs) for extreme environment exploration, particularly beneath Antarctic ice shelves and glaciers. His major contributions center on the Icefin unmanned underwater vehicle, which he helped design and operate to access some of the most inaccessible regions on Earth. Spears led the first long-range robotic exploration of the grounding zone of Thwaites Glacier in 2020, a landmark achievement that provided unprecedented direct observations of a critical area driving sea-level rise. His most cited work, "Under Ice in Antarctica: The Icefin Unmanned Underwater Vehicle Development and Deployment" (2016, 58 citations), established the foundational technology and methodology for under-ice robotic exploration. Spears also developed a robust compact water sampler for underwater vehicles, enabling discrete sample collection in high-pressure, low-temperature environments. His work has fundamentally advanced our understanding of ice-ocean interactions at the Antarctic margin, directly informing climate models and future planetary exploration missions.
