Ice Geochemical Observation

Ice geochemical observation focuses on acquiring data from challenging sub-ice environments, primarily to understand processes influencing climate change, such as greenhouse gas fluxes and ocean dynamics. Current research emphasizes developing advanced robotic platforms—including autonomous and remotely operated vehicles—equipped with sophisticated navigation systems (e.g., integrating visual, inertial, and Doppler velocity log data using Kalman filtering techniques) to enable precise data collection in these harsh conditions. These advancements are crucial for improving models of sea level rise, ocean circulation, and carbon cycling, ultimately contributing to a more accurate understanding of climate change impacts.
