• AUVs have proved robustness and high performance in applications including naval mine counter measures, marine research and deep water offshore oil and gas surveys. A next step is to introduce AUVs to under ice geophysical surveys. A main challenge for regular under ice operations is to handle the risk of a loss of a vehicle, or long operational interruptions. The paper discusses how to reduce this risk by careful tailoring of critical AUV subsystems. A fundamental requirement is to apply a robust, well designed and well proven vehicle, continually upgraded from field experiences. Another main challenge is to design a sensor suite that allows for cost efficient and fast mapping of the vast areas under ice. A geophysical sensor suite is presented and solutions for high area coverage rates examined.
