Prepared for: The Office of Naval Research, Code 32 The Arctic Exercise 2023 (ARCEX23) Cryophone Experiment was funded by ONR Code 32 (Battlespace Environments). The experiment was conducted during March 5-9 on Lake Colleen in Prudhoe Bay and on first year sea ice 180 nm north of Prudhoe Bay during March 10-11. Both environmental and acoustical data were collected with a focus on acoustical wave propagation through three media (water, ice, and air). This report documents the equipment used by the Naval Postgraduate School (NPS) during the study and details initial findings. The initial findings suggest cryophones can be used to detect signals below and above the ice, providing 360 degrees of detection. Final results will be published in future peer-reviewed scientific journals. Approved for public release; distribution is unlimited.
