Acoustic Thermometry of Ocean Climate

Quick Reference


An experiment to measure oceanic temperatures by determining the time for sound to travel from acoustic sources off California and Kauai (in the Hawaiian Islands) to hydrophones at various sites across the Pacific Ocean. The velocity of sound increases with water temperature, which the method should determine to within 0.05–0.1 deg C. It is potentially a sensitive method of monitoring global warming.
