The possible use of long‐range acoustic propagation as a tool for measuring oceanographic processes has tantalized the oceanographic community for 15 years. During this period a growing number of oceanographers joined teams to acoustically measure the fields of sound speed and water velocity (currents) on subocean‐basin scales and to infer from those measurements temperature, vorticity, and heat content.
