Sounds from a U.S. Navy SSQ-110A source are received at high signal-to-noise ratios at ocean-basin scales at two Sound Surveillance Systems in the Pacific. The sounds have sufficient pulse resolution to study climatic variations of temperature. The acoustic data can be understood using ray and parabolic approximations to the wave equation. Modeled internal waves decrease pulse resolution from 0.01 to 0.1 s, consistent with observations.
