Summary: | A great deal of controversy exists concerning the possible global warming trend which may occur as a result of a documented increase in atmospheric "greenhouse" gasses. The 1991 Heard Island Feasibility Experiment tested the feasibility of using transmissions of acoustic energy through the major ocean basins of the world to monitor spatially averaged global temperature trends. This thesis documents the Naval Postgraduate School's reception of the phase encoded signal transmitted from the Southern Indian Ocean, development of real-time signal processing software, and preliminary data analysis.
