• In preparation for experimental work in the Arabian Sea, geoacoustic models 

 were furnished for four stations to allow predictions of underwater sound propagation 

 in the area. These models were part of the predictive study issued by the Naval Ocean 

 Systems Center as TN 104 (Northrop et al, 1977). A portion of this report (Northrop 

 et al, 1978) is in press as an article for the Journal of Underwater Acoustics.
