Some Features of Sound Behavior in Relation to Thermal and Salinity Structure in the North Pacific.
Abstract
The purpose of these brief notes is (1) to facilitate the interpretation of some oceanographic analyses and prediction charts already issued or in preparation by FNWF, in respect to sound behavior; (2) to describe some short-term fluctuations in thermal structure (e.g., 'afternoon effect') which, because of their short duration, cannot be included in the analyses and predictions; and (3) to describe the upper sound channel, which is important in increasing surface sound transmission losses but increases considerably the propagation distances of nearly horizontal low-frequency sound at its depth.
