Abstract

A low frequency sound propagation experiment was conducted in the Western Barents Sea from a towed continuous sound source and air-dropped explosive sound sources to a hydrophone lying on the sea bed. Anomalies in the propagation results were traced to sub-bottom features, in particular to a region of basement outcrop. This paper will present data suggesting the influence of a particular salt diapir occurring within this basement outcrop region upon the low frequency sound propagation. The results suggest alternative interpretations for the mechanism of influence of the sea-bed upon the sound field.
