CLASSIFICATION OF NATURAL SOUNDS IN THE UNDERWATER AMBIENT

Abstract

The identification of sounds heard in the water is very difficult. When the problem is complicated by the addition of an ice cover over the water the difficulties are often magnified and we must be very careful of attaching particular identifications to the sounds heard without good supporting evidence. The investigation of the source of often-heard 20-cps signals is cited as an example of problems encountered and how a solution and eventual identification was made.
