Ambient noise was recorded by an eleven element hydrophone array and tape recorder beneath an ice floe during mid July 1973 in the Arctic ice pack between Greenland and Norway. Eight minute samples were taken at one hour intervals for a period of seven days. The scope of this project was to determine - if any - the dependence of spectrum and direction on environmental factors. However no dependence was found for depth, time of day, or day.
