THE TRANSITION FROM MOVING TO FAST ICE IN WESTERN VISCOUNT MELVILLE SOUND

An unexpected result of the recording of underwater noise under sea-ice is the ability to detect the difference in character of the noise generated by ice in motion in relation to the noise generated under shore-fast ice. The detection of motion was easily made by observing the hourly samples of und...

Description
Summary:An unexpected result of the recording of underwater noise under sea-ice is the ability to detect the difference in character of the noise generated by ice in motion in relation to the noise generated under shore-fast ice. The detection of motion was easily made by observing the hourly samples of underwater noise recorded by a remote instrument package (RIP). One RIP was installed in the sea bottom south of Melville Island in August 1967 and was recovered one year later. A sample strip-chart record of the change of underwater noise-power with time in the 150-300 Hz frequency band is shown. (Author)
