Description
Summary:This report details the kinetic analysis of sea ice motion data collected during the Arctic Ice Dynamics Joint Experiment (AIDJEX) in the Beaufort Sea. In addition, relationships between the ice kinematic parameters and associated ambient noise are presented. These relationships were determined by an extensive correlation process between the noise and ice motion time histories. Time scales of the various modes of ice motion were calculated by season. Also, seasonal time and space scales were calculated for ambient noise at 10 Hz, 32 Hz, and 1000 Hz. Contents of this section include: Seasonal Arctic Ambient Noise Temporal Autocorrelations, Beaufort Sea, 1975-1976; Seasonal Arctic Ambient Noise Spatial Autocorrelations, Beaufort Sea, 1975-1976; Seasonal Arctic Ambient Noise Power Spectra, Beaufort Sea, 1975-1976. Keywords: Lagrangian data; Thermal cracking. See also Parts 1 and 2, AD-A165 303.
