MARC recordArctic Ocean noise generation due to pack ice kinematics and heat fluxes / James K. Lewis, Warren W. Denner.
| Title: | Arctic Ocean noise generation due to pack ice kinematics and heat fluxes / James K. Lewis, Warren W. Denner. |

| In: | Sea surface sound; natural mechanisms of surface generated noise in the ocean. (1988.), |
| Abstract: | During summer, most under-ice noise is generated by ice rushing through water, In autumn, total deformation of pack ice becomes important in producing lower frequency noise (10 and 32 Hz). Correlations indicate that differential motions of other forms (primarily ice convergence) become important only during winter. For higher frequency noise (1000 Hz) during autumn and winter, correlations with ice motion are low and ambiguous. Generation of higher frequency noise by combination of ice and thermal fracturing may be cause of sporadic nature of frequency band. Anomalous observations are presented, which are investigated using various environmental data sets. Model of thermal heat flux within ice slab is used to demonstrate character of one set of observations. However, there are distinct deficiencies in that model fails to reproduce phase of thermal microfracturing and certain periods during which microfracturing is absent. |
