Determination of Ice Cover Parameters Using Seismoacoustic Noise
Abstract—A method for estimating ocean ice cover parameters (thickness, Young’s modulus, Poisson ratio, and density) that does not require the use of a source is proposed and tested on experimental data. To realize the approach, two single-channel seismic receivers located on the ice surface are required to record the vertical component of the oscillatory velocity of the seismic noise. The spectral-correlation analysis of the mutual correlation function of the noise registered by the receivers allows us to estimate the dispersion dependence of the group velocity of the bending-gravity wave propagating along the ice plate. The solution of the inverse problem is based on analyzing the variance of not only the group but also the phase velocity, which allows us to increase the amount of primary data. The obtained estimates of ice parameters are consistent with the results of independent observations carried out during the experiment, as well as with the estimates of other authors obtained for ice characteristics in the region of the experiment.
