AbstractUnder-ice sonar profiles and surface laser profiles of the Arctic pack ice have been analyzed using power-spectrum techniques to extract significant spectral peaks corresponding to spatial periodicies in the ice. The analysis suggests that, for a section of ice sampled by two intersecting under-ice profiles, the ridges are not randomly oriented. Moreover, the lineation or directionality of the ridges may be approximately determined from the two intersecting profiles. Also the spectra from surface profiles of multi-year ice and from surface profiles of first-year ice are of a much different nature, thus suggesting a technique for determining ice types from laser profiles.
