摘要：

The evaluation of a small electromagnetic induction sounding system for use in airborne measurement of sea-ice thickness is discussed, as are the results from arctic field testing. Also outlined are the system noise and drift problems encountered during arctic field evaluation, problems which adversely affected the quality of the sounding data. The sea-ice sounding results indicate that for ice floes with moderate relief it should be possible to determine thickness to within 5%, but that because of sounding footprint size and current model algorithm constraints, steep-sided pressure ridge keels cannot be well defined. -from Authors
