Abstract: Field results from a man-portable electromagnetic induction sounding instrument, with special plug-in data processing modules for the remote measurement of sea ice thickness, are discussed. The field trials indicate that the instrument was capable of estimating undeformed sea ice thickness, with a snow cover, generally within about 5% of the drill hole measured thicknesses from about 1.25 to 4.5 m. No ice under 1.25 m was sounded in this study. Instrument thickness determinations of multiyear sea ice over about 4.5 m thick showed larger deviation from the drill hole snow and ice thickness measurement. It is proposed that the undulating multiyear sea ice relief is the major cause of the EM deviation.
