Comparison of sea-ice thickness measurements under summer and winter conditions in the arctic using a small electromagnetic induction device

摘要

Drillhole-determined sea-ice thickness was compared with values derived remotely using a portable small- offset loop-loop steady state electromagnetic (EM) in- duction device during expeditions to Fram Strait and the Siberian Arctic, under typical winter and summer con- Ditions. Simple empirical transformation equations are Derived to convert measured apparent conductivity into Ice thickness.
