Abstract:

Current emphasis upon the high resolution profiles established from ice cores has drawn attention to electrical conductivity measurement(ECM) in ice core studies.In this paper,we describle the technological methods of ECM system and analyse the advantages of ECM on rapid measurement,high spatial resolution and little wreckage.And the applications and progresses of ECM data in ice cores are classified.In addition,particular effort has been made in clarification of the environmental record significance of ECM data to improve a better undersanding of ECM data in ice core studies.
