This study investigated the effect of saline slush snow layer over the sea ice and seawater-filled gap to the snow and sea ice thickness measured by EMI. A result shows underestimations of EMI thickness, which might be caused by high conductive seawater-filled gaps between ice floes, appeared on thicker ice over 3.5 m. This study improved the validity of applying a multi-rafted ice model for these ice conditions.International Society of Offshore and Polar EngineersConference Paperapplication/pdfhttp://hdl.handle.net/2115/38936https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/38936/1/2004-ki-02-1.pdf1098-6189Proceedings of The Fourteenth (2004) International Offshore and Polar Engineering Conference8068122004engpublisher
