Abstract

14th (2004) International Offshore and Polar Engineering Conference. 23-28 May 2004. Toulon, France.

Indirect ice and snow thickness measurements were carried out for the winter and spring Antarctic sea ice by using the electromagneticinductive (EMI) device on the East Antarctic pack ice area. 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.
