Methodological Basis of Estimating the Mean Thickness of the Consolidated Layer of Ice Ridges and Stamukhas from the Disrtibution of Solid Phase Volumetric Content in Sea Ice

The penetration rate record during electrical and hot water thermal drilling of ice ridges and stamukhas allows obtaining the information about their internal structure. The penetration rate is inversely proportional to the volumetric content of ice solid phase. The dependence of inverse rate versus depth is, in fact, the distribution of solid phase volumetric content versus depth. By averaging these distributions for all boreholes, it is possible to obtain the average distribution of the volumetric content of the solid phase versus depth for the area investigated. The paper describes the method which allows estimating the mean thickness of the consolidated layer of ice ridges and stamukhas by this distribution. The condition of validity of this estimation is given. The examples of application of such method are presented. The difference between the consolidated layer mean thickness determined by this method and thickness determined by the location of hard ice, soft ice and void zones is less than 5 %.
