Young's Modulus for Sea Ice

A study is made of the dependence of Young's modulus for small samples of sea ice on their brine content. Young's modulus is determined from the velocity of ultrasonic waves through the samples and the brine content from their salinity and temperature. It is found that, over a range of brine content of about 0.01 to 0.1 as a fraction of the total volume, Young's modulus decreases linearly with increasing brine content. Its value is 10.0 × 1010 dyne cm−2 when the brine content is 0 and 6.5 × 1010 dyne cm−2 for a brine content of 0.1.
