Preliminary Results and Review of Sea Ice Elasticity and Related Studies
There are many methods of determining elasticity that can be used on ice. These can be divided into laboratory and field studies, and further divided into static and dynamic determinations. Two valuable in-place field methods are deflection and seismic. Preliminary results from a mass of data indicate that the elasticity of sea ice is less than fresh ice and varies over at least an order of magnitude. Results obtained from the seismic method are generally at least an order of magnitude greater than small sample static values. Preliminary analysis indicates that elasticity can be related to a parameter which includes temperature, liquid-and air-content.
