The tensile strength of first-year sea ice
WebMulti-year ice tends to be thicker than new first year ice and, owing to brine rejection, has a higher mechanical strength. As sea ice is more reflective than the surrounding ocean, the … WebAbstract We present the results of tests done to determine the tensile behavior of first-year columnar sea ice over a range of temperatures from −20° to −3°C and strain rates of 10−5 …
