Thermal Expansion Measurements in Fresh and Saline Ice Using Fiber Optic Strain Gauges and Multipoint Temperature Sensors Based on Bragg Gratings

Figure 12

Polynomial approximations of the strain-temperature dependencies of ice samples (a) and ECTE versus the temperature calculated for the same samples (b). The curves are constructed with initial ice salinities 9.4 ppt and 2.3 ppt. Long-term tests.
