Abstract

In March 2021, a ground-penetrating radar survey was conducted of the only official ice crossing over the Selenga River in the Mostovaya microdistrict of the Zheleznodorozhny district of Ulan-Ude city. GPR "Oko-2" with antenna blocks AB-1700 (center frequency 1700 MHz) and AB-400 (center frequency 400 MHz) was used for sounding. The thickness of the ice on the ice crossing is 0.5-1.2 m and exceeds the thickness of the ice outside the crossing by 0.1 – 0.2 m. The presence of snow cover outside the crossing limits the freezing of the ice layer. Calibration sounding of the ice with drilling of the well gave the ice permittivity ε = 3.17. The electrical resistivity of the water from the well is 74 Ohm·m at the temperature of 1°C.
