A thermistor string was installed at the Tundra mass balance site to monitor air, snow, and tundra temperature. The internal tundra temperature is displayed using color contours, with blue being cold (-30 C) and red warm (0 C). The contours show the propagation of the cold front through the ice in fall and winter and how the ice warms and becomes isothermal during melt. The black lines represent snow depth and the position of the surface. Snow depth reached a maximum of about 50 cm. The snow depth was determined from a downward-looking acoustic sensor mounted above the surface and ice thickness was determined from an upward-looking acoustic sensor mounted under the ice.
