A thermistor string was installed at the Beaufort mass balance site to monitor air, ice, and ocean temperature. The internal ice temperature is displayed using color contours, with blue being cold (-20 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 gray shaded area represents snow depth, which reached a maximum of about 30 cm. The boundary between red and navy blue denotes the ice-ocean interface and red-white boundary is the ice-air interface. 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.
