Temperature: The Ridge

 

The annual cycle of temperature and mass balance at the Ridge, October 1997 to October 1998. The internal ice temperature is displayed using color contours, with blue being cold (-20oC) and red warm (0oC). The gray shaded area represents snow depth, which reached a maximum of about 50 cm. Because of its thickness, we could not determine the position of the ice bottom from the thermistor string. It took the entire growth season for the winter cold pulse to approach the bottom of the ice. In the summer, the ridge ice never became isothermal, with ice in the middle staying a bit cooler (-2 to -4oC).
