| The annual cycle of temperature and
mass balance at Tuk, October 1997 to October 1998. The internal ice temperature
is displayed using color contours, with blue being cold (-20oC) and red warm
(0oC). The contours show the propagation of the cold front through the ice in
fall and winter and how the ice warms and becomes isothermal in the summer. 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 the
red/white boundary is the ice/air interface.
Ice thickness at Tuk increased from 3.1 m in October 1997 to 3.3 m in June 1998. During summer melt, there was 55 cm of surface ablation and 50 cm of bottom ablation. In winter, snow depths were 20-30 cm. This relatively shallow snow combined with the thick ice resulted in cold ice temperatures at Tuk during winter. |
