| The annual cycle of temperature and
mass balance at Baltimore, 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
red/white boundary is the ice/air interface.
Ice thickness at Baltimore increased from 0.4 m in October 1997 to 1.4 m in June 1998. During summer, the thermistor site became a small pond and melted through to the ocean. However, not all of Baltimore melted. By freezeup, the general Baltimore area was was a mixture of ice about 80 cm thick with many portions that had melted through. |
