An automatic weather station has been established near the 2004/2005 ice coring site that will record several parameters to help characterise the snow accumulation regime of the local glacier area (Fig.8B).

Parameters measured as of 15 November 2004 are:
  • Air Temperature at 2.5 height
  • Snow accumulation, and air temperature at 1.5 m height
  • Dew point temperature at 2.5 m height
  • Solar radiation (incoming) at 2.5 m height
  • Snow temperatures (thermistor resistance) from 0.5 to 2.5 m depth in at 12 cm intervals

Barometric pressure and wind speed/direction (ultrasonic) sensors are installed but were inoperative when the party left on 16 November.

The installation is expected to operate throughout the upcoming winter. The data will be downloaded from the site in 2005/06 and the installation maintained and the non operational sensors incorporated into the recording program.
