Australia 2016 - AAT Ice Flowers




COUNTRY: AUSTRALIA
ISSUE DATE: 20 September 2016
STAMP SIZE:35 x 35 mm
STAMP DESIGN: Sharon Rodziewicz




At nearly six million square kilometres, the Australian Antarctic Territory (AAT) is the largest part of the continent of Antarctic claimed by any nation. The region was placed under the authority of the Commonwealth of Australia in 1933 and its three year-round stations, Mawson, Davis and Casey, are administered by the Hobart-based Australian Antarctic Division.

The ice flowers or ice ferns represented on these stamps are the names given to the intricate ice patterns that form on glass at AAT stations throughout the winter months. These icy wonders are created when humid air meets a sub-zero glass pane or window. As winter temperatures frequently fall below -40 ° C, they are a common occurrence in Australia’s stations. The icy patterns seem to grow like plants and resemble ferns or flowers, hence their name. Dust and other matter present on the glass can change the way these formations occur. For instance, droplets of water melted by the sun on the inside of a double-glazed window can be transformed into flowery marvels by ice forming overnight.
