MCGI W E NDR A FRONT COVER: ROBYN MUNDY Male emperor penguins at Taylor Rookery, 100 km west of Mawson, were photographed incubating their eggs in an ‘emperor huddle’ in June this year. The huddle is a remarkable system of maintaining body warmth in extreme conditions and offers a fantastic sight, particularly when viewed from above. AUSTRALIAN ANTARCTIC MAGAZINE ISSUE 15: 2008 50 YEARS of coopERatioN The United States Antarctic Program’s LC-130 Hercules was a welcome sight on the Davis sea ice runway in October. The runway was specially constructed in a week by Davis station personnel so that an injured expeditioner could be evacuated.
