The microclimate of Mawson's Hut based on snow and ice core analysis
We report the oxygen isotope ratio (18O) and structural analysis of four 2m long firn cores collected in 1997 from inside Mawson's Hut (consisting of a Main Hut and a Workshop), Commonwealth Bay, Antarctica, and 25 snow samples collected in 2001 in the vicinity of the huts. Our aim is to examin...
