| Summary: | Glaciological work was done on the Brunt Ice Shelf near Halley Base in January 1982 by the author who participated in the British Antarctic Survey as an exchanging scientist. Preliminary results of 1.75m pit work and the analysis of a 22m long core obtained with a microdrill system indicate (1) the seasonal variation in acidity of snow, (2) the average annual balance of 41.6g・cm^<-2>・a^<-1> and (3) the depth hoar development in autumn. Further analysis of samples, such as microparticle concentration, gross β activity, δ^<18>O and chemical component, and the climatological interpretation will clarify the process of atmospheric transportation of materials to the Brunt Ice Shelf, the Antarctic coast in the Atlantic sector. |
