Glaciological Studies in the Vicinity of Syowa Station, Lützow-Holm Bay, East Antarctica
There is a marked ablation zone some 15 km wide along the periphery of the Soya Coast, Lützow-Holm Bay, and here the firn limit has a maximum height of about 600 m. A controlled analysis of the snow-firn stratigraphy on the marginal slope of the ice sheet at 700 m elevation was carried out on Nov. 3...

There is a marked ablation zone some 15 km wide along the periphery of the Soya Coast, Lützow-Holm Bay, and here the firn limit has a maximum height of about 600 m.

The mean annual net accumulation for the period 1956-1965 was calculated as 7.1 ± 2.2 g/㎠.
