On the basis of stratigraphic and physical characters Antarctica ice core study revealed two cate gones (i) ice or depth hoar which shows compaction larger crystal grains greater hardness and dull grey to green colour and (ii) firn which is less compact with smaller grain size and white to off white colour In addition to these major stratigraphic layers 1.5 cm thic sandy layer about 36 cm below the ice surface was also accorded in one bore hole. I our methods were applied to calculate the rate of accumulation and age of the ice in various sector of Antarctica (i) direct measurement through a network of stakes (ii) differentiation of accumulated layers through difference in stratigraphic character, (iii) establishment of a reference horizon through radioactive fallout (artificial activity measurement) (In case of Antarctica 1954 orearly 1955) and (iv). The O 8/O ratio of the deposited snow, giving the temperature at which snow has formed and thus delineating summer and winter layers.It was possible to probe only a few meters of the surface of this ice cover.
