| Research Abstract |
Using the snow/firn samples and data obtained by traversing the interior of the Antarctic ice sheet, we studied physical mechanisms of the formation of the strata within snow and firn. Major findings include spatial distribution of the depositional environment in Antarctica, seasonal effects on firn density and spatial distribution of the subglacial environment. In addition, we found that polarization ratio of the microwave emissivity from the ice sheet surface is well correlated to accumulation rate observed by radar sounding.
