Research on sea ice physical characteristics is the principal means to understand the sea ice formation process.By the 19th Chinese Antarctic Research Expedition,the 1-D thermodynamic sea ice model based on freezing degree day was used to estimate the landfast sea ice development in Nella Fjord.Comparing the modeled ice thickness with the measured ice thickness,in relation to atmospheric condition as well as visual observations of ice condition,it is found that multiyear ice has developed in Nella Fjord.The structure,salinity and stable oxygen isotopic properties of the samples collected on the landfast sea ice were also used to study the features of ice textural and salinity profiles,the contribution of snow-ice to total sea ice thickness,the percentage of superimposed ice,and the fraction of snow in the snow-ice layers and in the total sea ice thickness in Nella Fjord.The structure analysis of the sea ice cores reveals that there are a general structure of horizontal c-axis in columnar ice,a granular surface layer and a columnar basal layer with a "buried" granular ice layer between two columnar ice layers.Both the salinity profiles and δ18O profiles show the multiyear ice developing in Nella Fjord.The textural and isotopic properties of sea ice indicate that the thermodynamic mechanisms are responsible for the development of the landfast ice in Nella Fjord.The results are well agreement with the visual observations of sea ice conditions between Jan 2000 to Feb 2003.No ridging and rafting can be seen.The ratio of the superimposed ice to the total ice thickness is 5 01 % on the average.Using different isotopic criteria to distinguish snow-ice layers,the ratio of snow-ice layers to the total ice thickness is estimated from 16 4 to 37 9% on average in the study region.The ratio of snow in the granular ice layers to the total sea ice thickness(by mass)is estimated from 0 8% to 23 5%.
