Аннотация

Understanding the trend and main causes of the formation and distribution of Blue ice areas (BIAs) in Antarctica may help the search for areas (BIAs) suitable for ice runways for heavy aircraft. Two districts were explored on the glacier within a 50 km radius around the Larsemann Hills. They were isolated as blue ice areas based on the analysis of satellite images. According to the results of surface studies, one of the areas (about 500x5,000 m in size), though initially identified as a BIA based on the analysis of satellite images, has a high density firn covered with sun crust. The second area is indeed a blue ice area of significant size (about 5,000x5,000 m). Similarities and differences have been determined in the formation conditions of the glacier surface in the two areas of assumed BIAs, and an analysis was carried out to identify dominant, necessary and “sufficient” reasons for the sustained existence of BIAs. An obvious link has been found between the distribution of BIAs and the morphology of the subglacial mountain relief and the ice dynamics.
