[ACC26-06] Estimation of snow surface patterns from the coast to the inland, Dome-Fuji Station, of Antarctica, using camera images
Keywords:snow dune, snow barchan, sastrugi, glazed surface, snow ripple
The result of our analysis shows that the frequency of the deposition pattern decreases as latitude rises to 73 degrees south (Katabatic wind region) and then it increases slightly. In contrast, the frequency of the erosion pattern increases as latitude rises to 73 degrees south above which it decreases slightly. On the other hand, there have been no outstanding changes in the equilibrium pattern. The analyzed results of latitude dependence agree with the previous research qualitatively. However, the dominant surface pattern in the inland plateau region was still the erosion pattern. Since we analyzed the data of the outward trip, it is necessary to analyze the data of the return trip from the inland to the coast and to investigate a time scale of the surface pattern changes.
