Abstract: Using ADEOS/AVNIR images in the 1997 winter, the size distribution of sea ice floes in the southern Sea of Okhotsk is analyzed. These images have the high horizontal resolution of 16 m and enable us to recognize ice floes of the diameter from tens of meters to several kilometers. The area and perimeter of each floe are measured by means of image processing, and their statistical features are examined for four ice areas, including the interior ice pack regions, the marginal ice region, and the coastal region. As a result, it is shown that the floe size distribution has self-similarity characteristics within the range of 100 m to 1 km in individual areas and the fractal dimension is estimated to be 2.1 to 2.5, and that the perimeter is highly correlated with the diameter. These results may suggest the ice floe formation process in this size range.
