| Research Abstract |
To develop an algorism for estimating the ice thickness distribution in the seasonal sea ice zone from satellite, the validation measurement was conducted in the southern Sea of Okhotsk and the Lincoln Sea. It is shown that PALSAR (L-band SAR) is useful for this purpose. Based on the PALSAR-derived ice thickness distribution along with the AMSR-derived ice drift pattern and concentration, the ice rheology by Hibler which has long been used in the numerical sea ice model was also validated.
