ASTER is characteristic of high spatial resolution. Using the ASTER data, we expect that the studies of oceanography, limnology, lake and sea ice will be possible in detail. Then, we study to develop algorithms about turbidity, aquatic plant, water surface temperature and sea ice. These terms are offered useful informations for the environment science. We wish to report the present status of the studies of application of ASTER data to oceanography, limnology, lake and sea ice.
