要約(英語): The flow of freshwater into the sea, termed as submarine groundwater discharge, is a key factor for understanding the hydrological cycle in both the sea and land regions. The numerous positions from which freshwater gushes out or its quantity impedes the understanding of its properties. In our previous study, we have detected groundwater discharge points arising due to the difference in freshwater and seawater by using the multispectral Landsat ETM+ signals with 30m spatial resolution. The details of seawater surface information regarding the submarine groundwater discharge haven't been obtained yet. Therefore, this paper analyzes features in water properties around the groundwater discharge points by using the ALOS AVNIR-2 outputs, providing 10m spatial resolution. That is, classified maps obtained by the k-means clustering are compared with the measurements in the ground survey, the geologic map, and the estimation map of the relative salinity. Our experimental results obtained by the AVNIR-2 are in considerable agreement with the realities in the study area.
