Abstract(in Japanese) (See Japanese page)
Abstract(in English) The sliding measurement for local fractal dimension has been already proposed in the previous paper. Using the method, the characteristics or manners of the fluctuation in a given time series can be investigated by "process unit" in which a short discrete time series is taken from the original observed series for the calculations. In this paper, the local fractal dimension has been used as an index showing the manner of fluctuation in the seawater temperature with altitude structure. The considerations have been done with the secular change of the local fractal dimension, based on the results of continuous observation in the seawater temperature around Izu Peninsula using temperature sensor (data logger). Because of incidental cool summer in 2003, which is the first time in ten years in Japan, several features can be found from the viewpoint of Geo-Informatics.
