| 内容記述 | It is well known that red tides cause serious damage to the fishing industry, especially to culture businesses in Japan. If the appearance of the red tide can be predicted, there may be possible action to reduce fishery damage. In this paper, MODIS(Moderate Resolution Imaging Spectroradiometer) data were used to investigate the conditions under which red tides occur in Wakasa Bay. Results of the data analyses for the period from July, 2001 to December, 2019 indicate conditions, for the appearance of the red tide bloom in Wakasa bay as follows : (1) the threshold amount of chlorophyll-a is close to 3mg/m³, (2) the range of SST (Sea Surface Temperature) is limited in a range from 12 to 20℃. We also propose here to utilize MODIS band1 images corresponding to a red band with spatial resolution of 250m together with NDVI (Normalized Difference Vegetation Index) images which has also spatial resolution of 250m, for the confirmation of the red tide. In recent years, the occurrence of red tides in Wakasa Bay has been decreasing, which may be attributed to the improved water quality in the water surrounding Fukui Prefecture. | |||||||
