| Research Abstract |
(1) Generalization and application of the method to analyze satellite remote sensing image data for highly contaminated coastal zone :
For adapting to the situation in Asian coastal environments, in which natural and environmental conditions may differ from those in Japan, it has been attempted to generalize the method developed by Miyazaki and Nadaoka to analyze satellite remote sensing image data for monitoring coastal environments. This method is based on an optical theory and a nonlinear optimization technique. Comparison with the sea-truth data obtained both in Tokyo Bay and Jiaozhou Bay in Tsingtao has shown the fundamental validity and high performance of the present method. Further discussion has been also made for the applicability of the method to highly polluted coastal area in the Philippines such as Manila Bay.
(2) Satellite remote sensing of coral reefs and integration with associated monitoring techniques :
For environmental monitoring of coral reefs, the existence of which

characterizes Asian coastal areas, field measurements in Okinawa islands have been made with associated satellite remote sensing analyses. Besides, a water temperature monitoring network with small memory-type thermometers was deployed along Okinawa islands. A similar attempt to deploy a number of thermometers has been made also in the Philippines in collaboration with a group at the Marine Science Institute of the University of the Philippines. The analyses of the satellite remote sensing data and the thermometer data have been successfully utilized for the investigation of coral bleaching, which occurred worldwide including Okinawa islands and the Philippines in 1998.
(3) An attempt to establish an international joint study project on coral reef - mangrove ecosystem :
Through the present study, an attempt has been made to establish an international joint study project, in which the research groups of the above mentioned MSI/UP, James Cook university and Queensland university, etc. will join, for developing more integrated monitoring systems on coral - mangrove ecosystem.
