Remote-Sensing Analyses of Asian Coastal Environments

(1)高污染海岸带卫星遥感图像数据分析方法的推广和应用：为适应亚洲沿海地区自然和环境条件可能与日本不同的情况，尝试推广宫崎骏和Nadaoka等人提出的卫星遥感图像数据分析方法用于海岸环境监测。该方法基于光学理论和非线性优化技术。通过与东京湾和青岛胶州湾海况资料的对比，证明了该方法的基本有效性和高效性。还进一步讨论了该方法在菲律宾高污染沿海地区如马尼拉湾的适用性。(2)珊瑚礁的卫星遥感及其与相关监测技术的结合：用于珊瑚礁的环境监测，其中…为了更好地反映亚洲沿海地区的特点，在冲绳群岛进行了实地测量，并进行了相关的卫星遥感分析。此外，冲绳岛沿线还部署了带有小型记忆式温度计的水温监测网络。与菲律宾大学海洋科学研究所的一个小组合作，菲律宾也进行了部署若干温度计的类似尝试。卫星遥感数据和温度计数据的分析已成功地用于调查1998年包括冲绳群岛和菲律宾在内的世界各地发生的珊瑚白化现象。(3)尝试建立珊瑚礁-红树林生态系统的国际联合研究项目：通过本研究，试图建立一个由上述MSI/UP、詹姆斯·库克大学和昆士兰大学等研究小组共同参与的国际联合研究项目，以开发更多的珊瑚-红树林生态系统综合监测系统。较少

(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 … More 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.
