Summary Oil spills in the ocean often have serious impacts on marine ecosystems and economic activity; however, oil spills can be effectively controlled and cleaned up if their temporal and spatial variations are well known. Due to the large scale detection capability in the space domain, remotely sensed images are often applied to detect the oil spills. Marine X-band radar, which was first used for navigation, is one of the most useful devices to detect the spatio-temporal variations of oil spill. In addition to oil spill detection, accurately forecasting oil spill movement is essential for planning and emergency decision making. The objectives of this project are to develop an oil spill detection technology based on marine X-band radar and to build up an oil spill forecasting system. The study will be performed in three phases. The first phase will propose the prototype of oil spill sensing technology based on the marine X-band radar and develop the numerical model for tracking oil spills. The second phase will test the radar system, ocean modeling and oil spill modeling. The final phase will integrate remote sensed data in the oil spill modeling. The results of this study can be used not only to assist authorities on the maintenance and management of environment safety, but also to improve technology for tracking the oil spills.

The completed work in this year can be divided into three parts: The first part is oil spill monitoring. The image processing based on the algorithm of Cross Teager Kaiser Operator (CTKO) has been discussed and tested using simulated oil spill images. In the second part of the oil spill simulation: the high resolution triangular meshes have been build in Anping Harbor and Taipei Harbor. And then the ocean modeling and oil spill modeling have been build up and test. The qualitative analysis and quantitative analysis show that the simulation results are reasonable, especially tide current direction. It's worth noting that the resolution of partial tides as boundary condition has impact to tide current simulation. For the third part of this project, this study decoded and analyzed the data observed from WERA high frequency radar system, so as to obtain the sea surface velocity information.
