项目摘要

The result of this study is as follows.1)Extension of oil spill simulation systemTo reduce uncertainties in 2-dimensional sea current information, the assimilation of observation information is realized as part of the system for oil spills analysis and prediction. Satellite data, such as RADAESAT, can extract the sea current information, but considering the physical phenomena in the oil spill accident the time frequency is low. We have used the oil slick by using RADARSAT data as the assimilation data in oil drift model. However, when applying for extracting the sea surface current, because of the low time frequency of RADARSAT, the simulation is inapplicable.In this study, the land base nautical radar is used to extract the sea current as the assimilation data of oil spill simulation system. The result is calibrated by using in sitsu data in Sea of Okhotsuku. This system will be extended for the oil spill simulation from Sakalin. As a result of the comparison between radar data and observation data, there was no verification at the sufficient accuracy.2)Application of the ESI map as a tool which adjusts the conflict between stakeholders in oil-spillBy adding social information such as the fishery information etc. to the ESI map mainly on natural information such as the beach structure etc., the tool which could adjust the interest between stakeholders in the oil accident was made experimentally.3)Discuss on the regional contingency plan for oil-spill accidentUsing the output from 2s result, the regional contingency plan for oil-spill accident the was discussed for arrangement of the present condition of the conflict among the stakeholders from lessons of Anthodia oil spill's incident. This study proposed using an ESI map as a solution, and verified the ESI map positively in the coast of Abashiri, Hokkaido pref..

1）溢油模拟系统的扩展为了减少二维海流信息的不确定性，将观测信息同化作为溢油分析和预报系统的一部分。RADAESAT等卫星数据可以提取海流信息，但考虑到溢油事故中的物理现象，时间频率较低。本文将雷达卫星资料中的浮油作为同化资料应用于油流模式中。但在应用于海面流的提取时，由于RADARSAT的时频较低，无法适用于模拟，本研究利用陆基航海雷达提取海面流作为溢油模拟系统的同化数据。利用鄂霍津海的实测资料对结果进行了标定。该系统将扩展用于Sakalin的溢油模拟。由于雷达数据和观测数据之间的比较，没有验证足够的精度。2）ESI地图作为调整溢油利益相关者之间冲突的工具的应用通过将渔业信息等社会信息添加到ESI地图中，主要是海滩结构等自然信息，3）区域性溢油事故应急预案的探讨利用2S分析结果的输出，结合红藻溢油事故的教训，对区域性溢油事故应急预案的制定进行了探讨，以解决利益相关者之间的冲突现状。本研究提出了使用ESI地图作为解决方案，并在北海道县网走海岸验证了ESI地图。
