    Abstract: 本計畫全程預計以四年時間(97至100年),分區蒐集台灣東北部外海、沖繩海槽南段及琉球弧溝系統之現存海洋地球物理及地質資料及相關文獻。所蒐集的資料及文獻將以表格及圖形方式展示並建檔。經過地物與地質資料的綜合解釋後,最後整合各項資料,於各年度繪製各分區之海洋地質圖及相關圖表。研究結果建立台灣東北海域海洋地物與地質資料庫,分析相關資訊,以完整掌握東北海域海洋地質條件實況,評估海域斷層之特性及其對台灣東北部可能之影響並可作為地調所未來從事海洋地質圖幅繪製時,於資料不足處,測勘與收集地物與地質資料之參考依據。本計畫執行第一年(97年9月16日至12月31日)後,已建立全程計畫研究區域之地物與地質資料目錄及其他相關圖表。另外也針對淡水海域,彙整各項資料後,編輯各項海洋地質圖資。於第二年(98年度)收集棉花嶼及北棉花峽谷海域的各項地物與地質資料,綜合解釋後,繪製各樣海洋地質圖資。另外,亦建立更早期的地物資料(如由九連號所施測的3.5千赫回聲剖面及淺層反射震測剖面)之目錄及資料蒐集。今年(99年度)預期收集宜蘭外海的各項地物與地質資料並分析地調所前期計畫於本年度區域內所採集之海洋沉積物岩心。經綜合分析後,繪製各式相關之主題地質圖資,並建議未來此區海洋地質圖測繪時應補充之調查區域及調查資料。 This project aims to collect and analyze the existing marine geophysical and geological data off the coast of northern Taiwan in the year of 2008 to 2011. The published literature concerning the study area will also be reviewed and synthesized in this project to gain a better understanding of the geological framework and potential geological hazards off northern Taiwan. The collected data will be archived as tables or maps in a database for latter access. In each year, the geological structures and other sedimentary or geophysical features will be mapped out in forms similar to the 1 to 100 thousands-scale marine geological maps. After reviewing and archiving all the existing geophysical and geological data, we hope to provide a reference frame for future data collection for full-scale marine geological mapping projects and to provide a synthesis for potential geological hazards off the coast of northern and northeastern Taiwan. In the first project year (16 September to 31 December 2008), we completed a few catalogues for geological and geophysical data collected offshore northern Taiwan. We also synthesized all the available data offshore Danshui River and prepared maps showing seafloor-sediment distribution and geological structures for the top of the Nanchuang Formation. In the project year of 2009 we synthesized all the existing geological and geophysical data in the areas of the Mienhuayu and the North Mienhua Canyon and prepare relevant geological maps. Additionally, we also archived seismic data collected by sparker system and using R/V Chiulien before 1980s. In project year 2010 we will collect and analyze existing geophysical and geological data offshore Ilan Plain. In addition, sediment cores collected offshore Ilan by previous project funded by Central Geological Survey will be analyzed. Various geological maps will be synthesized from analyzing the newly collected data and existing data. 研究期間:9901 ~ 9912
