项目摘要
Silver99-09859 Recommended Project is for a multichannel seismic (MCS) survey of the subducting ocean crust off the coasts of Nicaragua and Costa Rica in support of both SEIZE and Subduction Factory objectives in this Margins program study area. The primary objective is to characterize the changing structural nature of the subducting Cocos plate, and to try to relate these changes to known chemical segmentation of the volcanic arc, best shown by ratios such as Ba/La that reflect relative changes in material input into the subduction zone. The MCS survey will be supplemented by three wide-angle, ocean bottom hydrophone (OBH) refraction lines, two perpendicular and one parallel to the trench, as well as by Hydrosweep swath bathymmetry, gravity, and magnetics data. This proposed study is part of a larger, international effort, using the German research vessel R/V Sonne. The MCS and Hydrosweep surveys would be conducted aboard the R/V Maurice Ewing, using its 6 km-long streamer. The R/V Sonne will be used to supply, deploy and recover the OBH's, which will themselves be supplied by GEOMAR.******
Silver99-09859推荐项目是对尼加拉瓜和哥斯达黎加海岸外的俯冲洋壳进行多通道地震勘探,以支持该边缘计划研究区域的捕获和俯冲工厂目标。主要目标是描述俯冲科科斯板块不断变化的结构性质,并试图将这些变化与已知的火山弧化学分段联系起来,最好的体现是反映俯冲带物质输入的相对变化的比值,如BA/La。MCS调查将补充三条广角海底水听器(OBH)折射线,两条垂直于海沟,一条平行于海沟,以及水波扫描带状水浴对称、重力和磁学数据。这项拟议的研究是一个更大的国际努力的一部分,使用的是德国研究船R/V Sonne。MCS和水文扫描调查将在R/V莫里斯·尤因号上进行,使用其6公里长的拖缆。R/V SONNE将用于供应、部署和回收OBH,其本身将由GEOMAR提供。*
